Formative vs Summative Assessment: Differences & Examples

“Formative” and “summative” are two of the most-used words in teaching — and two of the most muddled. The distinction is actually simple, and getting it right changes how you design and run every check for understanding. Here’s the difference in plain English.

The one-line difference

Formative assessment is assessment for learning. Summative assessment is assessment of learning.

Formative happens during learning to guide what comes next. Summative happens after a chunk of learning to measure what was achieved. Same activity, different purpose — and the purpose is what matters.

Formative assessment

The goal is feedback, not a grade. You’re taking the temperature of the room so you can adjust on the spot. It’s low-stakes by design — learners should feel safe being wrong, because being wrong is the point.

• Examples: a quick live quiz, a discussion board, a drag-and-drop check, exit tickets.
• Feedback: immediate, often shown instantly.
• Stakes: low — usually ungraded.
• Frequency: often, sometimes several times a lesson.

Summative assessment

The goal is to measure and record achievement against a standard — the end-of-unit test, the final project, the certification exam. Because it counts, you generally hold results back until everyone has finished and you’ve reviewed them.

• Examples: end-of-module exam, graded essay, final assessment.
• Feedback: after marking; results released deliberately.
• Stakes: higher — contributes to a grade or pass/fail.
• Frequency: occasional, at natural end points.

A simple rule for choosing

Ask one question: “Am I using this to change my teaching, or to record a result?” If it’s to change your teaching, run it formatively — show scores, discuss the tricky ones, move on. If it’s to record a result, run it summatively — hide scores until release, and keep the conditions consistent.

You need both

Formative and summative aren’t rivals. Frequent formative checks mean nobody is surprised by the summative one — you’ve been steering the whole way, so the final measure simply confirms what the journey already showed.

Side by side

Where the terms come from

The distinction was first drawn by the philosopher Michael Scriven in 1967, writing about how to evaluate educational programmes; Benjamin Bloom and colleagues then applied it to the assessment of learners. The idea gained its modern weight in 1998, when Paul Black and Dylan Wiliam reviewed the research in Inside the Black Box and argued that strengthening formative assessment was among the most effective ways to raise achievement. “Assessment for learning” — the phrase most UK teachers know — grew out of that work.

Formative assessment examples

• Hinge questions — one carefully chosen multiple-choice question mid-lesson, where each wrong answer reveals a specific misconception. The lesson “hinges” on the result.
• Low-stakes quizzes — a few questions at the start of a lesson on previous material.
• Exit tickets — one or two questions answered on the way out: what did you learn, what are you unsure about?
• Think–pair–share and group discussion — listening to how learners explain an idea to each other.
• Drafts with comments — feedback on work that can still be improved.
• Self and peer assessment — learners judging work against the criteria, which teaches the criteria.

Summative assessment examples

• End-of-unit or end-of-term tests
• GCSE, A level and other public examinations
• Graded coursework, essays and dissertations
• Final projects, portfolios and presentations
• Practical or competency sign-offs in vocational and professional training

Can one assessment be both?

Yes — because the label belongs to the use, not the task. A mock exam is summative in form and formative in purpose: sat under exam conditions, then used to decide what to revise. An end-of-unit test becomes formative the moment you go through it with the class and reteach the weakest question. And a graded essay returned with comments nobody is asked to act on is summative, however detailed the comments.

The third type: diagnostic assessment

Diagnostic assessment happens before teaching, to find out what learners already know and where the misconceptions are. A short pre-quiz at the start of a topic is the usual form. It is really formative assessment used early — its job is to shape what you teach, and it should never be graded.

Common mistakes

• Grading the formative work. Once there is a mark on it, learners look at the mark and stop reading the feedback.
• Collecting information and not using it. A check that doesn’t change what you do next was just a test.
• Feedback with nothing to do. “Good effort” and “needs more detail” give a learner no next step. Say what to change, and give time to change it.
• Only ever assessing at the end. By then it’s a verdict. Learners needed to know in week three, not week twelve.
• Loose conditions on summative work. If it counts, it has to be the same test, the same time and the same help for everyone.
