Common SATs Reading Mistakes (and How to Fix Them)

The errors children make most often in the KS2 reading paper — and exactly what you can do at the kitchen table tonight to fix each one.

Most lost reading marks come from a few fixable habits

When children lose marks in the reading paper, the cause is usually one of a few fixable habits. They followed the story perfectly well; they just answered the question the wrong way — scanning an inference question for a word that was never printed, or writing one short line for a question quietly worth three marks. Most of these turn around in short sessions at home.

Below are the five mistakes children make most, each with a concrete example, the fix, and one thing you can try tonight. If you want the marking system behind them, our guide to how SATs papers are marked covers exactly that; this page is about the errors themselves and what you do about them.

The five most common reading mistakes

Confusing retrieval with inference

What goes wrong: Your child treats every question the same way — scanning for the answer word-for-word. That works for a retrieval question, but on an inference question there is no sentence to copy, so they write "it doesn't say" and leave the marks behind.

Why it happens: The reading paper asks two very different kinds of question. A retrieval question (content domain 2b) wants information that is stated in the text — you can point to it. An inference question (content domain 2d) wants something you work out from clues, where the exact answer is never written down. Children who do not know which kind they are facing answer the wrong way.

A short passage

“The morning the lighthouse went dark, Mara pulled on two jumpers before she even opened the door. Outside, the gulls had vanished and the sea had turned the colour of slate. She checked the rope on the little boat twice, then twice again.”

2b · retrieval

How many jumpers did Mara put on?

Answer: Two.

Stated word-for-word — "pulled on two jumpers". You can point to it.

2d · inference

How can you tell rough weather was coming?

Answer: The gulls had vanished, the sea had turned the colour of slate, and Mara checked the rope twice (and again) — clues that a storm was on the way.

Worked out from clues. The word "storm" never appears, so there is nothing to copy.

Wrong

Question (inference): "How can you tell rough weather was coming?" Child writes: "It doesn't say." (scanned for the word "storm", couldn't find it, gave up)

Right

"You can tell because the gulls had vanished, the sea had turned the colour of slate, and Mara checked the rope twice." (joins up the clues — the word "storm" is never used)

The fix: Teach your child to spot the question type first. "Find / what / who / when" usually means retrieval — go and point to it. "How do you know / why / what does this suggest" means inference — gather two or three clues and join them up. See more on our inference practice and retrieval practice.

Try this at home tonight: Read a few lines of any book together, then ask one question you can point to ("What colour was the door?") and one you have to work out ("How do you think she was feeling?"). Name each one out loud as retrieval or inference.

Answering without evidence from the text

What goes wrong: Your child gives an opinion or a guess instead of pointing back to the words on the page. The answer might even be sensible, but with nothing from the text behind it the marker cannot award the mark.

Why it happens: The marker only credits answers that come from the passage. Many questions explicitly ask children to "use evidence from the text", and the mark schemes reward answers that quote or clearly point to it; a sensible-sounding guess on its own earns nothing.

Wrong

Question: "How do you know Mara was worried about the weather?" Child writes: "Because she was scared of the storm." (an invented feeling — nothing from the text)

Right

"You can tell she was worried because she put on two jumpers and checked the rope on the boat twice, and then twice again — she was getting ready for rough weather." (refers straight back to the words on the page)

The fix: Build one habit: every answer either quotes the text or points to a specific detail in it. A quick rule of thumb at home — "show me the bit that proves it" — turns a guess into an evidenced answer. See more on our comprehension tips.

Try this at home tonight: When your child answers a question about a book, follow up every time with "which words tell you that?" until pointing back to the text becomes automatic.

Under-answering multi-mark questions

What goes wrong: A question is worth 3 marks, but your child writes a single short line. One point can only ever earn one mark, so two of the three are gone before the marker has finished reading.

Why it happens: On the reading paper the number of marks is a strong signal of how much to write. A 3-mark "explain" question is looking for a developed, evidenced answer — usually several separate points, or one point properly explained and supported with evidence from the text. The mark scheme awards a mark for each valid, evidenced point, so a one-line answer caps itself at one mark.

Wrong

Question (3 marks): "Explain how the writer makes the opening feel tense. Use evidence from the text." Child writes: "Because the lighthouse went dark." (one point → 1 mark at most; 2 marks lost)

Right

Three developed, evidenced points: • The lighthouse "went dark", which signals at once that something is wrong. • "the gulls had vanished" hints at danger, because animals often sense it first. • Mara "checked the rope... twice, then twice again", showing she is anxious. (three points, each tied to the text → up to 3 marks)

Check the marks in brackets and treat them as a target: roughly one developed, evidenced point per mark.

The fix: Look at the marks before answering. For a 2- or 3-mark question, plan that many points and tie each one to the text. A good check: count your points and make sure there are at least as many as there are marks. See more on our comprehension tips.

Try this at home tonight: Take any 3-mark practice question and ask your child to give you three separate reasons, each with a bit of the text behind it — turn it into a quick "three things" game.

Guessing vocabulary instead of using the sentence

What goes wrong: Asked what a word means, your child guesses from how it looks or sounds, or skips it — rather than using the rest of the sentence, which usually gives the meaning away.

Why it happens: Vocabulary questions (content domain 2a) ask what a word means in this particular sentence, which can differ from its everyday dictionary meaning. The clues are almost always in the surrounding words, so reading the whole sentence is the method itself.

Wrong

Sentence: "The path wound through the trees and the children trudged home, soaked and silent." Question: What does "trudged" suggest about how the children were walking? Child writes: "ran" (guessed from the look of the word)

Right

Use the clues around it — "soaked and silent", heading "home" after a long walk — so "trudged" means walked slowly and heavily, as if tired and fed up. (meaning taken from the sentence, not from a guess)

The fix: Teach a three-step method: read the whole sentence, look for clues either side of the word, then read it again with your guess swapped in to check it still makes sense. See more on our comprehension tips.

Try this at home tonight: While reading together, cover one tricky word with your finger and ask your child to guess it from the rest of the sentence — then reveal it and see how close they were.

Running out of time (and over-copying)

What goes wrong: Your child reads every text slowly from start to finish, then starts the questions with too little time left. They also copy out long chunks of the passage for a question worth a single mark.

Why it happens: The KS2 reading test is one paper of an hour, and the booklet usually holds three texts of increasing difficulty. Reading everything in full before looking at a single question, and then over-writing on the easy marks, leaves no time for the harder questions at the end where the marks are hardest to find.

Wrong

Reads all three texts slowly twice, then races the questions with ten minutes left — and writes a full paragraph for a 1-mark "find and copy" answer.

Right

Skim each text once for the gist, read the question, then scan back to the exact part that answers it. Match the answer to the marks: 1 mark = a few words, not a paragraph.

The fix: Practise the order: skim, read the question, scan back for the evidence. Watch the mark in brackets so the length of the answer fits the marks on offer, leaving time for the longer questions. See more on our comprehension tips.

Try this at home tonight: Do one short timed passage together with a kitchen timer, and afterwards talk about where the time went rather than only about right and wrong answers.

Where this comes from

The reading SATs are set by the Standards and Testing Agency (opens in new tab), part of the Department for Education. The question types above — retrieval (2b), inference (2d) and vocabulary in context (2a) — are the STA’s own content-domain references, and the way answers are credited comes from the published mark schemes. None of it is data of ours.

You can read it first-hand: the Key stage 2 English reading test framework (opens in new tab) sets out the content domain, the published KS2 past papers and mark schemes (opens in new tab) show exactly how each answer is credited, and the national curriculum English programmes of study (opens in new tab) set out what children are expected to know by the end of Year 6.

Frequently Asked Questions

What's the difference between retrieval and inference?

Retrieval (content domain 2b) means finding information that is actually stated in the text — you can point to the words. Inference (content domain 2d) means working something out from clues when the answer is never written down directly, such as how a character is feeling or why something happened. The simplest test: if you can copy the answer straight from the page it is retrieval; if you have to join up clues, it is inference.

Why does my child lose marks on the reading paper?

Usually for a few avoidable reasons rather than not understanding the text: answering an inference question as though it were retrieval, giving an opinion without pointing back to the words, writing one short line for a question worth two or three marks, guessing a word instead of using the sentence around it, or running out of time. Each of these is a habit, and a few minutes of the right practice most nights tends to clear them well before the tests.

How do I help my child with inference?

Read a little together every day and ask "how do you know?" and "what makes you think that?" so your child gets used to backing up answers with clues from the text. Point out that inference questions never have the answer written down — they have to gather two or three details and join them up. Short, regular practice builds the habit, and you can try our inference practice set to make it concrete.
