How to Use Formative Assessment

The short answer: you use formative assessment by checking understanding during learning with quick, low stakes techniques, then using the result to adjust your teaching before the summative test. The check is only useful if it changes what happens the next day.

Most teachers think they are formatively assessing when they hand back a graded quiz. That is summative feedback, which arrives too late to reshape the unit. Formative assessment is the ongoing read you take while the door is still open.

Formative Assessment at a Glance

Know the Difference From Summative

Formative assessment happens while learning is still open. Its job is to inform, not to score. A summative test closes the book and assigns a mark. Mixing the two confuses students, who then hide mistakes to protect a grade.

Keep formative low stakes on purpose. When the score is off the table, students show you what they actually think, which is the data you need.

The research base here is unusually strong. Black and Wiliam reviewed roughly 250 studies and concluded that improved formative assessment can raise achievement, with effect sizes in the reviewed experiments typically between 0.4 and 0.7, larger than many educational interventions Black & Wiliam, "Inside the Black Box". Their later classroom work found that better questioning, feedback focused on improvement rather than grades, and student self assessment raised test scores versus comparison groups Black et al., "Working Inside the Black Box". The practical point: the technique matters, but using the result matters more.

Use Quick Exit Checks

The simplest method is the exit check. Before students leave, ask one question that targets the day's goal and have them write the answer. Scan the responses in a minute. If most miss it, you reteach tomorrow. If most get it, you move on.

This costs almost no time yet gives a clearer picture than a gut feeling about the room. A written exit check also surfaces the quiet student who would never raise a hand.

Try Verbal and Visual Signals

Not every check is on paper. A show of hands, a thumbs up or down, or holding up a card with A or B turns the whole class into a signal. These are fast and let you spot the silent student who would otherwise slip through.

Use them mid explanation so you can pivot in the moment, not after the lesson ends. The signal is only formative if it changes the next five minutes of teaching.

Apply the Result Immediately

A check with no follow up is wasted motion. The power is in the adjustment. If a third of the class misses a step, reteach it in a new way. If one student is lost, pull a small group. The loop is check, decide, act.

This is where formative assessment feeds differentiation, since the evidence tells you which group needs which task. Without the adjustment step, you have collected data and done nothing with it.

Use Spaced Checks for Trends

A single check is a snapshot. Spaced checks catch forgetting that one test misses. Repeating the same skill across several lessons, with fresh questions each time, shows whether a class has truly retained the idea or just memorized Tuesday's example.

The repetition also models for students that retrieval is not a one time event. When the question returns next week, they learn that the material is expected to stick, not just to be filed.

Common Misconceptions

• "Grading the check makes it serious." It shifts behavior from honesty to score protection, which destroys the signal.
• "Checking only at the end is fine." The chance to adjust is gone by then.
• "Ignoring the result saves time." A check with no action teaches nothing new.
• "Long quizzes are more accurate." Heavy formats turn formative into summative by feel and burn the time the technique is meant to save.
• "It requires special tools." A question on the board and a quick read of answers is enough to start.

Frequently Asked Questions

How often should I formatively assess?

Briefly, most days. A one minute check beats a weekly quiz for catching confusion early, when there is still time to act.

Is a homework review formative?

It can be if you use it to adjust, though homework is often completed with help, which muddies the signal. Pair it with in class checks for a clearer read.

Do I need special tools?

No. A question on the board and a quick read of answers is enough to start.

How does this connect to feedback?

Formative checks create the moment for feedback. The check shows the gap; the feedback tells the student how to close it. Without the check, feedback is guessing.

What if the whole class misses the point?

That is the win of formative assessment. You learn it now, before the test, and reteach while it still counts.

Can a student use this alone?

Yes. Self quizzing and correcting your own work is formative assessment turned inward. The same rule applies: the check only helps if you act on what it shows.
