Six weeks off produces a measurable slide, and it hits some children much harder than others. The reading-score evidence Gladwell cites shows all income groups gain during term, but only the better-off keep gaining over the summer - the gap opens in the holidays, not the classroom. The fix is small and regular: reading most days and a little maths, not a summer school.
For context: 62% of pupils in England met the expected standard in reading, writing and maths at key stage 2 in 2025, up from 61% in 2024. — DfE, Key stage 2 attainment, 2025
What is the summer gap?
The long-awaited Summer holidays are coming up. A period for rest and relaxation of course, but don't get too comfortable or you may just end up harming your education in the long term.
Malcolm Gladwell, who I have discussed before, uses reading scores from nursery to fourth grade to show that low, middle and high-income children all gain academically during the school year. It’s in fact the summer months where the achievement gap occurs. Yes, you read that right. The summer months are the major culprits.
Focusing on just the summers, Gladwell shows that low-income children experience a net loss in education when we add up the summers. By contrast, middle and high-income children continue to gain in reading over the summer.
Suddenly one of the causes of Asian math superiority also becomes even more obvious. Students in Asian schools don't have long summer vacations. The school year in the UK, on average, is 190 days long.
The South Korean school year is 220 days long. The Japanese school year is 243 days long. {Excerpt from Outliers}
During my time at Oxford, the top 2 students in my Engineering cohort were both of Pakistani origin [A similar pattern is seen across other STEM subjects]. Surprised? You shouldn't be based on what we. In future articles, I will discuss some other factors which lead to a disproportionate number of top Asian students.
Why does this happen?
Quite simple, most parents have never heard of summer learning loss. They don’t know that their children experience a “summer slide” if their brains are not stimulated over the summer months. They don’t know that teachers spend the first weeks of school re-teaching material from the previous school year!
"Children struggle in September as they have forgotten prior learning. They then struggle to catch up because of the demands of SATS. To overcome that, attending Tuition during summer stands them in good stead from the off and gives them a greater advantage over other children".
Mr Shaikh, experienced primary school teacher and 11+ specialist.
What can you do about it?
Continue learning throughout the summer. It doesn't have to be super intense but as long as you have a good base prepared for when you go back then you should be fine.

What can this guide not tell you about one child?
Results and inspection judgements describe a school at one moment, and both move. Neither tells you how one particular child will do there, and a school that suits one family may not suit the next. Check the current position on Ofsted and compare school performance, then visit.
One caveat parents are rarely told:
“Other types of school, like academies and private schools, do not have to follow the national curriculum.” — gov.uk, The national curriculum
Where can you check this at source?
School performance, inspection judgements and admissions rules are published by the DfE and Ofsted. This is the record:
- Compare school performance (gov.uk) — results, progress scores and cohort data by school
- Ofsted reports — the current inspection judgement for any school
