How to Fund Evidence-Based Professional Development for Teachers

Federal and state funding models increasingly require districts to prove that professional development spending is evidence-based. For district leaders wondering how coaching programs fit into these requirements, the short answer: coaching that meets any of ESSA’s four evidence tiers qualifies. The key is understanding those tiers, documenting your program’s alignment, and making the case to your state or grant funder.

The FY2027 federal budget proposal would consolidate 17 education programs into a single block grant called the Make Education Great Again (MEGA) program, with specific mandates for evidence-based literacy and mathematics instruction. Whether or not MEGA passes as written, the language will heavily influence how states plan their spending. This guide walks through what “evidence-based” means under ESSA, how coaching aligns to MEGA’s proposed funding pathways (including the specific literacy and math mandates), and how to stretch professional development dollars when budgets tighten.

What Does “Evidence-Based” Mean Under ESSA?

The Every Student Succeeds Act (ESSA) defines “evidence-based” in Section 8101(21)(A) using a four-tier framework. Each tier represents a level of research rigor, and all four count as evidence-based for federal funding purposes.

A common misconception is that only Tier I programs qualify for evidence-based funding. That is not the case. Programs at all four tiers meet the ESSA evidence-based standard, though some competitive grants or state plans may specify a minimum tier. Check your specific funding source’s requirements before assuming Tier IV is sufficient.

For coaching programs, the evidence base is strong. Jim Knight’s work at the Instructional Coaching Group has helped establish coaching as a preferred form of professional learning, with his research showing that teachers who receive instructional coaching are significantly more likely to implement new practices compared to those who attend workshops alone. A meta-analysis of 60 causal studies published in Review of Educational Research found that coaching produced positive effects on both instruction quality (0.49 SD) and student achievement (0.18 SD), making it one of the most consistently effective professional development formats studied (Kraft, Blazar, & Hogan, 2018).

How Does Coaching Qualify as Evidence-Based Professional Development?

Instructional coaching has a deep research foundation. Knight’s Impact Cycle model and PEERS goals framework are used by thousands of schools nationally and are built on research into teacher learning, goal-setting, and reflective practice.

Beyond traditional coaching, newer approaches are adding to the evidence base. A 2023 study published in Nature’s Humanities and Social Sciences Communications found that teachers using video-based self-reflection improved in 11 of 14 professional competency areas, including lesson planning, classroom management, and student engagement. An earlier peer-reviewed study published by Emerald Publishing in 2015 found that technology-supported coaching enabled “more consistent and richer reflection on and communication about instruction” across teacher candidates, cooperating teachers, and university supervisors.

Program outcome data tells a similar story. The Arkansas Teacher Corps, which integrated video coaching into its teacher induction program, reported a 10-percentage-point increase in first-year teacher retention, a 650% increase in average coaching feedback per fellow, and growth on the Arkansas TESS rubric exceeding two standard deviations (Arkansas Teacher Corps, 2021). The program received the University of Arkansas Outstanding Team Award for these outcomes.

Research continues to expand. The University of Virginia and University at Albany, supported by a $1.4 million grant from the Bill and Melinda Gates Foundation, are currently studying how AI models can analyze classroom instruction and provide feedback to mathematics teachers as part of the AI for Advancing Instruction at Scale (AI2S) project.

Districts don’t need to wait for a multi-year RCT to meet ESSA requirements. A coaching program with a published research base, outcome data from implementation, and a logic model linking coaching activities to teacher and student outcomes can qualify at Tier III or IV today.

Where Does Coaching Fit in the MEGA Grant Structure?

The MEGA program would consolidate 17 education programs, including Title II-A (Supporting Effective Instruction), into a single $2 billion state block grant. The proposed structure creates three funding pathways, each with different requirements.

Pathway 1: Evidence-based literacy instruction (25% minimum). MEGA requires states to reserve at least 25% of the grant for “activities that advance, increase, expand, or focus on evidence-based literacy instruction.” That language is broad. Coaching that helps teachers implement evidence-based reading instruction, whether through Science of Reading coaching, guided self-reflection on literacy lessons, or structured feedback on reading instruction practices, fits within this mandate. Districts already investing in literacy coaching should document how their coaching activities align to this language.

Pathway 2: Evidence-based mathematics instruction (25% minimum). MEGA requires states to reserve at least 25% for “evidence-based mathematics instruction that provides students with meaningful learning experiences that promote strong core instruction, offer personalized and relevant learning opportunities, and support deep understanding of foundational and developmental mathematics concepts.” Read that description closely: “meaningful learning experiences,” “personalized learning opportunities,” and “deep understanding of foundational concepts” describe what coaching does. A coaching program focused on math instruction, where teachers reflect on their math lessons, receive feedback on their questioning and differentiation, and set goals around math-specific pedagogy, maps directly to this language. The University of Virginia and University at Albany, with $1.4 million in Gates Foundation funding, are currently studying exactly this application through the AI for Advancing Instruction at Scale (AI2S) project, which focuses on AI-powered feedback for mathematics teachers.

Pathway 3: Flexible professional development funding (remaining ~50%). The remaining MEGA funds can support any activities currently allowable under the 17 consolidated programs, including Title II-A. Title II-A has long funded coaching, mentoring, professional development, and activities that improve the effectiveness of teachers and school leaders. This is the most straightforward pathway for general coaching programs that are not content-specific.

Title I remains separate. Title I-A is level-funded at $18.4 billion and is not part of MEGA. Title I funds can still be used for professional development that supports teachers working with students from low-income backgrounds, providing an additional funding pathway for coaching in Title I schools.

The specifics will depend on your state’s plan and how it allocates MEGA funds across these pathways. Work with your state education agency to confirm allowable uses. But even before the final budget is set, districts can start documenting how their coaching investments align to the evidence-based literacy and math language above.

How to Build a Funding Case for Coaching

District leaders writing proposals or justifications for coaching investments under evidence-based funding requirements should address four areas:

1. Document the evidence tier. Identify the research supporting your chosen coaching program. Published peer-reviewed studies place a program at Tier III or above. A program with a strong logic model and a plan to measure outcomes qualifies at Tier IV. Collect citations, study summaries, and outcome data from the program provider.

2. Align to your state’s plan. Each state interprets ESSA’s evidence requirements differently. Some states maintain approved lists of evidence-based programs. Others accept any program that meets the tier definitions. Review your state’s ESSA plan and any guidance from your state education agency on evidence-based spending.

3. Calculate cost per teacher served. Funders want to see that professional development dollars reach teachers efficiently. Traditional one-on-one coaching typically costs $60,000 to $90,000 per coach position annually, with each coach serving 20 to 30 teachers. AI-powered coaching platforms can serve an entire building for approximately $3,500 per year, providing every teacher with on-demand access to coaching conversations. When budgets are constrained, this difference in per-teacher cost matters.

4. Plan for outcomes measurement. Even Tier IV programs need a plan to study their impact. Define what you will measure (teacher practice changes, retention, student outcomes), how you will collect data, and on what timeline. This strengthens your funding case and builds toward higher evidence tiers over time.

How AI Coaching Expands Access While Meeting Evidence Requirements

The core challenge for most districts is not whether coaching works. Research has established that clearly. The challenge is reaching every teacher who needs support when coaching capacity is limited and budgets are tight.

Traditional coaching models depend on having enough human coaches to serve every teacher. With typical coach-to-teacher ratios of 1:20 or higher, a building of 60 teachers might see each educator coached once a month at best. When funding consolidates or shrinks, coaching positions are often among the first budget lines to come under pressure.

AI-powered coaching changes this equation. Edthena’s AI Coach, recognized as a TIME Best Invention of 2025, provides on-demand coaching conversations available to every teacher in a building. Teachers engage in guided self-reflection using frameworks grounded in popular methodologies like Jim Knight’s evidence-based instructional coaching model. The platform doesn’t replace human coaches; it extends coaching capacity so that every teacher gets regular, structured professional learning, not just the few who have access to a dedicated coach.

For districts navigating evidence-based funding requirements, AI Coach builds on Edthena’s decade of peer-reviewed research on technology-supported coaching, applying those findings to AI-powered coaching conversations. The Gates Foundation-funded AI2S project at the University of Virginia is actively studying this approach for mathematics instruction.

At roughly $3,500 per building, it is also one of the most cost-effective ways to provide coaching at scale, a consideration that matters when programs like MEGA consolidate professional development funding into tighter overall allocations.

Frequently Asked Questions

What are the four ESSA evidence tiers for professional development?

ESSA defines four evidence tiers in Section 8101: Tier I (strong evidence from randomized controlled trials), Tier II (moderate evidence from quasi-experimental studies), Tier III (promising evidence from correlational studies), and Tier IV (demonstrates a rationale with a logic model and evaluation plan). All four tiers count as “evidence-based.”

How does coaching qualify under MEGA’s literacy and math mandates?

MEGA requires states to spend at least 25% of grant funds on evidence-based literacy instruction and 25% on evidence-based mathematics instruction. Coaching qualifies when it is explicitly focused on that content area. Literacy coaching (Science of Reading implementation, reading instruction feedback) aligns to the literacy mandate. Math coaching (feedback on math-specific pedagogy, questioning strategies, differentiation) aligns to the math mandate. The remaining ~50% of flexible funds inherits Title II-A allowable activities, which include general coaching and professional development.

How does AI coaching meet evidence-based requirements?

Edthena’s approach to technology-supported coaching is backed by peer-reviewed research published in Nature and Emerald journals, and by program outcome data from implementations like the Arkansas Teacher Corps. AI Coach builds on that research foundation, extending it with AI-powered coaching conversations grounded in the same evidence-based frameworks. The Gates-funded AI2S project at the University of Virginia is actively researching the AI-specific component, studying how AI models can provide feedback to mathematics teachers.

What documentation do districts need for evidence-based PD funding?

At minimum: citations to published research supporting the program, a logic model connecting activities to outcomes, a plan for measuring impact, and alignment to your state’s ESSA plan. Stronger applications include outcome data from prior implementations and cost-per-teacher analysis showing efficient use of funds.

How much does AI coaching cost compared to traditional coaching?

A dedicated instructional coach position typically costs $60,000 to $90,000 annually and serves 20 to 30 teachers. AI coaching platforms like Edthena’s AI Coach cost approximately $3,500 per building and provide on-demand coaching access to every teacher in that building.
