What is inference? How to teach it? Worked examples and activities for Years 3–6.
Inference is the ability to read between the lines — to understand what a text implies without stating directly. It is the comprehension skill most commonly tested in KS2 SATs, the one children find most challenging, and the one most likely to distinguish strong readers from weaker ones. This page explains what inference is, how to teach it and provides worked examples from popular KS2 books.
When a text says something, inference is understanding something else that follows logically from it. For example:
Text: "Tom's hands shook as he reached for the door handle. He hadn't slept in two days."
Retrieval question: How long had Tom not slept? (Answer: two days — stated directly)
Inference question: How is Tom feeling? How do you know? (Answer: frightened/exhausted — implied by shaking hands and lack of sleep)
The difference is that retrieval finds information the text gives you; inference works out information the text implies. KS2 children need to do both, but inference is harder and worth more marks in SATs.
Inference requires children to do several things simultaneously: understand the literal meaning of the text, connect it to prior knowledge, identify what is being implied, and then explain their reasoning with reference to the text. For children who are still building reading fluency, this cognitive demand can be overwhelming.
The most common inference errors are: taking text at face value without considering implications, confusing 'what the text says' with 'what the text means', and failing to use textual evidence to support inferences (substituting personal opinion instead).
Passage: Mr Wormwood never took any notice of either of his children at the best of times, but he was particularly uninterested in Matilda.
Simple inference: How does Mr Wormwood feel about his children?
He doesn't care much about either of them, but cares even less about Matilda. Evidence: 'never took any notice' and 'particularly uninterested'.
Complex inference: What does this tell us about what kind of father Mr Wormwood is?
He is neglectful and self-centred — he ignores his children rather than engaging with them. The phrase 'at the best of times' implies that when things are difficult, he is even less attentive. This suggests his children's wellbeing is not a priority for him.
Passage: Joey was given a new name by each person who owned him, yet he always knew who he was.
Simple inference: What does this suggest about Joey's sense of identity?
Joey's identity is not determined by what others call him — it comes from within. Evidence: 'he always knew who he was'.
Complex inference: How does this detail reflect one of the novel's key themes?
It connects to the theme of loyalty and constancy in a world of constant change. Joey remains himself despite being passed from owner to owner, just as Albert's love for him remains constant despite the chaos of war.
Passage: Charlie Bucket was not complaining. He felt very lucky to be with them at all.
Simple inference: How does Charlie feel about his family's situation?
He feels grateful rather than resentful. Evidence: 'felt very lucky'.
Complex inference: What does this tell us about Charlie compared to the other golden ticket winners?
While the other children demand more, Charlie appreciates what he has. This positions him as genuinely virtuous — his goodness is not performed but comes naturally. This makes his eventual reward feel earned.
SATs inference questions typically use the prompts:

Inference work can begin in Reception and Year 1 through picture books and read-aloud conversations. The vocabulary and explicit teaching develops through KS1 and KS2. By Year 4, most children should be engaging with inference regularly in both reading and writing.
These terms are often used interchangeably in KS2, but technically: inference involves using background knowledge to fill in gaps the text leaves; deduction involves using evidence within the text to reach a logical conclusion. In practice, most KS2 comprehension questions that require 'reading between the lines' involve both.
Inference questions in KS2 SATs require children to explain how or why, provide evidence for their answer, and demonstrate understanding of implied meaning. They are typically worth more marks than retrieval questions and require extended written responses.
