Two extraordinary charts from today’s PISA test results: 1) School test scores continue to collapse internationally, underscoring how this is no longer a Covid effect but sustained decline. Those falls in reading and maths are equivalent to about two years of lost schooling.

2) England is a rare exception. During the 2010s many other countries (including the other 3 UK nations) changed tack, experimenting with ideas like transferrable skills instead of focusing on tried-and-tested disciplines and methods. It looks like those experiments have failed.

Great thread from @daisychristo here too
The PISA 2025 results are out today. Some quick insights. - The major story is very significant global decline. The last PISA study was in 2022, and saw big declines in reading and maths scores from 2018. Obviously the pandemic played a part. - But this 2025 round has seen further falls even from the 2022 lows! Things haven't gone back to normal post-pandemic - they've got worse. Every generation thinks the generation below is less smart - but this time they might be right!

As I see it, the deluge of digital distractions is eroding people’s capacity to focus and think for extended periods of time, making strict structures and proven methods especially important for education. Full piece here: ft.com/content/a8016c64-63b7…

Imagine being the global leader in education and spitefully sticking a punitive VAT onto your best industry, intentionally hobbling it purely for the vibes, and adding friction to the thing you are best at.

England might be exceptionally good at fudging the numbers by undercounting weak students.
1/3 The UK’s PISA resilience amid falling OECD scores likely reflect long-standing sampling bias. Jerrim (2021) compared England’s 2018 PISA (peak math& reading score) sample with national GCSE results and found weaker pupils underrepresentedeven after official weighting. doi.org/10.1002/rev3.3270

Why say Scotland education has ‘failed’, based on a selective few PISA scores? OECD say you are wrong. They say ‘Scotland better at ‘social and emotional’ scores.👇 Why not report that? youtu.be/xA_8MMsRnY0

My 🏴󠁧󠁢󠁥󠁮󠁧󠁿 daughter is at a 🏴󠁧󠁢󠁳󠁣󠁴󠁿 university. She found the first year easy because the curriculum had to allow for the 🏴󠁧󠁢󠁳󠁣󠁴󠁿 students to catch up. A Levels seem to be more academically rigorous than Highers.

How much of the decline then could be attributed to the pisa test not being compatible with these new teaching approaches?

That’s so limiting and offers zero evidence of success post school. If it’s measuring the amount reaching University, well that hasn’t changed significantly in the recent times. I believe schools should help prepare for life post school with emphasis on skills and knowledge

Of course, what’s missing from these types of studies is any context asking what’s the purpose of education in the 21st century. I know its purpose for the 19th and early 20tg centuries but in 2026, how does one arrive at educational success? If it’s simply attainment then 1/2

The results for the UK are factitious. The UK is afflicted with atrocious exam boards, and fewer students are engaging with English, the most important subject. That is one aspect of my warning about these worthless “literacy assessment” style tests. Not only are they not teaching tools as they need to be to avoid crippling opportunity costs, they are also masking severe underperformance as in the UK. Another factor leading to chaos in the UK is the massive, absurd 11-month teacher education programs, as at UCL. You can’t coin a teacher proficient in a curriculum in that short period of time. It takes a minimum of two years with extensive professional development. National testing has to be based on a precise national curriculum. You have to teach these texts minutely, page by page, reading out loud, in teacher education programs and in schools: Romeo and Juliet (Cambridge School Shakespeare) Macbeth (Cambridge School Shakespeare) Othello (Cambridge School Shakespeare) King Lear (Cambridge School Shakespeare) Hamlet (Cambridge School Shakespeare) Shakespeare’s Sonnets (Poetry Foundation): 1, 15, 18, 30, 33, 60, 64, 65, 73, 97, 98, 104, 116, 129, 130.

Amazing things can happen provided you exclude enough data.
The 2018 sampling PISA sampling bias has likely become far worse since. England missed PISA participation standards in 2022. The OECD estimated scores could still be around 8 points too high in maths and 7 in reading, even after statistical weighting. OECD analysis In 2025, England met participation targets. But exclusions across the UK excluding Scotland reached 7.6%, up from 4.9% in 2022 and above the 5% standard. Among matched pupils in participating English schools, 40% of non-participants had been eligible for free school meals, versus 24% of participants. Special educational needs support: 25% versus 11%. Weighting barely changed these imbalances. assets.publishing.service.go…

Avoiding this is only half the story. The other story is that England failed to close the gap on leading nations like Singapore and England's results are basically over twenty years

Isn't it the case that cross country comparisons don't give a true account as selection of schools/pupils differ eg England selects small number of quality schools, other countries, Scotland included, use larger and more representative samples?

England’s PISA results are stronger than Wales’s. But are we comparing like with like? England educates more pupils with significant difficulties outside mainstream schools, while Wales is more inclusive. How much of the gap is education, and how much sample composition?
