7 Formative Assessment Strategies for Better Teaching

What Formative Assessment Actually Is

Formative assessment is the moment-to-moment work of figuring out what students know so you can adjust your teaching. It is different from summative assessment, which measures learning after the fact through tests and grades. The point of formative assessment is not to score students. It is to gather evidence you can act on in the next minute, the next activity, or the next lesson.

Paul Black and Dylan Wiliam's 1998 review of 250 studies, Inside the Black Box, found that consistent use of formative assessment produced learning gains with effect sizes between 0.4 and 0.7. That is among the largest effects ever reported for any classroom intervention. Wiliam later organized the field around five key strategies, which the seven techniques below all draw from.

Strategy 1: Make Learning Goals Crystal Clear

Students cannot self-correct toward a target they cannot see. Before any lesson, share what success looks like in plain language. A learning goal is not the activity ("we will read chapter 5") — it is the understanding ("you will be able to explain how a thesis statement frames an argument").

Pair the goal with success criteria. Show a strong example and a weak one. Ask students to describe the difference in their own words. Now they have a mental model they can use to judge their own work as they go.

Strategy 2: Ask Hinge Questions Mid-Lesson

A hinge question is a single, carefully designed question placed at a decision point in the lesson. The answer tells you whether to push forward or loop back. Good hinge questions have one defensible answer, distractors that map to specific misconceptions, and a quick response format — multiple choice, A/B/C/D fingers, or ABCD cards.

If most students get it right, you move on. If most miss it, you reteach. If responses are split, you have just learned exactly which misconception is in the room. This beats asking "any questions?" — a prompt that almost guarantees silence and tells you nothing.

Strategy 3: Use Exit Tickets to Surface What Stuck

In the last three minutes of class, ask one or two focused questions students answer on an index card or sticky note. Keep them tight: "Explain in one sentence why X happens" or "Solve this one problem." Read them between classes. The next lesson opens with the patterns you found.

Exit tickets work because they give you data without the pressure of a graded quiz. Students take risks. You see thinking. And you walk into tomorrow's lesson with a plan grounded in actual evidence, not vibes.

Strategy 4: Ditch Hands-Up

When teachers ask a question and call on volunteers, the same four students answer every time. Everyone else opts out of thinking. Replace hands-up with random selection: name sticks, a class list with a randomizer, or simply a quick circle around the room.

The shift is uncomfortable for a week. Then it changes the classroom. Students prepare to think because they might be called on. Wait time goes up. The quality of answers — and the data you collect on who actually understands — improves dramatically.

Strategy 5: Mini-Whiteboards for Whole-Class Checks

Give every student a small whiteboard. Ask a question. Everyone writes the answer. On your count, they hold it up. You scan the room in five seconds and know exactly how the class is doing.

This is the closest thing to mind-reading available in a classroom. It surfaces what every student thinks at once, not just the loud ones. Use it for vocabulary, equations, dates, sentence fragments, quick sketches. It pairs well with hinge questions.

Strategy 6: Activate Peers as Instructional Resources

Wiliam calls this one of the five key strategies because peers can give feedback in real time at a scale no teacher can match. Structured peer review works best: give students a clear rubric, model the feedback you want, and have them respond to a specific element of each other's work.

"Two stars and a wish" is a classic format — two things that worked, one thing to improve. Pair it with a revision step so feedback leads to action. The benefit cuts both ways: giving good feedback forces students to internalize the success criteria.

Strategy 7: Build Self-Assessment Habits

The end goal of formative assessment is students who can do it themselves. Teach them to compare their work to success criteria before submitting it. Use traffic-light self-rating: red means I am lost, yellow means I am partway there, green means I have it.

Pair self-assessment with metacognitive prompts. "What part of this was hardest?" "What would you do differently next time?" Over months, students develop the habit of monitoring their own understanding — a skill that pays off long after your class ends. Our guide on metacognition for students goes deeper on this.

How to Start Without Burning Out

You do not need to overhaul your practice next Monday. Pick one strategy and try it for two weeks. Exit tickets are the easiest entry point because they take three minutes and give you immediate, useful data. Once that feels automatic, add a second technique.

The teachers who succeed treat formative assessment as a habit, not a project. Small, consistent moves compound. Wiliam and Thompson's research on teachers who adopted these strategies over six months found a mean effect size of 0.32 — and noted that most of the gains came at the end, after the practices became second nature.

Where AI Tutoring Fits In

Formative assessment runs into a real ceiling in a classroom of 30 students. You cannot have a one-on-one diagnostic conversation with every student every day. This is where AI tutoring helps. Platforms like LEAI give every student a personalized conversation partner that adapts to their pace, surfaces misconceptions, and asks follow-up questions instead of just giving answers.

For teachers, this means students get formative feedback continuously, not only when you can get to them. It complements your in-class strategies rather than replacing them. For more on this, see our teacher's guide to AI tutoring in the classroom. You can see plans, including the free School Plan for teachers and students.

Frequently Asked Questions

What is the difference between formative and summative assessment? Formative assessment happens during learning and is used to adjust teaching. Summative assessment happens at the end of a unit and is used to measure achievement. Formative is for learning, summative is of learning.

How often should I use formative assessment in a lesson? Continuously. Strong formative practice means checking understanding every few minutes, not only at the end. Hinge questions, mini-whiteboards, and quick checks should be embedded throughout the lesson.

Does formative assessment need to be graded? No. In fact, grading often undermines it. The point is to gather evidence and give feedback that moves learning forward. Once you attach a grade, students focus on the mark rather than the learning.
