How to use KS2 SATs past papers - a Year 6 parent's guide

Of all the ways to prepare a Year 6 child for the KS2 SATs, past papers are the single most useful - and the cheapest. They're the real thing: the actual papers sat by hundreds of thousands of children, written by the Standards & Testing Agency, with the official mark schemes that tell you exactly how each answer is credited. Nothing a tutor or a workbook can produce matches them for authenticity.

And yet most families get very little out of them. The usual pattern is to print a stack of papers, have the child work through one after another, mark them for a score, feel briefly pleased or worried about the number, and move on to the next. Six weeks of that, and the child is almost exactly as good as when they started - strong on what they were already strong on, shaky on the same things they were always shaky on.

This guide is about the difference between doing past papers and learning from them. It's written for parents, and it assumes no teaching background.

What the KS2 SATs actually are

Before the papers make sense, a quick map of what Year 6 children sit in May:

• English reading - one paper. A reading booklet with three texts, and a separate answer booklet. The texts get harder as you go, and time pressure is the real challenge.
• English grammar, punctuation and spelling (GPS) - two papers: Paper 1 is short grammar and punctuation questions; Paper 2 is a spelling test read aloud.
• Maths - three papers: Paper 1 is arithmetic (pure calculation, no words), and Papers 2 and 3 are reasoning (word problems and multi-step questions).

Each test is marked out of a raw total, then converted to a scaled score from 80 to 120. 100 is the "expected standard". 110+ is often described as "greater depth" or a high score. You'll see a raw-score-to-scaled-score conversion table published with each year's papers - ignore it for day-to-day practice; it changes slightly every year and chasing a precise scaled score at home adds stress without adding learning.

> Science is no longer a national test for most children - the KS2 Science SATs were discontinued as a universal test in 2009, so the older science papers are useful extra practice rather than exam rehearsal.

The trap: papers as performance, not feedback

Here's the pattern that doesn't work, in detail:

1. Monday: child does a reasoning paper, scores 55/110.
2. Tuesday: you mark it, note the score, maybe sigh a little.
3. Wednesday: child does the next paper, scores 57/110.
4. Thursday: mark that one too.
5. Repeat for a month.

The child gets through eight papers and the score barely moves, because the marks being lost are mostly the same marks every week - the same couple of fraction questions, the same "explain your answer" questions left blank, the same long-division slips. Nothing in the routine ever turns a lost mark into a learned skill. The mistakes just get more practised.

The fix isn't fewer papers or more papers. It's treating each paper as the start of a loop, not a one-off test.

The loop that actually works

1. Do the paper. (Timed or untimed - see below.)
2. Mark it with the official mark scheme, not a quick answer key. The mark scheme shows why a mark is given - which is where the learning is.
3. Write down the topic, not the question. A missed question on "find 3/5 of 40" becomes an entry on a list: "fractions of amounts". A blank "explain how you know" becomes "showing reasoning in words". You're building a short list of weak topics, not a list of question numbers.
4. Practise that topic before the next paper. Ten quick questions on fractions of amounts, spread over a few days, closes that gap far better than doing another whole paper.

A child who does three papers and works the loop properly will overtake a child who does eight and treats each as a performance. The first child's weak list is shrinking every week; the second child's isn't moving.

A sensible rhythm for the spring term of Year 6: about one paper a week, with a few short topic-practice sessions in between, ramping up to two a week only in the last fortnight - by which point most of the gaps should already be closing.

Why re-doing the same paper is mostly wasted

It's tempting to re-do a paper a week later "to check they've improved". Resist it. A few days after marking, children remember the answers, not the methods - so the second score is almost always higher while the actual skill is unchanged. To test whether a topic has genuinely improved, give questions on the same topic from a different year's paper. Different numbers, different wording - now they either have the skill or they don't.

Timed vs untimed

Start untimed. The first job is to learn the material and the question styles, and a stopwatch at that stage just manufactures panic. Once a topic is secure, switch to timed conditions to build exam stamina - especially for the reading paper, where running out of time is the single biggest cause of lost marks.

Paper-by-paper tips

• Reading: timing is everything. Teach your child to read the questions first, then go hunting in the text for the answers, rather than reading all three texts cover to cover first. Points-based questions (2- and 3-mark) need more than one idea - a one-word answer won't score full marks.
• Arithmetic (Maths Paper 1): this is about speed and accuracy. Short, frequent sessions (10-15 minutes a few times a week) beat one long slog. Formal written methods for long multiplication and division are worth drilling until they're automatic.
• Reasoning (Maths Papers 2 & 3): the marks are often in the working. Encourage your child to always show their method - many questions award a mark for the correct approach even when the final answer is wrong. "Explain" and "how do you know" questions must be answered in words.
• GPS: Paper 1 rewards knowing the terminology (subordinate clause, modal verb, fronted adverbial). Paper 2 is spelling - little and often, from the published word lists, works far better than cramming.

Teach your child to mark their own work

One of the highest-value habits you can build: sit with the mark scheme and have your child mark their own paper, out loud, explaining why each mark is or isn't awarded. It forces them to read the mark scheme's language - "accept any answer that…", "do not accept…" - which is exactly the thinking the test rewards. After a few papers, they'll start writing answers the way the mark scheme wants them written.

Keep it in proportion

The SATs are one week in May. They matter for secondary-school setting and they're a useful milestone, but they are not a verdict on your child. A calm household that does a little, consistently, will almost always get a better result than an anxious one cramming in April - and will protect your child's relationship with learning, which matters far more than a scaled score. Little and often, lots of encouragement, and a focus on closing specific gaps rather than chasing a number.

How to use this on ExamVault (free)

• Download every official paper, free: our KS2 SATs past papers page has the real Maths, English, GPS and (older) Science papers from 2015 onward, with mark schemes and worked solutions - free with a free account.
• Practise online with instant marking: the KS2 SATs practice papers mark themselves and show a full answer review, so you skip the marking and go straight to the loop above. There's a free taster per subject.
• Close the gaps automatically: KS2 adaptive practice turns the weak topics you spot in a past paper into a short daily set tailored to your child - so the "practise that topic" step happens on its own.

Start with one past paper this week. Mark it with the official scheme, write down the two or three topics that lost marks, and spend the next few days on just those. That one change - topics, not papers - is what moves the score.
