What did the DfE's June 2026 EdTech report actually find?
Assessment technology is the fastest-growing corner of UK EdTech, expanding at 18.1% a year. That is the most consequential finding buried in the DfE's June 2026 EdTech market assessment, Assessment of the education technology market in England — and it is a more useful signal than the headline £6.5bn the report puts on the sector overall. EdTech (education technology — the use of technology to support and enhance education) in England is now a sizeable industry: the DfE counts 1,123 companies employing between 29,660 and 39,100 people, growing at an average of 8.8% a year and pulling in roughly £782m in annual investment.
The DfE breaks that market into seven verticals. Assessment technology is the smallest by company count but, at 18.1% growth, comfortably the fastest-moving — more than double the sector average. The table below shows where it sits against the rest of the market.
| Vertical | Companies | Turnover | Annual growth | Investment |
|---|---|---|---|---|
| Assessment | 71 | £470m | 18.1% (highest) | £24.3m |
| Personalised learning | 74 | £77m | 3.1% (lowest) | £187m |
| Management & admin | 148 | £1.39bn | — | £219m |
| Foundational learning | 446 | £2.6bn | — | — |
| Hardware | 390 | £2.48bn | 8.8% | — |
| Immersive | 215 | £287m | — | £158m |
| Assistive | 80 | £96m | — | £8.6m |
All figures above are drawn from the DfE's June 2026 report (p.7–8). One caveat is worth holding in mind throughout: the DfE is unusually candid that the demand-side picture is incomplete.
Why is assessment technology growing so fast?
The short answer is that the growth is demand-led, not investment-led. The DfE is explicit about the driver, and it is not the usual venture-capital story.
Workload has become the new return-on-investment currency for schools, and assessment is where that pressure concentrates. Marking and feedback are among the heaviest, most repetitive demands on teacher time — the DfE Teachers' Workload Survey and TALIS 2018 data put the marking burden at well over eight hours a week for many teachers. A tool that returns that time is a benefit every senior leadership team can immediately quantify, which is exactly why uptake is moving faster here than anywhere else in EdTech.
There is also a post-pandemic legacy at work. Years of disrupted exams, teacher-assessed grades and uncertainty around standards left schools acutely aware of how much hangs on assessment — and how fragile and labour-intensive their existing processes are. That awareness has translated into a willingness to adopt tools that make assessment faster, more consistent and easier to evidence. The DfE notes that classroom and assessment tools represent the second-highest area of engagement among the products it examined.
What's the gap between investment and demand telling us?
The most revealing number in the whole report is a comparison. Assessment technology generates £470m in turnover but attracts only £24.3m in annual investment, according to the DfE (June 2026, p.8). Personalised learning shows the mirror image: £187m of investment chasing just £77m in turnover. In other words, the vertical schools are buying most eagerly is the one investors are funding least — and the vertical investors are betting heavily on is the one schools are buying least.
That divergence matters. It suggests investors are pricing in a different future than the one schools are buying today: a long-horizon bet on adaptive, personalised learning platforms, even as immediate budgets flow towards workload-reducing assessment tools. For a market watcher, the read is that assessment is a vertical with proven demand but comparatively thin capital — which historically is where the most room to mature, and the most opportunity, tends to sit.
What should MAT leaders take from this?
For a multi-academy trust (MAT — a group of schools run under a single legal and governance structure), the report offers three practical implications for procurement strategy in 2026–27.
- Prioritise the workload case. If a tool measurably returns teacher time on marking and feedback, it sits in the part of the market the DfE identifies as growing fastest — and the business case is the one your staff will feel most directly. Lead procurement conversations with hours saved, not features.
- Favour the specialised over the general. The DfE expects investment to shift towards specialised AI solutions, warning that general-purpose AI may reduce the competitive advantage of legacy platforms. A purpose-built marking tool that knows your exam boards will usually outperform a generic GenAI assistant for assessment-specific work — a distinction worth weighing carefully when you compare specialised and general-purpose AI for education.
- Expect a young, fast-moving field. With high growth but thin investment, assessment technology is maturing quickly. Procure with pilots, clear exit terms and proper evaluation rather than long lock-ins, because the competitive landscape will keep shifting.
Newer entrants like the UK-built ReMarkAble AI, which marks student work against AQA, Edexcel, OCR and WJEC mark schemes, are examples of the specialised, workload-reducing assessment tools the report identifies as the fastest-growing segment of the market.
What's next for the sector?
The policy backdrop is starting to catch up with the market. The DfE frames adoption around eight stages of EdTech implementation and identifies four system-level constraints holding schools back: strategic capability gaps; resource and prioritisation pressures; procurement and infrastructure constraints; and sustained adoption and impact measurement. Initiatives such as the EdTech Testbed and a developing evidence base are intended to address that last constraint — the persistent gap in reliable evidence on how these tools perform in real classrooms.
For school leaders, the implication is straightforward: the demand signal is clear, the policy scaffolding is being built, and the part of EdTech most directly addressing teacher workload is also the part with the most room to grow. The schools that approach assessment technology deliberately now — piloting, measuring and choosing specialised tools over generic ones — will be best placed as the vertical matures.

Frequently Asked Questions
What is the fastest-growing EdTech vertical in the UK?
Assessment technology is the fastest-growing vertical in UK EdTech, according to the DfE's June 2026 EdTech market assessment, Assessment of the education technology market in England. The report puts assessment growth at 18.1% a year — more than double the 8.8% sector-wide average. This covers the 71 UK companies building tools for marking, feedback, exam preparation and progress tracking. The DfE attributes the surge to immediate school demand to reduce workload and improve efficiency, rather than to a wave of investor capital.
How big is the UK EdTech market in 2026?
The DfE's June 2026 EdTech market assessment counts 1,123 EdTech companies in England, employing between 29,660 and 39,100 people and generating around £6.5bn in annual turnover. The sector grows at an average of 8.8% a year and attracts roughly £782m in annual investment. EdTech here means technology used to support and enhance education — products designed to improve the learning experience for pupils, reduce workload for staff, and improve the efficiency of operations. The market spans seven verticals, from foundational learning to assistive technology.
What did the DfE's 2026 EdTech report say about AI?
The DfE's June 2026 report records rapid uptake of general-purpose generative AI (GenAI) platforms such as ChatGPT and Claude for lesson planning and administration. Crucially, it also signals a shift: it expects investment to move towards specialised AI solutions, warning that general-purpose AI may reduce the competitive advantage of legacy platforms. In other words, the report distinguishes between broad GenAI assistants teachers reach for informally and purpose-built tools designed for specific educational jobs like marking. The assessment vertical sits squarely in that specialised category.
Why are schools buying assessment technology faster than other EdTech?
Schools are buying assessment technology faster than other EdTech because it targets the single biggest drain on teacher time: marking and feedback. The DfE's June 2026 report describes assessment growth as driven by immediate school demand to reduce workload and improve efficiency. Marking is a concrete, recurring cost that every school understands, so the return on investment is easy to see. By contrast, verticals like personalised learning offer more diffuse, longer-horizon benefits, which is reflected in their much slower growth of 3.1%.
Who wrote the 2026 DfE EdTech report?
The report, Assessment of the education technology market in England, was published by the Department for Education (DfE) in June 2026. It is a market assessment commissioned to map the size, shape and growth dynamics of the EdTech sector serving English schools and colleges. The DfE itself notes a key caveat in the report: reliable evidence on how EdTech is actually used in practice in schools and colleges remains limited. So while the market sizing is robust, the report is candid that classroom usage data is still maturing.
