Illinois districts are sitting on one of the most sophisticated school funding frameworks in the country, and many of them still aren’t sure how tutoring fits into it. The Evidence-Based Funding formula was built around the idea that adequacy and equity require specific, research-backed investments in students. High-impact tutoring is one of those investments. The gap, for most districts, is figuring out how to connect those two things in practice.
What the Evidence-Based Funding Formula Actually Funds
Illinois’s Evidence-Based Funding model, signed into law in 2017, distributes state education dollars based on a district’s distance from an “adequacy target” calculated using 27 evidence-based elements. These elements were drawn from research on what resources schools need to reach student achievement goals, ranging from staffing ratios to extended learning time to student support services.
Tutoring does not appear as a standalone line item in the formula. What the formula does is generate funding directed toward the resource categories that tutoring falls under: intervention supports, extended learning, and differentiated staffing. Districts that receive EBF increases have flexibility in how they deploy those dollars, provided the spending traces back to strategies with a research base.
That’s where the alignment question gets practical. ISBE’s research brief on the EBF model notes that the formula’s adequacy elements are grounded in the assumption that districts will use resources on interventions with demonstrated effectiveness. High-impact tutoring, particularly structured small-group and one-to-one models, satisfies that assumption.
How the Illinois Tutoring Initiative Demonstrated the Connection
The Illinois Tutoring Initiative, launched with federal American Rescue Plan funding and administered through ISBE, gave the state a real-world test of what high-impact tutoring looks like when deployed at scale. By the time the federal grant period concluded in late 2024, the initiative had supported student learning across dozens of districts, with documented gains in reading and math.
Illinois State University’s reporting on the initiative’s conclusion noted measurable academic improvement among participating students, particularly in literacy. A 2024 AERA-presented study using data from the initiative found positive achievement effects, with results suggesting that in-school tutoring models outperformed alternatives that depended on voluntary after-school attendance.
The initiative’s structure also clarified something important for district finance offices: high-impact tutoring can be documented, evaluated, and reported in ways that satisfy federal and state accountability requirements. That’s not incidental to the funding question; it’s central to it.
Where EBF Dollars and Tutoring Spending Actually Intersect
The coverage gap in most policy discussions is the practical one: how do EBF increases actually get from the state allocation to a tutoring program? The path is less direct than many districts assume, but it exists.
Districts receiving EBF funds that push them closer to adequacy targets are expected to prioritize high-need students and evidence-based strategies. ISBE guidance has consistently pointed toward interventions with strong research backing as appropriate uses of adequacy-driven funding. For districts with significant populations of students performing below grade level, high-impact tutoring falls squarely within that framing.
Several additional funding pathways run parallel to EBF and are commonly used alongside it:
- Title I set-asides for schoolwide or targeted assistance programs, which can fund tutoring for low-income students when the program meets evidence standards
- Title III allocations for English learner support, relevant for districts where tutoring is deployed with ELL populations
- State literacy and reading improvement grants, which ISBE has administered in connection with Illinois’s evidence-based reading instruction requirements
The University of Illinois at Chicago’s Institute of Government and Public Affairs has noted that EBF was designed to work alongside federal funding streams, not replace them. Districts that are building tutoring programs with sustainable footing are typically braiding these sources rather than relying on any single one.
What “Evidence-Based” Means When It Comes to Program Selection
The EBF formula’s emphasis on evidence-based elements isn’t a philosophical stance. For districts using EBF-adjacent funds to pay for tutoring, program selection carries real accountability implications.
Federal ESSA evidence tiers provide the most commonly referenced framework. Programs that meet Tier 1 (strong evidence), Tier 2 (moderate evidence), or Tier 3 (promising evidence) standards are generally considered appropriate for use with Title I and Title III dollars, and alignment to these tiers also supports the logic of spending EBF dollars on a given program. A 2024 University of Chicago Education Lab study found that in-school tutoring programs broadly demonstrated positive effects on student learning, adding to the research base supporting the category.
For district administrators navigating procurement or preparing for compliance reviews, the practical question is whether the program selected has independent research behind it, not self-reported outcome data. ESSA evidence documentation and third-party evaluation reports are the forms of evidence that hold up in audit conversations.
Implementation Variables That Affect Both Outcomes and Compliance
Dosage, scheduling, and staffing are not delivery questions alone. They’re also the factors most likely to determine whether a tutoring program produces the results that justify its cost and whether district documentation holds up to scrutiny.
Research on high-impact tutoring, including studies drawn from the Illinois Tutoring Initiative’s experience, points toward a few consistent parameters: sessions of sufficient frequency (typically multiple times per week), small group sizes (one-to-three or one-to-one), and instructor qualifications that include content knowledge and training in structured instructional approaches.
Rural districts in Illinois face a distinct version of this challenge. Staffing a consistent, credentialed tutoring program is harder when the labor pool is smaller and transportation logistics compound scheduling difficulties. The ITI’s statewide rollout surfaced these implementation variations, and they remain a real consideration for districts evaluating program models. In-school scheduling, where tutoring is built into the school day rather than appended after it, addresses the attendance problem directly and tends to produce more complete participation data, which matters for program documentation.
What Illinois Districts Should Be Asking Before the Next Budget Cycle
The EBF model is entering its eighth year of implementation. Adequacy targets are still out of reach for many districts, particularly those serving high concentrations of low-income students, but the formula continues to direct incremental increases toward those gaps. For district leaders planning tutoring investments, the budget cycle question is less “can we afford this” and more “how do we document this correctly and sustain it beyond one-time funding.”
A few questions worth pressure-testing before committing to a program or a funding strategy:
- Does the tutoring program have independent ESSA-tier evidence, or is the research base proprietary?
- Is the program structure consistent with the dosage and frequency parameters that the research supports?
- Are the funding sources being braided in a way that can withstand an audit, with clear documentation of allowable use for each stream?
- Is the scheduling model one that produces reliable attendance data, or does it depend on variables outside the district’s control?
The districts that are getting this right are not treating tutoring as a line item. They’re treating it as an intervention strategy with a funding logic attached, and they’re building the documentation from the start rather than retroactively.
Illinois has done the work of building a formula that points toward evidence. The districts that benefit most are the ones that take that framing seriously when they’re deciding how to spend what the formula delivers.
