Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The estimate is built upward from the number of standardized and formative tests administered per enrolled K-12 student each year, multiplied by the realized per-test or per-license price charged by assessment providers across paper-based, digital and adaptive delivery formats. Enrollment figures, testing-frequency norms set by state accountability calendars, and per-student licensing rates for formative and diagnostic platforms form the core inputs. This bottom-up build is then checked against disclosed segment revenue from publicly traded education companies and against state procurement contract values where available. Where the two diverge, the bottom-up assumption, usually testing frequency or per-license pricing, is revisited and corrected rather than the disclosed revenue being discounted to fit.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary research targets curriculum directors and assessment coordinators at school districts, state education agency testing officials, and product and pricing leads at assessment publishers, since these roles set the purchasing criteria, testing calendars and contract terms that determine realized volumes and prices. Procurement officers within district and state purchasing offices are included to confirm contract renewal cycles and typical price bands paid for summative, formative and diagnostic products. Sampling emphasizes the United States, where state-level accountability testing sets the largest share of demand, alongside the United Kingdom and Australia for internationally benchmarked assessment programs, and India and China for platforms serving large, fast-growing school populations.

Secondary sources, this report

Desk research draws on published state education agency assessment calendars and per-pupil testing budget disclosures, U.S. Department of Education Common Core of Data enrollment figures, and NCES survey releases on technology use in schools. Company-level inputs come from the segment disclosures of publicly traded education and assessment publishers, including Pearson's and Houghton Mifflin Harcourt's own reported education-services revenue. State procurement portals and school board meeting records provide contract award values for summative testing vendors. International inputs draw on OECD education-at-a-glance enrollment statistics and Cambridge International's published syllabus and assessment uptake reports for benchmarking outside the United States.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is anchored to state accountability testing schedules already legislated or announced through 2027, projected enrollment trends by grade band, and the pace at which remaining paper-based testing programs convert to digital or adaptive delivery. Pricing is assumed to hold roughly flat in real terms for summative testing, with formative and diagnostic products carrying a modest premium as adaptive scoring features are added. The forecast normalizes for the post-pandemic rebound in testing volumes recorded through 2022, treating 2023 onward as the more representative growth baseline. For the forecast to hold, states must maintain current testing-frequency mandates and school enrollment must not decline materially in the largest markets.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Outputs were back-tested against recorded year-over-year growth in disclosed education-assessment segment revenue from 2020 through 2024 to confirm the historical build tracks actual reported results within a reasonable margin. Segment-level shifts, particularly the pace of formative and adaptive-platform growth relative to summative testing, were reviewed against publicly reported product-mix commentary from assessment publishers. Sensitivities were tested on enrollment growth, testing-frequency assumptions, and the digital-conversion rate for the delivery-mode split, to confirm the forecast is not overly dependent on a single input. Regional splits were checked against enrollment and public-education-spending patterns reported by national statistics agencies in each region.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is strongest for United States summative testing volumes and pricing, where state contract values and enrollment data are both well documented and cross-checked. It is weaker for formative and diagnostic product revenue outside large publicly traded vendors, where pricing is often bundled into broader curriculum licenses and not separately disclosed. Confidence is also lower for Latin America and Middle East and Africa, where testing-frequency norms and per-student spending are less consistently reported. A material change in state testing mandates, or a faster-than-expected shift away from standardized summative testing, would be the clearest trigger for revising this estimate.
