A unit test tells you what students learned after the teaching is over. Formative assessment tells you while there is still time to do something about it. It is not a type of test; it is any moment where you collect evidence of learning and use it to decide what happens next.
In their 1998 review "Inside the Black Box," Paul Black and Dylan Wiliam brought together hundreds of studies and concluded that strengthening formative assessment produces some of the largest learning gains of any classroom change, with the biggest benefits for students who struggle most. The key word is use: a check that does not change your next move is just a quiz.
What makes a good quick check
- It is fast. Two to five minutes, so you can run one every lesson.
- Every student answers. Not just the three hands that always go up.
- The answers are easy to read at a glance. You should know within a minute where the class stands.
- It targets one idea. A check that covers everything tells you nothing specific.
Twelve checks you can run tomorrow
1. Exit ticket
One or two questions on a slip of paper at the end of the lesson. Sort the slips into three piles (got it, almost, not yet) and plan the first ten minutes of tomorrow around the middle pile. We have a whole post of exit ticket ideas.
2. Hinge question
A single multiple-choice question at the turning point of a lesson, where each wrong option matches a specific misconception. If most students pick the right answer, move on; if a cluster picks the same wrong option, you know exactly what to reteach.
3. Show-me boards
Mini whiteboards or scrap paper held up at the same time. Everyone answers, and you see thirty answers in three seconds.
4. Fingers or letter cards
For multiple-choice questions, students hold up one to four fingers or an A–D card. It costs nothing and works in any room.
5. One-minute paper
"What was the most important idea today, and what is still unclear?" The second half is where the gold is.
6. Muddiest point
Ask only for the part that confused them most. Patterns appear quickly, and students learn to name their own confusion.
7. Odd one out
Show four items, such as numbers, words or diagrams, and ask which does not belong and why. The reasons reveal more than the choice.
8. Error analysis
Show a worked example with a deliberate mistake. Students who can find and fix it understand the procedure; students who cannot are following steps by memory.
9. Rank your confidence, then answer
Students rate how sure they are before answering a question. Confident wrong answers point to misconceptions worth addressing head-on.
10. Quick-write summary
Three sentences, no notes: what we learned, why it matters, one example. Read a handful and you will know whether the main idea landed.
11. Three-question quiz
One recall question, one application question and one question from last week. Short enough to mark in minutes, and the third question doubles as spaced review.
12. Concept map in five minutes
Give students five key terms and ask them to connect them with labeled arrows. Missing or wrong links show which relationships have not clicked yet.
Acting on what you find
The check is the easy part. The decision afterward is what makes it formative:
| What you see | What to do next |
|---|---|
| Most students got it | Move on; give the few who did not a short follow-up task. |
| Half and half | Pair students who got it with those who did not for a five-minute explanation. |
| Most students missed it | Reteach with a new example or angle, not the same explanation louder. |
| Everyone chose the same wrong answer | You have found a misconception. Address it directly. |
Keep it low stakes
Formative checks work best when students see them as information, not judgment. Mark them for feedback rather than grades, and tell students why you are asking: "This tells me what to teach tomorrow." Students answer more honestly when a wrong answer cannot hurt them.
Saving prep time
The slowest part of a three-question quiz or a hinge question is writing good questions. Quizbot can draft them from your slides, a textbook page or your own notes with the AI quiz generator, so you spend your time choosing and adjusting questions instead of writing them from scratch.
Summary
- Formative assessment is evidence you use to decide your next move.
- Pick quick checks where every student answers and you can read the results at a glance.
- Decide in advance what you will do for each pattern of answers.
