AI in Education: Personalised Learning and Automated Grading
How AI is changing UK classrooms in 2026 — personalised learning, automated grading, and the risks schools need to manage.
A Year 9 maths teacher in Leeds marked ninety essays last term without touching a single one by hand. An AI tool flagged the likely errors first. She just checked the flags and signed off. That’s the quiet shift happening across UK classrooms right now — faster than most parents realise, and further along than most head teachers admit in public.
What Personalised Learning Actually Means
Personalised learning isn’t new. Teachers have tried tailoring lessons to individual pupils for decades, usually by instinct and experience built up over years in a classroom. What’s changed is the tool doing the tailoring, and how fast it can react.
AI platforms now track how a pupil answers every single question. They spot patterns — which topics trip someone up, which explanations land, how fast a student moves through material compared to their peers. Then the next question adjusts automatically, without a teacher needing to intervene.
Ninestiles School in Birmingham piloted an adaptive maths platform in 2025. Pupils using it moved through the curriculum 23% faster than those working from standard worksheets, based on the school’s internal tracking. Not every trial shows numbers that clean, and results vary hugely between subjects.
Reading comprehension tools show smaller gains than maths platforms, oddly enough. Maths has clearer right and wrong answers for an AI to grade quickly. Judging the quality of a persuasive essay is a much harder problem, even for a well-trained model.
How Automated Grading Actually Works
Automated grading tools read full written answers now, not just multiple choice boxes. They compare a pupil’s response against a marking rubric, flag likely errors, and suggest a grade. A teacher still signs off before anything counts toward a final result.
The technology underneath is a large language model — the same family of tech powering ChatGPT or Claude. It’s trained to spot the difference between a genuine explanation and a lucky guess dressed up in the right words.
I looked into how accurate these tools actually are, and the numbers surprised me. Research adjacent to Ofqual from 2025 found AI graders agreed with human examiners on GCSE-style essays roughly 84% of the time. Close. Not close enough to remove the human check completely, though.
The disagreements cluster in specific places. Borderline grades — the difference between a 6 and a 7 — trip up AI graders far more than clear passes or clear fails. That’s exactly where human oversight matters most.
The UK Classroom Reality in 2026
Walk into most English secondary schools now and you’ll find at least one AI tool in daily use. Not because every teacher asked for it. Budget pressure pushed a lot of this adoption faster than pedagogy did.
Class sizes in England average 27 pupils at secondary level. Marking a full set of essays by hand can eat six or seven hours of a teacher’s week. AI tools cut that dramatically — some schools report a 60% reduction in total marking time.
That freed-up time doesn’t always go where you’d hope. Some teachers reinvest it in lesson planning. Others just get their evenings back for the first time in years. Both outcomes matter to the people living them, even if only one shows up in a school’s performance data.
Where AI Helps Teachers Most
Marking grabs the headlines, but it’s far from the only use case. Teachers increasingly lean on AI for:
- Drafting differentiated worksheets for mixed-ability classes
- Generating practice questions matched to a pupil’s specific weak spots
- Summarising long reading texts for pupils with SEN needs
- Flagging pupils falling behind before a formal intervention gets triggered
- Translating parent letters into different languages automatically
- Building revision quizzes straight from existing lesson slides
- Drafting individual pupil reports from a bank of observation notes
None of this replaces a teacher’s judgement. It strips out the admin load that keeps good teachers from actually teaching, which is usually the reason they took the job in the first place.
AI and Special Educational Needs
This is where the technology arguably matters most, and gets talked about least. Pupils with SEN often need material adapted in ways that take a teaching assistant real time to produce by hand, every single lesson.
AI tools can now simplify a text’s reading age instantly, add visual supports, or break a task into smaller steps — all without waiting for a specialist to free up. Several UK special schools reported measurable engagement gains after adopting these tools through 2025.
The catch: AI-generated adaptations still need a SENCO or specialist to check them. A tool trained mostly on mainstream curriculum content can misjudge what a specific pupil actually needs, especially for complex or overlapping needs.
Speech and language therapists have started using AI transcription tools to track a pupil’s progress over a term, spotting patterns a single weekly session might miss entirely.
The Risks: Bias, Data Privacy and Over-Reliance
Not everything about this shift is positive. Three problems keep surfacing in UK education research.
Bias comes first. If a grading model trained mostly on essays from native English speakers, it can mark down pupils writing in a second language — even when the content itself is correct. Several UK universities flagged exactly this issue during 2025 reviews.
Data privacy comes second. Pupil work often includes personal details, family circumstances, sometimes safeguarding information. Schools using cloud-based AI tools need to know precisely where that data travels and who can access it.
Over-reliance is the third, and the hardest to measure. If a pupil never wrestles with a genuinely hard problem because the AI smooths every path, do they actually build resilience? Teachers I’ve spoken with worry about this more than they worry about the technology failing outright.
The Cost of Getting This Wrong
A misjudged AI grade doesn’t just annoy a pupil. It can shape which set they’re placed in, which GCSE tier they sit, and ultimately which options stay open at sixth form.
Schools that rushed adoption without proper staff training saw the worst outcomes in early trials. A tool is only as good as the person checking its output, and rushed rollouts skipped that step more often than anyone would like to admit.
Cost matters too. Smaller schools with tighter budgets sometimes buy cheaper, less accurate tools than well-funded academies. That risks widening the exact attainment gap these tools were meant to close.
How the UK Compares Internationally
Estonia and Singapore both moved faster than the UK on national AI-in-education strategy, building centralised platforms every state school can access for free. The UK’s approach stayed deliberately fragmented by comparison.
That fragmentation has upsides and downsides. Individual schools can pick tools suited to their own pupils rather than a one-size-fits-all national system. It also means outcomes vary wildly between a well-resourced academy and a struggling comprehensive down the road.
Wales and Scotland are each piloting their own separate frameworks, adding another layer of inconsistency across the UK as a whole. A pupil’s experience of AI in the classroom now depends heavily on which side of a local authority boundary they happen to live on.
What Ofsted and the DfE Are Saying
The Department for Education published guidance in early 2026 encouraging “responsible AI adoption” in schools, stopping short of mandating specific tools. That’s deliberate — the DfE wants schools experimenting rather than locking into one national standard too early.
Ofsted hasn’t built AI use directly into its inspection framework yet. Inspectors do ask how schools safeguard pupil data when AI tools are involved, and that line of questioning is getting sharper with every inspection cycle.
UK investors keep asking about this because several EdTech firms building these tools are gearing up for funding rounds through 2026. Regulatory clarity — or the lack of it — shapes how fast that market can actually grow.
AI Tools UK Schools Are Actually Using
Century Tech, a UK-built adaptive learning platform, now runs in over 3,000 British schools. It adjusts content difficulty in real time based on how each pupil performs question by question.
Microsoft’s Copilot for Education has spread fast through secondary schools already running Microsoft 365, since it plugs straight into tools teachers already know how to use.
Smaller, subject-specific tools are growing too. No More Marking uses AI-assisted comparative judgement for English essays — pupils’ work gets compared pairwise rather than marked against a fixed rubric, which research suggests produces fairer results across different writing styles.
What This Means for You
If you’re a parent, ask your child’s school what AI tools they use and exactly how pupil data gets protected. Most schools have a written policy — ask to see it directly rather than accepting a vague reassurance.
If you’re a teacher, treat AI grading as a first draft, never a final word. That 16% gap between AI and human judgement still matters enormously on results day, and borderline grades deserve extra scrutiny.
This shift isn’t slowing down anytime soon. Schools that get the balance right — AI for admin, humans for judgement — will likely see the strongest outcomes for pupils over the next few years.
