Solving marking at scale! The AI and assessment state of play, February 2026

How long does it take you to mark a set of essays?

With our new AI system it takes 10-15 minutes - but you will still see every essay twice.

If you’re curious about how it works, book a call with me and I’ll set you up with 30 free credits to try it out.

People worry that AI means removing human expertise.

Our AI assessment system retains human oversight of every essay & builds in real human feedback.

It is also incredibly efficient!

To give it a go, you can join an intro webinar or book a call with me.

PGMOL admits VAR offside error to disallow Diaz goal PGMOL has admitted that Luis Díaz had a goal incorrectly ruled out for offside in Liverpool's 2-1 defeat at Tottenham Hotspur on Saturday.

How do you feel when huge games are ruined by bad VAR calls?

We’ve written a lot about using AI to mark.

But what about using AI coding tools to develop our website? Do they work? Can you vibe code a complex website?

Our CEO & CTO have had some disagreements, outlined in this post!

We've just published the results of our first AI-enhanced Comparative Judgement assessment in Australia.

It worked really well! The human & AI judges agreed with each other!

We've emailed participating schools with results. Join one of our webinars to find out more.

Seeing how @daisychristo.bsky.social and NMM's work on this has developed is facinating. Having had to delve into the Ed/AI world more lately, it's clear how valuable it is to have this research being led by people who know how learning works and have a healthy scepticism.

We have been sceptical about AI marking in the past, & there are still issues to iron out.

But we now have a system that is working well in practice. If you went back in time and offered this to someone in the past, they'd think it was a kind of magic.

Tutor-proof tests: nice idea, but for high-stakes tests that determine entry into prestigious institutions, they won’t work.

Is it possible to develop a tutor-proof test? Or should we focus on tests worth teaching to instead?

Selective schools & universities use entrance tests.

Can you create an entrance test that is "tutor-proof"? Would you even want to?

Are non-verbal reasoning tests the answer?

Does a university education help you earn more? Maybe, but not in the way you think

A great provocation from @daisychristo.bsky.social at the end of this! Standardised assessments for universities….

Read the blog before you say this is bonkers!

Why do we measure the impact of university based on graduate earnings?

Would you measure a hospital based on the later earnings of the people it treats?

Why not use assessment data to measure university impact instead?

We spend billions of private & public money on university education, justified by the fact that it teaches valuable skills.

But there's surprisingly little evidence this is true - partly because we have little reliable assessment data for most degrees.

Lots of overlap between this post and my @smfthinktank.bsky.social paper from 2021 on how policymakers should respond to the problem of signalling in education.

Specifically on the need for better measures of direct "learning gain" from university

Student loans & interest charges are high, but justified by the fact graduates earn more.

But does that justification work? People who buy Rolexes earn more than those who don't, but we don't encourage 18-year-olds to take out loans to buy one..

We've got some feedback on our AI feedback.

It's "uncannily accurate" - but maybe a bit too verbose and harsh! We're working on simplifying and softening it.

Imagine a world where English teachers get their marking done before the maths teachers...
That is what our pioneer schools are seeing!
