What districts paid, and what it bought.

The consolidation decision is being made blind.

Sixty-one percent of school districts expect to consolidate spending with fewer vendors now that federal stimulus money is gone.¹ Every one of those decisions rests on a question that sounds simple: which of our vendors has a record worth keeping?

Nobody can answer it. Not because the answer is hard, but because the record does not exist in one place. What a district paid its vendors sits in a procurement system. How its students performed sits in an assessment file. In most states, no person and no institution has ever put the two side by side. Renewal decisions run on relationships, inertia, and memory.

The Ledger exists to close that gap. It is a reconstruction of the vendor spending record from state disclosure systems, joined to the public record of student outcomes, at the level where decisions are actually made: the individual district, year by year.

This first issue resolves one state completely. Maryland publishes sixteen consecutive fiscal years of vendor payments for all twenty-four of its school systems. We matched every payment line to a master vendor registry, paired the result with sixteen years of independently measured reading and math outcomes, and put both on a single timeline. Every number in this report traces back to a public source file and can be reproduced on demand.

Every dollar now has to defend itself.

The market context is not in dispute, because the most-read research in the sector has already established it. McKinsey's September 2025 survey of 386 district leaders found total K-12 funding flat at roughly $969 billion while inflation erodes real spending power, federal funding down 22 percent (a $24 billion loss) as ESSER expires, and 34 states facing enrollment declines through 2031.¹

The same survey describes where the pressure lands. Supplemental curriculum, tutoring, assessment, and professional development sit in the categories most vulnerable to cuts. Districts told McKinsey they are "focusing on getting the core curriculum right" because they "no longer have the funds for as many supplemental curricula." And the federal picture adds a structural threat: the proposed K-12 Simplified Funding Program would collapse 18 federal grant programs into a single block grant, a $4.5 billion reduction that would also scramble the program-level signals the market uses to read district budgets.¹

The conversation is global. McKinsey's April 2026 report with the International Education Funders Group frames the same question for education philanthropy: not just more capital, but "improving the effectiveness of existing capital."² From federal block grants to global aid, education finance in 2026 has converged on one question: what did the money actually buy?

McKinsey closes its district survey with advice we agree with completely: districts should concentrate spending on "the highest-quality external providers that offer solid evidence of their results." What that advice needs, and what a survey cannot supply, is the instrument: the record of what each district paid each vendor, next to what happened. That record is what follows.

Maryland, resolved.

Maryland is the first state where the full record can be put on one timeline: every school system, every disclosed vendor payment, every year of measured outcomes, sixteen years deep.

Start with the wallet. Over sixteen fiscal years, Maryland's 24 school systems disclosed just over one billion dollars in payments to the named instructional and assessment vendors in PILLAR's vendor registry: core curriculum publishers, supplemental and intervention providers, and assessment companies. Exhibit 1 shows the ten largest. Identities are de-identified in this public edition and available, named, inside PILLAR Vertical Intelligence.

Now the flagship question. Take the single largest family on that chart: a top-three literacy and core-curriculum incumbent, present in the Maryland record in all sixteen fiscal years, paid by 21 of the state's 24 school systems, $128 million in disclosed payments. Put that spending on a timeline. Under it, put the state's reading outcomes for grades 3 through 6 on Stanford's national scale, where zero is the national reference point.

Read the shape, not a verdict. Payments to this incumbent step up around the state's curriculum transitions in the mid-2010s, surge through the stimulus years, and reach their highest levels in FY2024 and FY2025, after outcomes had settled well below where they started. Over the same sixteen years, Maryland reading moved from clearly above the national reference (+0.17 at its 2011 peak) to clearly below it (−0.10 in 2025). Math moved further, from +0.19 to −0.20.

The finding is not that any vendor failed. The finding is that a district could pay one vendor family for sixteen consecutive years, through three renewal cycles and one historic decline in outcomes, without anyone on either side of the transaction ever seeing this chart. The villain is the disconnection.

A statewide chart can hide as much as it shows, so The Ledger's standard is to work at least one district completely. Montgomery County is Maryland's largest system, around 160,000 students, and one of only two systems whose disclosure record covers all sixteen years. Its full ledger against this incumbent:

The stimulus ratchet, in actual dollars.

Survey research says supplemental programs sit first in line for cuts. The checkbook shows what that means in dollars, and it has already begun.

Splitting Maryland's named instructional spend into three market categories tells the story of the last five budget cycles. Supplemental and intervention spending septupled from its pre-stimulus level to a $77 million peak in FY2022, then fell 45 percent in three years. Core curriculum spending held, then hit a sixteen-year high of $92 million in FY2025 as systems concentrated their remaining dollars, exactly the "get the core right" behavior district leaders described to McKinsey.

For every vendor whose revenue lives in that middle band, this chart is the next three years of pipeline reality. For every district leader, it is a reminder that the cuts are not hypothetical, and that what survives them should be chosen on the record rather than by which contract renews first.

Renewal as a decision, not a reflex.

This report was written for the administrator first. The record it reconstructs is your record, and it changes what you can ask.

A superintendent or chief academic officer holding this ledger can put three questions on the table that were previously unanswerable:

What have we actually paid this vendor, in total, over its full tenure? Not this year's license fee. The sixteen-year figure, which in Maryland runs to eight digits for a single family in a single mid-sized system, changes the seriousness of the renewal conversation.

What moved while we paid it? Not "did the vendor cause it," which no fair reading of this data can answer. Simply: over the tenure of this incumbent, did the outcomes we bought it to improve go up or down? If the answer is down for sixteen consecutive years, the burden of evidence in the renewal meeting should shift.

What would we expect a challenger to show? The same chart. Any vendor asking to displace an incumbent should be asked to show its own spend-and-outcome record from districts it already serves. The data to check the claim now exists.

None of this requires a district to buy anything. Maryland's disclosure files are public. SEDA is public. What PILLAR adds is the reconstruction: the master vendor registry that recognizes all 30 spellings of one company's name as one company, the exact district matching, and the standing analyses that keep the record current. The methodology section at the end of this issue is complete enough to check our work.

Consolidation favors whoever can show a record.

If 61 percent of districts consolidate vendors, the winners will be decided by evidence or by inertia. Vendors should prefer evidence, because inertia favors nobody's best product.

The Maryland ledger holds three lessons for the companies serving this market:

Incumbency is measurable now. The flagship incumbent's position, sixteen consecutive years, 21 of 24 systems, is visible in public data. So is everyone else's. Footprint claims, tenure claims, and "trusted by" claims are checkable, which means they are also provable for vendors whose record is real.

The record is a defense as much as an exposure. A vendor whose districts show durable results has, for the first time, third-party public evidence to bring to a consolidation review. The same chart that indicts inertia can defend a product that works. The record cuts both ways, which is what makes it credible.

The cut zone is mapped. Exhibit 4 is the revenue outlook for the supplemental and intervention category, drawn from disclosures rather than surveys. Vendors in that band have roughly one renewal cycle to attach evidence to their contracts.

Vendor identities are de-identified throughout this public edition. Inside PILLAR Vertical Intelligence, the same analyses return named vendors, district by district, year by year, with the full payment trail. That is deliberate: the public record belongs in public, and the competitive detail belongs to the people doing the work of serving districts well.

How much of the record exists yet.

The Ledger's recurring commitment: each quarter, this index reports how much of the national spend-to-outcome record has been reconstructed, and what remains structurally out of reach.

Reconstruction depends on what states choose to disclose. Six states currently publish district-level vendor payments in usable form. Maryland is the deepest and is fully resolved as of this issue. Utah is next: thirteen years, every district and charter, $26.7 billion, queued as the flagship of Issue No. 002.

One more trajectory belongs in this issue, because it anchors the outcome side of everything above:

How this was built, and what it cannot say.

The Ledger's only durable asset is that its numbers are true and checkable. This section is therefore the most important one in the report.

1. Correlational, not causal. Spend and outcomes are placed on a shared timeline. Nothing in this data isolates any vendor's causal contribution, and no exhibit or sentence in this report claims otherwise. The correct reading is always: outcomes moved X over the period during which Y was the recorded incumbent.
2. Disclosure floors. Maryland discloses payments of $25,000 and above; totals are floors. Utah applies a $1,000 threshold and masks payroll pseudo-vendors. An empty cell means no disclosed payment, not zero dollars.
3. Vendor families are corporate entities. The flagship family aggregates 30 payee spellings including a consulting division and a post-2023 acquisition. The Ledger traces companies, not individual product lines, and says so wherever it matters.
4. First year of record is not selection year. A vendor's first appearance is bounded by each system's disclosure start. Twenty of Maryland's 24 systems enter the record in FY2018–19; only Montgomery and Howard County span all sixteen years individually. Statewide claims use the statewide record; single-district claims use only full-span districts.
5. Outcome gaps are shown, not smoothed. No statewide testing occurred in 2020–21, and Maryland's assessment transitions create gaps at 2014 (partial) and 2018. Lines break at every gap. Grades 3–6 are used because Maryland's grade 7–8 math series is structurally truncated by middle-school algebra course-taking.
6. Matching is exact and documented. Districts are identified by their official federal identifiers through a published reference table (24 of 24 Maryland systems, no ambiguous cases). Vendor names resolve through a documented list of 75 reviewed matching rules; every match records which rule made it. Payments that cannot be matched with certainty are excluded and counted, never guessed.
7. Everything can be reproduced. Each exhibit carries a reference number tied to a saved analysis in PILLAR Vertical Intelligence. The same figures are live in the PILLAR product and were verified against this issue on July 23, 2026. Issue No. 002 repeats and extends this work rather than rebuilding it.
8. What we will not do. No estimated or interpolated figures, no filling gaps with outside guesses, no named vendors in public editions, and no survey data presented as records. Where the record does not exist, the coverage index says so.
