How to improve reading fluency in KS2

Reading fluency is the bridge between decoding a word and understanding it. A child who has to work to recognise each word has no attention left over for meaning, so the words arrive flat and the sense never lands. In KS2 this becomes the problem that sits underneath every other reading problem, because the texts get longer, the curriculum assumes children can read to learn, and the children who never built fluency start to fall behind across every subject. This guide sets out what actually improves fluency in KS2, the methodology we use, and the evidence behind each part.

A word on where I am writing from. I led primary schools for seven years before becoming a headteacher of an infant school, so I have seen the KS2 end of this problem at close range, and I now lead the years where the foundation for it is built. The approaches below come from both ends of that gap.

What is reading fluency, and why does it stall in KS2?

Fluency has three strands. Accuracy is reading the words correctly. Automaticity is reading them instantly, without effort. Prosody is reading them with expression, so they sound like meaning rather than a list. A child can be accurate and still not fluent, because if every word costs effort, there is nothing left for comprehension.

The DfE's Reading Framework describes fluency as the bridge from word reading to comprehension, and that is the right image. In KS1 the focus is correctly on decoding. The difficulty is that decoding success can mask a fluency problem, and a child can pass the phonics screening check while still reading word by word. I have written separately about that automaticity gap behind good phonics results. By KS2 the gap is harder to hide and harder to close, because the demands have grown.

The scale is not small. FFT Education Datalab's 2024 analysis, the largest study of reading fluency yet conducted in England, found the lowest-attaining quarter of Year 6 readers reading at a level most children reach years earlier. That gap is often invisible, because the children read accurately enough to seem fine.

The strategies that improve KS2 fluency

These are in rough order of impact. Almost none of them costs money, which matters when school budgets are as tight as they are. What they cost is time and intention.

1. Repeated reading, built into something worth repeating

Repeated reading is the most evidenced fluency strategy there is, but the version most often described, read the same passage again and again, sounds like drudgery and quickly becomes it. The skill is in giving children a reason to return to a text, so the repetition is rehearsal rather than rote.

We do this in two ways. The first is poetry. We run a poem of the week, where the children meet one poem on Monday and revisit it in a different form each day: teacher modelling, echo reading, choral reading, partner reading, and a performance on Friday. The same text becomes easier across the week without becoming boring, because the children are practising towards an audience. This routine is built directly on Timothy Rasinski's Fluency Development Lesson (Rasinski, Padak, Linek and Sturtevant, 1994), and I have written up the full week-long routine, with a free planner.

The second is our fluency book lessons. The children work through a story, a chapter every two days, and each chapter carries the same structure: modelled reading from the teacher, my-turn-your-turn, choral reading with a partner, choral reading as a whole class, and annotated passages where the text is marked up for phrasing and expression. It is repeated reading, but it never feels like reading the same thing twice, because each pass has a different job.

2. Reading aloud to children, every day

Before a child can read fluently, they need to hear what fluent reading sounds like. An adult reading aloud well, with expression, pausing at the full stops, lifting the voice for a question, is the model children copy. This is the cheapest intervention on this list and among the most powerful, and it is the first thing squeezed out when timetables tighten. Protect it.

3. Choosing texts at the right level

A child practising fluency on a text that is too hard reverts to word-by-word decoding, because all their effort goes into getting the words out. Fluency practice needs texts the child can already read comfortably, so the work is on smoothness, not survival. I have made this argument at length in why making the text harder makes fluency worse. Save the richer, harder texts for reading aloud to them, where you carry the load.

4. Performance and prosody

Prosody is the strand schools teach least and the one most tied to comprehension, because you cannot read a sentence with the right expression unless you have understood it. Performance gives prosody a purpose. A poem performed on Friday, a passage read aloud in character, a line delivered crossly then kindly to feel the difference. This is also where children who found reading a chore often begin to enjoy it, which matters more than any score.

5. Measuring fluency, so you can target it

You cannot target what you have not measured, and most schools measure phonics and comprehension but never fluency, the thing between them. Listening to a child read a short unseen passage and noting words correct per minute alongside a judgement of expression takes two or three minutes, and it tells you precisely who needs help and whether the help is working. When we measured this with our own Year 2 children, thirty-two of them gained an average of twelve words per minute in four months, with accuracy climbing to 98.5 per cent, and the children we had worried about most made the biggest gains. We only knew that because we measured it.

What I found when I went looking for help

When we set out to teach fluency properly, the striking thing was how little there was to lean on. There is no established fluency programme in the way there is for phonics. There are some early efforts, and a great deal scattered across blog posts and research summaries, but very little built into a usable classroom routine. The assessment tools that do exist are often good, and priced beyond what a small school can easily justify.

That absence is the reason we started building what we are building. Not because there was a programme that failed us, but because there was no programme at all, and the gap was too important to leave.

Where to start if you lead reading in your school

Do not try to do all of this at once. Start with the two that cost least and give most: read aloud to your children every day, and build repeated reading into your lessons using texts the children can already manage comfortably. Poetry is the easiest way in, because a poem is short enough to learn in a week and made to be read aloud. Then, before you buy any programme, find out where your children actually are by listening to them read and noting fluency directly. The targeting comes from the data, and the data is quick to gather.

A child reading word by word is not a failing reader. They are a reader part-way through a build, and fluency responds quickly once you teach it on purpose.
