Education Excellence: Strategies for Quality Improvement (2026)

Education Quality Improvement: A Comprehensive Guide to Evidence-Based Strategies

Education quality directly impacts student success, workforce readiness, and economic growth. Whether you’re a parent evaluating schools, an educator seeking professional development, or an administrator planning institutional improvements, understanding proven quality improvement strategies is essential. This comprehensive guide covers the most effective, research-backed approaches to elevating education standards across K-12 and higher education settings.

The Foundation: Understanding Education Quality Improvement

Education quality improvement encompasses systematic changes designed to enhance student learning outcomes, teacher effectiveness, and institutional performance. Quality improvement isn’t a single initiative but rather a collection of interconnected strategies that address the multiple factors affecting student success. Research from the National Assessment of Educational Progress (NAEP) and international studies like the Program for International Student Assessment (PISA) consistently show that the highest-performing education systems combine several key elements: well-trained teachers, manageable class sizes, adequate resources, and student-centered instruction.

The goal of quality improvement is not merely to raise test scores, though improved achievement is often a positive outcome. Rather, comprehensive quality improvement focuses on developing critical thinking skills, fostering student engagement, promoting equity, and preparing learners for college, careers, and civic participation. This requires a holistic approach that addresses structural factors like funding and class size alongside pedagogical improvements in how teachers teach and students learn.

Effective quality improvement efforts typically follow a cycle of assessment, planning, implementation, and evaluation. Schools and districts identify current performance levels through standardized assessments, classroom observations, and student surveys. They then develop targeted improvement plans, implement changes with sufficient time and support, and continuously monitor progress through multiple measures of success. This data-driven, continuous improvement mindset distinguishes effective quality initiatives from one-time programs that lack sustainability.

Teacher Development: The Highest-Leverage Strategy

Teacher quality is the single most influential school-based factor on student achievement. Research consistently demonstrates that students taught by highly effective teachers gain significantly more academically than peers taught by less effective teachers, with effects that accumulate over years. Investing in teacher professional development and creating systems that support continuous improvement directly translate to improved student outcomes.

Comprehensive Professional Development Programs

Effective professional development goes far beyond one-day workshops. The highest-impact professional development is ongoing, job-embedded, and focused on actual instructional practices. Research-backed professional development models include peer observation and coaching, collaborative lesson planning, and study groups focused on specific instructional strategies. Schools like those in the Uncommon Schools network and organizations like Learning Forward have documented significant achievement gains through sustained professional development focused on concrete teaching practices.

Professional development should directly address teachers’ daily classroom challenges. For example, if student engagement data shows that class discussions are superficial, professional development might focus on questioning techniques, wait time, and discussion facilitation. When professional development is connected to school improvement goals and classroom practice, teacher implementation rates increase dramatically, typically from 10 percent to 80 percent or higher.

Leading school districts allocate between 3 and 5 percent of their budgets to professional development and create dedicated time for learning activities. This might include early dismissal days, professional learning communities that meet weekly, or dedicated planning periods where teachers collaborate on lesson design and analyze student work together. The cost of quality professional development typically ranges from 1,500 to 5,000 dollars per teacher annually, but research shows strong return on investment through improved student achievement.

Teacher Certification and Credentialing Standards

Clear, rigorous standards for teacher certification help ensure that all educators have mastered content knowledge and pedagogical skills. States and countries with stronger teacher certification requirements, like those requiring passes on comprehensive content and pedagogy exams, consistently show higher student achievement. The United States varies significantly in teacher certification requirements across states, with some states requiring masters degrees in education and others requiring only bachelor’s degrees.

Beyond initial certification, ongoing professional standards keep teachers accountable and motivated for continuous improvement. The National Board for Professional Teaching Standards (NBPTS) offers voluntary advanced certification for experienced teachers who demonstrate excellence. Teachers who obtain NBPTS certification show measurable gains in student achievement, particularly in high-poverty schools. The certification process involves developing a comprehensive portfolio, taking rigorous exams, and participating in peer review, costing approximately 2,500 dollars but often resulting in salary supplements.

Compensation and Retention

Competitive compensation is essential for attracting and retaining talented teachers, yet teacher salaries remain below those of other professions requiring similar education levels. The average teacher salary in the United States is approximately 67,000 dollars annually, while comparable professionals in other fields earn 80,000 to 100,000 dollars. This salary gap contributes to ongoing teacher shortages, particularly in high-need subjects like mathematics, science, special education, and English language learning.

Schools addressing this challenge through differentiated compensation models, such as performance pay, subject matter bonuses, and location-based incentives, see improved recruitment and retention. However, research on performance pay is mixed; it works best when teachers trust the evaluation system, when bonuses are meaningful (at least 5 to 10 percent of base salary), and when the focus is on growth and improvement rather than punishment. The Teaching and Learning International Survey found that job security, professional respect, and autonomy matter as much as salary in teacher retention decisions.

Personalized and Differentiated Learning Approaches

One-size-fits-all instruction cannot meet the diverse needs of today’s classrooms. Personalized learning, differentiated instruction, and student-centered approaches recognize that learners have different backgrounds, abilities, interests, and learning preferences. Research on these approaches consistently shows improved engagement, motivation, and academic achievement, particularly for struggling students and those from underrepresented groups.

Personalized Learning Systems and Adaptive Technologies

Personalized learning tailors the educational experience to individual student needs, preferences, and pace. This might involve student choice in topics or formats, flexible pacing based on mastery rather than time, or adaptive software that adjusts difficulty based on performance. Adaptive learning platforms like ALEKS, DreamBox, and IXL use algorithms to identify knowledge gaps and recommend appropriate practice problems or lessons.

Research from the RAND Corporation found that adaptive learning can produce achievement gains equivalent to 0.2 to 0.4 standard deviations, particularly when combined with teacher support and guidance. However, technology alone is not sufficient; teachers must use student progress data to inform instruction and provide targeted support. Costs for adaptive learning platforms typically range from 15 to 50 dollars per student annually, making them relatively affordable at scale.

Successful personalized learning implementations combine technology with strong teaching. Teachers use progress data from adaptive systems to identify students needing intervention, form flexible small groups for focused instruction, and provide real-time feedback. Schools like Summit Learning Program and High Tech High have demonstrated that personalized learning, when implemented well, produces high achievement with strong graduation rates and college readiness metrics.

Differentiated Instruction Strategies

Differentiated instruction involves modifying content, process, or products based on student readiness, interest, or learning profile. Rather than expecting all students to learn the same content in the same way at the same pace, teachers provide multiple pathways to learning. Practical differentiation strategies include learning stations, flexible grouping, tiered assignments, and choice boards.

Learning stations allow students to rotate through different activities targeting the same learning objective at varying difficulty levels. A math teacher might have a station where advanced students explore algebraic functions, another where proficient students practice multi-step equations, and a third where students building foundational skills work with equations and variables through manipulatives. All stations address the same standard but meet students where they are.

Flexible grouping ensures that students aren’t permanently assigned to high or low groups, which can limit expectations and reinforce achievement gaps. Teachers reassess regularly and regroup based on current needs. A student might be in an advanced group for reading comprehension but a developing group for reading fluency. Research shows flexible grouping maintains high expectations for all students while providing targeted support.

Student-Centered and Inquiry-Based Learning

Student-centered instruction places learners at the heart of the educational process, emphasizing active engagement, choice, and responsibility for learning. Rather than passively receiving information from teachers, students investigate questions, solve real-world problems, and construct understanding through experience. Inquiry-based learning, project-based learning, and competency-based education are student-centered approaches showing strong research support.

Inquiry-based learning begins with compelling questions or phenomena, requiring students to investigate, hypothesize, experiment, and draw conclusions. For example, rather than simply teaching cell structure, students might investigate how cell size relates to function or design experiments to test how cells respond to osmotic pressure. This approach deepens understanding and builds scientific thinking skills. A meta-analysis in Science Education found that inquiry-based instruction produces achievement gains of 0.4 standard deviations or higher.

Project-based learning engages students in extended investigations addressing real-world challenges. A high school engineering class might design water filtration systems for a community partner, requiring students to apply chemistry, physics, mathematics, and design principles. Project-based learning develops collaboration, communication, and critical thinking while increasing engagement. High Tech High schools using project-based learning exclusively report 90 percent college enrollment rates, well above national averages.

Addressing Class Size and Overcrowding

Class size directly impacts student achievement and teacher effectiveness, yet this important factor receives inconsistent attention in policy discussions. Research consistently documents that smaller classes allow more individualized attention, increase student participation, reduce behavior problems, and improve achievement. However, the effects of class size reduction are not uniform; effects are largest for economically disadvantaged students and vary by grade level, with effects strongest in early grades.

Research on Optimal Class Size

The landmark Tennessee STAR (Student/Teacher Achievement Ratio) experiment in the 1980s randomly assigned students to regular-size classes (around 25 students) and small classes (around 15 students). Results showed achievement gains of 0.15 to 0.20 standard deviations in early grades for small classes, with effects even stronger for disadvantaged students. Follow-up studies found these students had higher high school graduation rates and college attendance. Subsequent research has generally confirmed these findings, with most studies showing effects of 0.05 to 0.30 standard deviations depending on implementation and context.

Optimal class size depends on instructional model. Traditional lecture-based instruction can accommodate larger classes, while project-based learning, lab work, and discussion-based instruction require smaller classes. Elementary teachers with students all day need smaller classes than secondary teachers teaching multiple class periods. Special education and English language learner instruction require smaller classes for effectiveness. Most research suggests benefits from classes below 20 students, with strongest benefits below 15 students.

Strategies for Managing Overcrowding

Many schools face capacity constraints, particularly in rapidly growing areas and under-resourced districts. Several strategies can address overcrowding while maintaining or improving quality. Multi-track year-round schooling adjusts the calendar so different groups of students attend during different blocks, allowing facilities to serve more students. Research on year-round schooling shows neutral to positive effects on achievement, particularly for disadvantaged students, though implementation quality matters substantially.

Boundary adjustments and controlled choice programs redistribute students to balance enrollments and reduce overcrowding in high-demand schools. Some districts use socioeconomic diversity or achievement levels as criteria, ensuring that no school becomes concentrically isolated by poverty or prior achievement. Capacity planning that projects enrollment five to ten years forward and coordinates housing development with school capacity helps prevent acute overcrowding.

When class size reduction isn’t immediately possible, schools can partially offset overcrowding effects by using paraprofessionals to provide targeted small-group instruction, implementing collaborative learning structures that increase peer interaction, and creating flexible seating arrangements. While not equivalent to small classes, these strategies can improve engagement and achievement when implemented consistently. Cost considerations are significant; reducing class size from 30 to 20 students requires approximately 33 percent more teachers and facilities, representing substantial budget impacts.

Strategic Technology Integration in Learning

Technology in education is not an end in itself but rather a tool for supporting effective teaching and learning. The highest-achieving schools and districts use technology strategically to address specific learning challenges, enhance engagement, provide personalized instruction, or increase access. Technology can be transformative when implemented well, but poorly integrated technology wastes resources and may actually detract from learning.

Evidence-Based Technology Implementation

Research on technology effectiveness is nuanced. Technology produces achievement gains when it supports specific instructional purposes, is aligned with curriculum standards, allows interaction and feedback, and is coupled with quality teaching. A meta-analysis of 109 studies found positive effects for technology-supported instruction (0.30 standard deviations), with larger effects for blended learning combining online and in-person instruction. However, technology used primarily as a substitute for traditional lecture shows minimal or negative effects.

Blended learning models combining face-to-face instruction with online components show particular promise. Students engage with content online at their own pace, freeing class time for discussion, project work, and teacher support. This might involve students watching video lessons at home and using class time for problem-solving and collaboration. Research from organizations like the Christensen Institute documents achievement gains and improved engagement in well-designed blended learning implementations.

Technology for formative assessment and data collection enables teachers to monitor understanding in real-time and adjust instruction. Systems like Formative, Google Classroom, and learning management systems provide immediate feedback and help teachers identify struggling students quickly. When teachers use this data to differentiate instruction, achievement gains are significant. However, simply collecting data without responsive instructional changes produces minimal benefits.

Cost-Benefit Analysis and Technology Choices

Technology investments require careful consideration of costs and expected benefits. Device costs have decreased substantially, with Chromebooks and tablets available for 200 to 400 dollars per unit. However, total cost of ownership including software licenses, technical support, professional development, and replacement is significantly higher. Educational software ranges from free open-source options to subscriptions costing 30 to 100 dollars per student annually.

Schools should prioritize technology addressing specific needs identified through data. If data shows that students lack foundational mathematics skills, investment in adaptive mathematics software with teacher training might be appropriate. If students have limited access to science labs, virtual lab simulations may be valuable. However, simply purchasing devices without instructional purpose or professional development typically produces disappointing results. The most effective approach involves teachers and administrators identifying learning challenges, researching evidence-based technology solutions, piloting with quality implementation and teacher support, and scaling with ongoing evaluation.

Creating Effective Learning Environments and Cultures

Physical and cultural learning environments profoundly influence student engagement and achievement. This includes physical facilities, classroom climate, school culture, and student-teacher relationships. Schools creating safe, welcoming, respectful environments where students feel they belong show significantly better outcomes across achievement, attendance, behavior, and college enrollment.

Physical Learning Spaces

Well-designed learning spaces support effective instruction and student well-being. Research on classroom design shows that natural lighting, appropriate temperature control, minimal noise, and clean, well-maintained facilities improve focus and reduce stress. Flexible furniture arrangements supporting collaborative learning, movement, and different instructional configurations are superior to fixed rows of desks. Schools like those in the Vittra network in Sweden and many Montessori schools design spaces allowing students to move between areas supporting different types of learning.

Access to outdoor spaces, physical activity areas, and nature improves mental health, engagement, and achievement. Research on green schools shows that outdoor classroom time, nature-based learning, and access to green spaces reduce anxiety, improve focus, and increase motivation. The biophilic design approach intentionally incorporates natural elements, light, and views into school design.

Libraries and makerspace areas supporting research, creativity, and hands-on learning are increasingly recognized as essential. Schools investing in librarians, expanded library hours, digital resources, and maker equipment report increased research skills, improved reading, and stronger college readiness. Cost considerations include renovation of spaces and equipment purchases ranging from basic makerspaces under 10,000 dollars to comprehensive centers with 3-dimensional printers and other equipment exceeding 50,000 dollars.

Positive School Culture and Student Belonging

School culture the shared values, norms, and beliefs significantly influences achievement and well-being. Schools with strong positive cultures characterized by high expectations, mutual respect, collaboration, and celebration of diverse perspectives show higher achievement, better attendance, less discipline issues, and lower dropout rates. Schools with toxic cultures characterized by fear, disrespect, or low expectations show opposite outcomes regardless of resources.

Student belonging the sense that one is valued, welcomed, and has a place in the school community predicts achievement, engagement, attendance, and mental health. Research by Gregory Walton and Geoffrey Cohen shows that brief interventions affirming belonging, such as having struggling students reflect on their belonging concerns or read about diversity in the student body, produce meaningful achievement gains for disadvantaged students. Whole-school approaches to belonging include inclusive curriculum representation, affinity groups supporting underrepresented students, and relationship-building activities.

Positive behavioral and social-emotional learning systems create behavioral expectations, teach desired behaviors explicitly, and reinforce positive choices. Schools implementing evidence-based systems like Positive Behavioral Interventions and Supports (PBIS) see reductions in discipline referrals, suspensions, and dropouts alongside improved achievement. PBIS implementation requires professional development, data systems for monitoring behavior, and sustained commitment, but research shows strong return on investment through improved attendance and engagement.

Assessment and Data-Driven Improvement

Strategic assessment and thoughtful use of data enable schools to identify needs, monitor progress, and adjust approaches. However, over-reliance on standardized testing, misuse of data for punitive purposes, or assessment without responsive action can be counterproductive. Effective assessment systems balance multiple measures to provide comprehensive understanding of student learning and growth.

Balanced Assessment Systems

Comprehensive assessment includes standardized measures, classroom formative assessment, performance assessments, and student self-assessment. Standardized tests provide comparable data across students and schools but capture only a narrow range of skills and are influenced by socioeconomic factors. Classroom formative assessment through observation, questioning, quizzes, and student work analysis provides real-time information for instructional adjustment. Performance assessments requiring students to apply learning to complex tasks reveal deeper understanding than multiple-choice tests.

Formative assessment integrated into instruction produces stronger achievement gains than summative testing alone. When teachers use frequent low-stakes quizzes, observations, and student work to identify misunderstandings and adjust instruction, achievement improves significantly. Digital formative assessment tools like Formative, Quizizz, and Nearpod provide immediate feedback and allow teachers to identify struggling students quickly. Research by John Hattie identifies formative assessment feedback as having one of the strongest effect sizes on achievement.

Growth measures comparing student progress over time are more equitable than absolute measures, particularly for disadvantaged students or those learning English. Value-added models attempt to measure teacher and school contribution to student growth by accounting for starting points. While imperfect, growth measures can identify schools effectively supporting underrepresented students, not just those starting ahead.

Data Systems and Use

Data systems enabling collection, analysis, and sharing of student information support improvement. Student information systems managing attendance, behavior, grades, and assessment results provide foundation for analysis. Dashboards presenting data visually help teachers and administrators identify trends and patterns. Data warehouses combining multiple data sources support sophisticated analysis of school functioning.

However, data systems are only valuable if staff use data for improvement. Professional development in data literacy, development of collaborative data teams examining results and planning actions, and leadership support for data-informed decision making are essential. When teachers examine data collaboratively to identify student needs, set improvement goals, implement targeted instruction, and monitor progress, achievement gains are significant. When data is collected without analysis or action, it’s a waste of resources.

Funding, Resources, and Equitable Resource Distribution

Adequate and equitable funding is a prerequisite for quality improvement. Vast disparities in school funding across districts and states contribute substantially to achievement gaps. Schools in high-poverty areas typically receive fewer resources than affluent schools, despite students’ greater needs. Addressing this inequity is essential for quality improvement, particularly for underrepresented students.

School Finance and Achievement Relationships

Research consistently shows positive relationships between school funding and achievement. A meta-analysis by C. Kirabo Jackson found that ten percent increases in per-pupil spending from ages 5 to 18 increased earnings and college attendance and reduced poverty rates in adulthood. School finance reforms directing resources to low-income districts show achievement gains, particularly for disadvantaged students. Current per-pupil spending varies widely, from under 8,000 dollars annually in some districts to over 25,000 dollars in wealthy districts, creating vast resource disparities.

Adequate funding enables schools to hire experienced teachers, provide professional development, maintain facilities, purchase materials and technology, and support students. Research on adequacy suggests that per-pupil spending of 15,000 to 18,000 dollars enables schools to implement evidence-based practices at high quality. However, money alone is insufficient without wise allocation and strong implementation.

Within-School Resource Allocation

How schools allocate resources significantly influences outcomes. Schools allocating more to classrooms and less to administration, prioritizing teacher quality and professional development, and directing resources to highest-need students show stronger achievement. However, many schools allocate resources equally across all students despite disparate needs or allocate more to high-performing students through advanced program placement.

Weighted student funding models directing more resources to students with greater needs help address disparities. A student from a low-income family, English language learner, or with disabilities receives higher funding, enabling schools to provide appropriate support. Special education funding, English language learner support, and poverty-targeted allocations help ensure adequate resources for all students. Implementation requires political will to reallocate resources from higher-income schools to lower-income schools.

Outcome-Based Education Framework for Higher Education

Outcome-Based Education (OBE) frameworks increasingly guide higher education quality improvement. Rather than focusing solely on inputs like time spent in class or credit hours, OBE emphasizes demonstrated learning and competency. This shift aligns higher education more closely with workforce needs and accountability expectations.

Learning Outcomes and Competency Definition

Learning outcomes define what students should know and be able to do after completing a program. Well-designed outcomes specify knowledge, skills, and dispositions at appropriate levels of cognition. Bloom’s taxonomy and variations like Fink’s taxonomy help educators write outcomes at appropriate cognitive levels, from basic knowledge to synthesis and evaluation. Examples of learning outcomes include students can analyze complex problems, demonstrate proficiency in disciplinary content, communicate effectively across audiences, and collaborate in diverse teams.

Competency-based approaches define specific competencies and measure attainment rather than seat time. Competency-based programs allow faster progress for students who master material quickly and provide additional support for those needing more time. Accredited competency-based programs, increasingly available from universities like Western Governors University, Southern New Hampshire University, and Brandman University, allow self-paced progression while maintaining quality standards.

Curriculum Design and Assessment Aligned to Outcomes

When outcomes are clear, curriculum design and assessment align naturally. Curriculum mapping documents how courses and assignments develop specific outcomes. Assessment plans identify what evidence demonstrates learning outcomes and at what point students demonstrate competency. Direct assessments of learning like capstone projects, portfolios, and performance assessments show what students can actually do. Indirect measures like surveys and focus groups capture student perception of learning and satisfaction.

Rubrics defining quality levels for outcomes help provide consistent evaluation. An outcome that students will communicate effectively across audiences might be assessed through written papers, presentations, and collaboration rubrics specifying criteria for exceeding expectations, meeting expectations, approaching expectations, and falling below expectations. Clear rubrics help students understand expectations and help faculty provide targeted feedback.

Improvement Strategy	Implementation Cost per Student	Time to Results	Effect Size	Best For
Class Size Reduction	2,000 to 4,000 annually	1 to 2 years	0.15 to 0.30	Early grades, disadvantaged students
Professional Development	1,500 to 5,000 per teacher	6 to 18 months	0.20 to 0.50	All settings, highest return
Adaptive Learning Technology	15 to 50 per student	1 to 2 years	0.20 to 0.40	Mathematics, skills practice
Project-Based Learning Implementation	500 to 2,000 per school	6 to 18 months	0.20 to 0.40	Engagement, deep learning
PBIS Behavioral System	100 to 500 per school	1 to 3 years	0.10 to 0.25	Discipline, attendance, engagement

Equity and Supporting Underrepresented Students

Quality improvement must address persistent achievement gaps between student groups. Underrepresented students including students of color, students from low-income families, students learning English, and students with disabilities consistently show lower achievement, graduation rates, and college enrollment. These gaps are not inevitable but reflect systemic inequities in resources, opportunities, and treatment. Quality improvement addressing equity requires intentional action.

Culturally Sustaining and Responsive Teaching

Culturally responsive teaching acknowledges and builds upon students’ cultural backgrounds, incorporates diverse perspectives and voices into curriculum, and develops critical consciousness. Rather than treating diversity as a problem to overcome, culturally responsive teachers view students’ cultural backgrounds as assets and strengths. Research by Gloria Ladson-Billings shows that culturally responsive teaching produces achievement gains and increased engagement, particularly for students of color.

Culturally sustaining pedagogy, described by Django Paris, goes further by helping students sustain and develop their cultural practices and identities while developing academic competence. This might involve incorporating students’ languages and dialects into instruction, studying authors and historical figures from students’ cultures, and connecting curriculum to issues affecting students’ communities. Schools implementing culturally responsive approaches show particularly strong results for African American and Latino students and students learning English.

Addressing Stereotype Threat and Belonging Uncertainty

Stereotype threat the anxiety that arises when students worry they might confirm negative stereotypes about their group reduces performance and engagement, particularly in domains like mathematics and science where gender and racial stereotypes persist. Brief interventions addressing belonging uncertainty produce meaningful achievement gains, particularly for underrepresented students. These include self-affirmation exercises, belonging affirmation activities where students learn diversity in the student body, or having older students who succeeded share messages of belonging.

School practices reducing stereotype threat include emphasizing that ability is developed through effort rather than fixed, recognizing that belonging concerns are normal, and creating inclusive classroom communities. Research by Geoffrey Cohen shows that simple interventions like social belonging affirmation activities (a few writing exercises reflecting on relationships) produce achievement gains of 0.3 to 0.5 standard deviations for underrepresented students over time.

Advanced Placement and Gifted Program Access

Advanced Placement, honors, and gifted programs provide more rigorous curriculum and advanced opportunities but are often inaccessible to students of color and students from low-income families. Referral bias, overreliance on test scores reflecting test access and preparation, and underestimation of capability contribute to underrepresentation. Schools addressing this through universal screening using multiple measures, removing barriers to entry, and providing bridge support to help underrepresented students succeed in advanced courses see dramatically increased diversity in advanced programs with maintained or improved achievement for all students.

Schools like those in the Acceleration Consortium that provided universal access to algebra in middle school saw dramatic increases in students taking advanced mathematics by high school, particularly for students of color. Achievement remained high, and participation gaps narrowed. Providing advanced opportunities combined with support helps develop talent among all students.

Implementation and Sustainability of Quality Improvements

Evidence-based strategies only improve outcomes if implemented with fidelity and sustained over time. Many schools adopt promising practices but abandon them before achieving significant results or implement them superficially without quality. Understanding implementation science and change management increases the likelihood of successful, sustained improvement.

Change Management and Implementation Planning

Monitoring Implementation and Outcomes

Schools should measure both implementation quality (Are we
