Five Formative Assessment Techniques That Work in Every Subject and Every Class Size

By [Author name, credentials needed] · Reviewed for School of Educators

Key facts

• Formative assessment does not require testing. It requires frequent, specific evidence of what students actually understand, gathered through observation, questioning, and brief tasks.
• The techniques below are free, fast, and drawn from research associated with formative assessment work by researchers including Dylan Wiliam and Paul Black, applicable across subjects and class sizes.
• NEP 2020, NCF 2023, and the NIPUN Bharat foundational literacy mission all point toward continuous, low-stakes assessment as the basis for adjusting instruction, not periodic testing alone.
• Free classroom resources: NIPUN Bharat FLN assessment tools (through your SCERT or DIET), NCERT teacher guides, Azim Premji Foundation’s open-access research, and DIKSHA platform content in 36 languages.
• Support for teachers: KIRAN mental health helpline (1800-599-0019), Tele-MANAS (14416), CHILDLINE (1098).

Formative assessment does not require testing. It requires frequent, specific evidence of what students understand, gathered through observation, questioning, and brief tasks, and used immediately to adjust what happens next in the lesson. Five techniques below are free, fast, and backed by consistent research, and every one of them can run in a 40-student government classroom or a small private one without extra materials or extra time carved out of the syllabus.

What the research actually says

Indian teachers already sense that the research on formative assessment is more specific and more useful than most professional development programmes suggest; it just rarely gets said aloud in a staffroom. The evidence here draws on ASER survey data, Azim Premji Foundation field studies, NCERT curriculum research, government programme evaluations, and peer-reviewed work conducted in government and private schools. Where international evidence is used, most notably the formative assessment research associated with Dylan Wiliam and Paul Black, it is noted explicitly and needs to be checked against Indian classroom conditions, particularly class size, before it is applied directly.

This is not an essay about education in Singapore or Finland, translated awkwardly into an Indian setting. It is written for teachers across subjects and stages, because these five techniques were chosen specifically for working in large, resource-constrained classrooms, not for the smaller classes and higher resourcing that much of the underlying international research was conducted in.

A teacher who genuinely cares can still make a problem worse by misunderstanding its mechanism. Understanding the mechanism is what turns sincere care into effective care.

Good intentions are not sufficient on their own. A teacher who asks “does everyone understand?” to a class of forty, out of a genuine wish to check comprehension before moving on, gets a room of nods that tells her almost nothing, because silence and nodding are the easiest response for a student who doesn’t want to be singled out as confused. The techniques below exist because that specific question fails as evidence, even when asked with good intentions. The gap between checking for understanding and actually gathering evidence of it is where the practical work below sits.

Five formative assessment techniques that work in every subject and class size

These five techniques recur across the research on formative assessment, and they hold up whether a class has fifteen students or fifty.

1. Exit tickets. In the last two minutes of a lesson, every student writes one sentence answering a specific question tied to that day’s content, then hands it in on the way out. Reading through them takes a few minutes and shows exactly which students, and which specific point, need revisiting tomorrow, evidence a show of hands never gives.

2. Cold-calling with wait time, not volunteer hands. Instead of asking a question and taking the first raised hand, a teacher poses the question, gives several seconds of silent thinking time, and then calls on a specific student by name. This surfaces understanding, or the lack of it, from students who would otherwise stay silent and let confident volunteers carry the whole class’s apparent comprehension.

3. Mini whiteboards or show-me signals. Every student writes a short answer, a number, a word, a symbol, on a small board or even a torn scrap of paper and holds it up on a signal. A teacher scans the whole room in seconds and sees the full spread of understanding at once, rather than hearing from one student at a time.

4. Think-pair-share with the teacher listening in. Students think silently, then discuss briefly with a neighbour, while the teacher circulates and listens to a sample of pairs rather than lecturing through the pause. The paired conversation surfaces reasoning a whole-class question rarely does, and listening in gives the teacher direct evidence rather than a guess based on who speaks up afterward.

5. One-sentence summary or muddiest point. At the end of a lesson or a section, students write one sentence summarising the main idea, or one sentence naming the part that confused them most. Both versions produce specific, actionable evidence in under a minute, without requiring a single test question to be written or marked in the traditional sense.

Where this fits Indian education policy

NEP 2020, NCF 2023, and the NIPUN Bharat mission all point in the direction this research supports: continuous, low-stakes assessment integrated into everyday teaching, rather than understanding checked only through periodic formal tests. The gap between that policy direction and what actually happens on a Tuesday morning, a quick “any questions?” before moving to the next topic, is the space this piece is trying to close. It is not an argument for a new policy. It is guidance for the teacher who is already in the room, deciding how to actually find out what the class understood.

Frequently asked questions

Do these techniques work in a class of forty or more students? Yes, and that scale is exactly why they were chosen. Exit tickets and whiteboard signals gather evidence from every student simultaneously rather than one at a time, which is what makes them usable in large Indian classrooms where individual questioning of every student isn’t practical.

How is this different from just asking “does everyone understand?” That question invites silence and nodding, which is the easiest response for a confused student who doesn’t want to be singled out. Each of the five techniques above produces a specific, individual piece of evidence, a written sentence, a whiteboard answer, a paired conversation overheard, rather than a vague public signal that tends to reflect confidence more than comprehension.

Do these techniques take significant extra class time? No. All five are designed to take a few minutes at most and to fit inside a lesson that’s already happening, rather than requiring separate assessment periods carved out of the syllabus.

Where can a teacher find state-specific material on this? Start with your SCERT or DIET for NIPUN Bharat FLN assessment tools, NCERT’s teacher guides, Azim Premji Foundation’s open-access publications, and DIKSHA, which carries content in 36 languages. If nothing exists for your specific state and grade, that gap is itself worth reporting to your Block Resource Coordinator.

What to do:

• Name one child in your class who would benefit most from more frequent formative checks, and write down one specific technique from above you will try with your class this week. Not a general improvement: a named technique, tried once, this week.
• Search DIKSHA or ask your Block Resource Coordinator for any resource specific to this topic in your state’s context. If nothing exists, note that and report it. The gap in resources is itself useful information.
• Spend five minutes this week just observing one aspect of your classroom related to this, not teaching, just watching and noting. What you notice while only watching is different from what you notice while teaching.
• Tell one colleague one specific finding from this piece this week. Explaining it will sharpen your own understanding, and it may start a conversation that helps more than any single action.
• At the end of the week, ask yourself what you will do differently next week because of this, and what you will look for to know whether it worked.
