A teacher stands at the front of a Year 4 classroom, with three fractions questions still on the board, and has about 4 seconds to decide whether the class is ready to move on or needs another 5 minutes on the same idea. That decision, repeated dozens of times a day, is what formative assessment is really about: checking understanding while there is still time to do something about it. In UK primary schools, where the National Curriculum expects steady progress across every subject and key stage, in-the-moment checking matters as much as any end-of-term test.
This guide covers what formative assessment is, how it differs from summative assessment, and the evidence base behind it. It sets out the core Assessment for Learning strategies that work in primary classrooms, including no-hands-up, mini-whiteboards, exit tickets, traffic lights, hinge questions, ABCD cards, and peer assessment, with worked examples for English, maths, and science lessons. It also covers how to plan the assessment into a lesson without it taking over, the pitfalls that catch teachers out, and downloadable resources to support both classroom practice and professional development conversations.
LearningMole, the UK educational platform founded by former primary school teacher Michelle Connolly, builds these techniques into maths, English and science resources aligned with the National Curriculum. This guide draws on that classroom experience alongside the wider research base, starting with Paul Black and Dylan Wiliam’s foundational work, to give teachers and teaching assistants something they can use in Monday’s lesson, not just read about.

Formative assessment is the ongoing checking of pupil understanding during learning, used to adjust teaching in real time. Summative assessment measures what has been learned after the fact, through end-of-unit tests, SATs, or termly assessments. The distinction is not about the tool used; a quiz can be formative or summative depending on what happens with the result. It is about purpose and timing.
If a Year 2 teacher uses mini-whiteboards to check who can partition a two-digit number, then reteaches the concept to a small group before the lesson ends, that is formative assessment. If the same teacher marks an end-of-topic test and records the score in a tracker, that is summative. Both have a place. The problem in many primary classrooms is not too much summative assessment, but too little assessment happening between the big tests.
| Feature | Formative Assessment | Summative Assessment |
|---|---|---|
| Purpose | Adjusts teaching and learning while it is happening | Measures and records what has been learned |
| Timing | During a lesson, topic or unit | At the end of a lesson, topic, term or key stage |
| Who acts on it | Teacher and pupils, immediately | School leaders, parents, next teacher |
| Typical examples | Mini-whiteboards, exit tickets, hinge questions, peer feedback | SATs, end-of-unit tests, termly assessments |
| Stakes for pupils | Low stakes, no grade attached | Higher stakes, often graded or scored |
| Feedback speed | Immediate or within the lesson | Days or weeks later |
Both forms sit within a balanced assessment system. Formative assessment keeps learning on track week by week; summative assessment shows whether that ongoing work has added up to secure progress over a term or key stage. Neither replaces the other.
Formative assessment matters because it catches misconceptions while they are still cheap to fix. A child who has quietly misunderstood place value in September will still be struggling in July if nobody checks in between. Waiting for the next test to find out is far too slow for a five-year-old learning to read or a ten-year-old learning long division.
It also changes who gets seen. Traditional hands-up questioning tends to surface the same confident five or six children in a class of thirty. Structured formative assessment, where every pupil responds on a whiteboard or every pupil has a coloured card raised, gives teachers a genuine picture of the whole room rather than a sample of volunteers. That matters for differentiation, for pupils with SEND, and for children who understand the material but are simply reluctant to speak in front of the class.
“The best lesson I ever taught looked like a mess from the back of the room: whiteboards up, children moving between groups, me crouched next to a table rather than standing at the front. But I knew exactly where every child was, because I had checked, not guessed. That is the whole point of the assessment; it replaces guessing with knowing,” says Michelle Connolly, Founder of LearningMole and former teacher with over 15 years of classroom experience.
Ofsted’s current inspection framework asks whether assessment is used to check understanding and inform teaching, rather than simply to generate data for tracking spreadsheets. Formative assessment, done well, is exactly what that looks like in practice: quick, frequent, and acted on immediately.
The strategies below are not new. Most have been used in English primary schools since the Assessment for Learning movement gained momentum in the early 2000s, following Black and Wiliam’s research. What makes them effective is consistency: used occasionally, they are a novelty. Used as part of the normal lesson routine, they become genuinely useful data.
Rather than taking answers from volunteers, the teacher chooses who answers, often using lolly sticks with names, a random name generator, or simply going around the room. Every pupil has to be ready to answer at any point, which keeps attention on the task rather than on who else might get picked. It works best paired with a brief thinking time before any name is called, so pupils are not caught out unfairly.
Every pupil writes an answer and holds it up on the count of three. The teacher scans the room in seconds and sees the whole class’s understanding at once, rather than one pupil’s. This works particularly well for maths calculations, spelling patterns, and quick recall questions in science. The main pitfall is pupils copying a neighbour’s answer; positioning and a clear “boards up together” routine reduce this.
A short question or task is completed on a slip of paper as pupils leave the lesson or move to the next activity. Exit tickets work best when they target one specific thing the lesson was meant to teach, rather than a general “how did you find today’s lesson” question. Sorting the tickets into three piles, secure, developing, and not yet, takes a couple of minutes and directly informs the next day’s starter or grouping.
Pupils show a red, amber, or green card, a cup, or a coloured peg to indicate how confident they feel about a concept. This is a self-assessment tool, so it needs to be taught explicitly; young children, in particular, tend to show green regardless of their actual understanding until they have practised being honest with it. It is most useful as a quick temperature check mid-lesson, not as the sole evidence of understanding.
A hinge question is a single multiple-choice question placed at a genuine decision point in the lesson, where each wrong answer reveals a specific, predictable misconception. The whole class answers within a set time (often under a minute), and the teacher decides on the spot whether to move on or address the misconception before continuing. Writing a good hinge question takes more planning than the other strategies here, because the wrong answers have to be diagnostic, not just incorrect.
Each pupil holds four cards labelled A, B, C and D and raises the one matching their chosen answer to a multiple-choice question. This gives the speed of mini-whiteboards with the diagnostic precision of a hinge question, since the teacher can see immediately which specific misconception is most common in the room, not just who is right or wrong.
Pupils check a partner’s work against a small number of clear success criteria, shared in pupil-friendly language before the task begins. This only works when the criteria are specific (for example, “has the writer used a fronted adverbial in at least two sentences?”) rather than vague (“is this good writing?”). Peer assessment also serves as a formative check for the assessor, since explaining what makes work successful deepens their understanding of the criteria.
| Strategy | What It Checks | Time Needed | Best Used For |
|---|---|---|---|
| No hands up | Individual recall and reasoning, whole class | Ongoing, no extra time | Any subject, any age group |
| Mini-whiteboards | Whole-class understanding in one glance | 2 to 3 minutes per check | Maths calculations, spelling, and quick recall |
| Exit tickets | Understanding of the lesson’s specific objective | 5 minutes plus sorting time | End of lesson, informing next day’s planning |
| Traffic lights | Pupil-perceived confidence | 1 minute | Quick mid-lesson temperature check |
| Hinge questions | Specific, predictable misconceptions | 1 minute plus planning time | Key decision points in a lesson |
| ABCD cards | Which misconception is most common | 1 to 2 minutes | Multiple-choice diagnostic checks |
| Peer assessment | Application of shared success criteria | 10 to 15 minutes | Extended writing, project work, KS2 |
Two downloadable resources accompany this guide: a strategy bank summarising each of the seven techniques above with ready-to-use prompts for English, maths and science, and a lesson observation template focused specifically on Assessment for Learning, designed for peer observation, mentoring conversations, or subject leader monitoring visits.
During a Year 3 lesson on inverted commas, the teacher sets a hinge question: which of the four short sentences has correctly punctuated direct speech? Three answer options each reflect a specific error, such as missing capital letters inside the speech marks or punctuation placed outside them. Within a minute, the ABCD cards show that 18 of 28 pupils have chosen the option missing the capital letter. Rather than moving on to independent writing as planned, the teacher spends five minutes re-modelling that one specific rule before pupils write their own dialogue.
In a Year 5 lesson on equivalent fractions, pupils use mini-whiteboards to show a fraction equivalent to one half at three points across the lesson: at the start, after the main teaching input, and after guided practice. The teacher tracks, informally, which pupils are still relying on the same equivalent fraction each time rather than generating new ones, a sign that understanding has not moved from recall to application. Those pupils are pulled into a small group for the final ten minutes while the rest of the class begins independent work.
Before a Year 4 lesson on states of matter, pupils complete a quick exit ticket from the previous lesson: name one example each of a solid, a liquid and a gas, and explain what happens when ice melts. The teacher sorts the tickets into three piles before planning the next lesson. Pupils who could name examples but not explain the change of state get a short, targeted explanation using visual diagrams at the start of the lesson, while the rest move straight into the practical investigation.
Formative assessment works best when it is planned at the same time as the lesson itself, not bolted on afterwards. Before teaching, identify one clear decision point where the lesson could genuinely go two different ways: continue as planned, or address a misconception first. Build a specific check into that moment, whether that is a hinge question, a mini-whiteboard task, or an exit ticket at the end.
It also helps to decide in advance what will happen with each possible result. If most of the class shows understanding, the plan is to move on. If a clear minority struggles, the plan might be a same-lesson small-group intervention. If the whole class is unsure, the plan should be to reteach the point differently, not simply repeat the original explanation more slowly.
Formative assessment goes wrong in a small number of predictable ways, most of which stem from treating it as an extra task rather than a normal part of teaching.
Assessing without adjusting. Collecting information about pupil understanding, then continuing exactly as planned, defeats the purpose. If a hinge question shows the class does not understand, the plan has to change.
Turning it into marketing. Recording a written comment on every exit ticket or whiteboard response every lesson is unsustainable and unnecessary. Most assessments should inform an immediate verbal or teaching response, not generate paperwork.
Public strategies that expose struggling pupils. Traffic lights or ABCD cards used carelessly can single out pupils who are already anxious about maths or reading. Build in genuine anonymity where it matters, or use strategies that do not require a public display of confidence.
Overusing one technique until it stops working. Mini-whiteboards used in every single lesson can become routine to the point that pupils stop engaging thoughtfully with them. Rotating strategies keeps pupils genuinely thinking rather than going through the motions.
Confusing confidence with understanding. Self-assessment tools like traffic lights measure how pupils feel, not what they know. They work best alongside a strategy that checks actual understanding, not instead of one.
Assessment for Learning as a distinct movement in English education traces back to Paul Black and Dylan Wiliam’s 1998 review, published as “Inside the Black Box: Raising Standards Through Classroom Assessment” in Phi Delta Kappan. Drawing on an extensive review of existing research, they concluded that classroom formative assessment, properly implemented, produced learning gains larger than most other educational interventions studied at the time, with reported effect sizes on standardised test outcomes in the range of 0.4 to 0.7.
That finding shaped assessment policy across England through the 2000s and remains one of the most cited pieces of assessment research in UK education. Later research has nuanced the picture; subsequent reviews have found the effect varies by subject, by how the assessment is implemented, and by whether feedback is used to adjust teaching or simply given to pupils without follow-up action. The consistent thread across the research since 1998 is that the assessment only works when the information gathered actually changes what happens next in the classroom.
For UK primary teachers, the practical implication has stayed remarkably stable for over two decades: frequent, low-stakes checks that feed directly back into teaching decisions outperform infrequent, high-stakes testing as a way of raising standards day to day.

Formative assessment checks understanding during learning so teaching can be adjusted immediately, while summative assessment measures what has been learned after the fact, typically through tests. Formative assessment is low stakes and acted on straight away; summative assessment is usually recorded and reported. A balanced classroom uses both.
Formative assessment strategies suit every primary age group when adapted appropriately. Reception and Key Stage 1 pupils respond well to simple visual tools such as traffic lights or thumbs signals, while Key Stage 2 pupils can manage more complex peer assessment and hinge questions with clear success criteria. The principle of checking understanding before moving on applies from age four upwards.
The National Curriculum sets out what pupils should learn in each subject and key stage, but it does not prescribe how teachers should check that learning is taking place. Formative assessment is the practical mechanism schools use to monitor progress against curriculum objectives between formal assessment points, helping teachers identify gaps before they affect a pupil’s progress across a key stage.
Beyond simple tools like mini-whiteboards and coloured cards, teachers can use structured hinge questions, exit ticket templates, and lesson observation frameworks focused on Assessment for Learning. LearningMole’s strategy bank and lesson observation template, linked above, are designed specifically to support formative assessment practice across English, maths and science.
Parents can use a simplified version of the same principle: checking understanding little and often rather than only at test time. Asking a child to explain a concept in their own words, or to teach it back, works as an informal formative check. It reveals genuine understanding far more reliably than asking whether homework is finished.
The most common misconception is that formative assessment means constant marking or written feedback on every piece of work. In practice, most effective assessment is verbal, immediate, and unrecorded; its value lies in changing what the teacher does in the next few minutes, not in generating evidence for a folder.
The strategies with the lowest workload impact, no hands up, mini-whiteboards, and traffic lights, require no recording at all; the assessment happens and informs teaching in the same moment. Workload increases when schools ask teachers to log every formative check, often indicating confusion between the assessment and evidence-gathering for accountability purposes.
Formative assessment identifies, in real time, which pupils need more support, which are secure, and which are ready to be stretched further. That immediate picture is what makes genuine differentiation possible, rather than differentiation planned in advance based on assumptions about who will struggle with a particular topic.
Formative assessment is not a separate initiative to add on top of an already full teaching day. Done well, it is simply good teaching, made visible: checking whether pupils understand before moving on, rather than hoping they do. The strategies covered here, no hands up, mini-whiteboards, exit tickets, traffic lights, hinge questions, ABCD cards and peer assessment, all achieve the same basic goal through different means, and most primary teachers already use some version of at least two or three of them.
What tends to separate strong formative assessment practice from weaker versions is not the choice of strategy but the discipline of acting on what it reveals. A hinge question that shows widespread misunderstanding only has value if the lesson plan changes in response. An exit ticket sorted into three piles only helps pupils if that sorting shapes tomorrow’s grouping or starter activity. The evidence from Black and Wiliam onwards points in the same direction across nearly three decades: formative assessment raises standards when it changes teaching, not when it simply produces information.
For teachers building this into everyday practice, the strategy bank and lesson observation template above offer a practical starting point, whether for personal use, a staff meeting, or a subject leader’s monitoring cycle. Choosing one or two strategies to embed consistently, rather than trying all seven at once, tends to produce more lasting change in classroom practice than a scattergun approach ever does.
