Your child just finished Year 6 SATs. Here's the summer mistake nearly every parent makes.

SATs week is the end of something. For most Year 6 children, it's the end of formal primary education. The next six weeks of summer feel like a reward. The problem is what happens in those six weeks — and what happens in October.

The summer your child just earned

First, the obvious thing. Your child has just finished six years of primary school, plus the most pressured testing week of their school career so far. They deserve a proper summer. Long, slow, screen-time-tolerant, late-bedtime, ice-cream-for-breakfast summer. Nothing in this post is going to argue against that.

But there's a specific trap waiting in September that nobody warns you about, and the children who get caught by it spend the autumn term quietly struggling while everyone assumes they're just "settling into Year 7". Knowing about it now means you can avoid it with about 20 minutes of effort per day — without ruining the holiday.

What "doing nothing" actually costs

The phenomenon is called summer learning loss, and the data on it is uncomfortable. Research by the Education Endowment Foundation and US studies tracking the long Atlantic summer break consistently find that children lose between 1 and 2 months of academic progress over an unbroken summer break. The loss is steeper in maths than in reading. The loss is steepest in children from less academic households, but it affects every demographic.

Two months of lost progress, on top of the natural disorientation of moving to secondary school, is a hard combination. By October half-term, around a third of Year 7 students are below where they were in May of Year 6. By December, teachers are running catch-up groups for them.

The summer slump is real, it is measurable, and it is almost entirely preventable with twenty minutes of low-effort maintenance a day.

The simple 20-minute rule

The fix is not tutoring. The fix is not flashcards. It is twenty minutes a day, four or five days a week, of low-stakes academic activity that the child does without resentment. Here is the actual menu that works for most families:

• Reading for pleasure (20 minutes). Any book the child chooses. Graphic novels count. Football autobiographies count. Re-reads count. This single activity does more for Year 7 readiness than any other intervention.
• One page of arithmetic practice (10 minutes). Times tables, mental maths, simple problems. CGP, White Rose, Schofield & Sims — pick a workbook and do a page a day. The aim is fluency maintenance, not new learning.
• One short writing task per week. A postcard from a day out, a review of a film they watched, a letter to a grandparent. Half a side of A4. The aim is to keep the writing muscle alive.

That's it. Thirty minutes a day, four days a week. About two hours per week of total "work". Done consistently across six weeks, this is enough to preserve almost all the academic progress your child made in Years 5 and 6.

The reading habit is the single biggest lever

If you do nothing else, focus on reading volume. The data on this is unambiguous: children entering Year 7 who read for pleasure for 20+ minutes a day across the summer score, on average, half a grade higher in their first end-of-year English assessment than children who don't. The effect persists into Year 8.

The trick is choice. Children do not read books their parents pick for them. They read books their friends recommend, books they discover at the library, books with covers they like. Take them to the library. Let them choose six books. Let them abandon three. Reading is a habit, and habits are killed by force.

The maths trap nobody warns you about

Maths is the subject most vulnerable to summer slide because it is sequential. A child who has forgotten how to find a fraction of a number cannot do percentages, and a child who can't do percentages cannot do most Year 7 maths. The first half-term of Year 7 maths assumes the child remembers everything from Year 6.

The fix is not to push ahead into Year 7 content. It is to keep the Year 6 content warm. Pick one of these and do it 10 minutes a day:

• Times Tables Rock Stars or similar. Free, gamified, ruthlessly effective for the under-12s. Most children will do this voluntarily for 10 minutes.
• A workbook page. The CGP Year 6 Maths Workbook or the White Rose home-learning workbook. One page is enough.
• Mental maths apps. Doodle Maths, Komodo, Maths-Whizz. £5-10/month, useful for slightly-older Year 6s who like screens.

When NOT to bring in a tutor

Most children do not need a summer tutor between Year 6 and Year 7. They need a maintenance plan, not a new curriculum. Hiring a tutor for the summer often creates resentment, kills off goodwill towards the new school, and produces marginal academic gains. Use the summer for sleep, family, books and consolidation.

There are three exceptions where a summer tutor genuinely helps:

1. Your child finished Year 6 with a clear, specific gap — for example, they never quite got long division, or they consistently lost marks on fraction questions. A focused 6-8 sessions across summer can close that specific gap before Year 7 builds on it.
2. Your child is moving to a selective or independent secondary school and the school has set a summer reading list or holiday assignment. A tutor can keep things calm and on track.
3. Your child sat the 11+ this year — and didn't get the result you hoped. A summer focused on confidence-rebuilding and gap-filling matters more than the 11+ result itself, especially before Year 7.

What your child should know by September

Here is the honest checklist. By the start of Year 7, your child should be able to:

• Recite their times tables up to 12 × 12 in under four minutes.
• Add and subtract fractions with different denominators.
• Find a percentage of a number (e.g. 15% of 60) without a calculator.
• Read aloud confidently from a chapter book.
• Write half a page of legible, paragraphed prose with capital letters and full stops.

If they can do those five things, they are ready. If they can't, you have six weeks to fix it, and the fix is gentle daily practice — not a six-week academic boot camp.

The honest end-note

Let them have the summer. Let them stay up late, get bored, play in the garden, fall out with their friends, watch too much YouTube. That's what summer is for. Then for 20-30 minutes a day, keep their brain alive. By September, you'll have a child who is rested, healthy and academically ready — and that combination is rare enough that secondary teachers will notice it within the first week.
