ABCD Response Cards

The strategy, as published

Exactly as it appears on the card

Part of Elicit Evidence of Learning in 02 Formative Assessment, where it sits alongside its neighbouring strategies, the infographic and the thinking for the whole area.

Why you might use it

The problem it may help with

Four cards per pupil, one question, every answer in the air at once. The routine costs almost nothing, and what it buys is the thing this strand keeps returning to: a response from everyone, not a guess about the room built from three raised hands.

No hands, no opt-out also changes what answering feels like. Nobody is volunteering; everyone is simply answering, which lowers the cost of being wrong in front of others.

What it might look like

One version of it, in a classroom

A geography teacher poses a four-option question on reading a population pyramid. On a count of three, thirty cards go up. A visible cluster on option C, the misread axis, decides what gets explained next.

Try it

A way to begin

A class set costs one preparation session: print, laminate if you like, keep them in the room. Start with a single question at one checkpoint tomorrow.

What to notice

Reading what happens

• The spread, not just the most common answer. A room split two ways needs different teaching from a room that is mostly right.
• Pupils who glance sideways before raising their card. Simultaneity is what protects the evidence.

Things to think about

Before and while you use it

• The question has to deserve the routine. Four options invite properly engineered distractors; a question with three filler answers wastes the whole-class machinery.
• Cards suit selected response. When you need to see working or prose, mini whiteboards or another route to the same full visibility does that job.

Where this connects

• ✍️ Mini Whiteboards All students write their response and hold it up simultaneously. The teacher reads the room in seconds: full participation, no waiting, no dominant voices. Works across all subjects. 02 Formative Assessment · Elicit Evidence of Learning
• 🧩 Plausible Distractors Engineer wrong answers as carefully as the right one. Each distractor should map to a real misconception. Every wrong answer a student gives tells you something precise. Wrong answers are the diagnostic data. 02 Formative Assessment · Elicit Evidence of Learning
• 🔀 Hinge Questions A hinge question is a diagnostic question at a lesson turning point. Wrong answers each map to a known misconception. Responses tell you whether to move on or go back. Never improvise it. 02 Formative Assessment · Elicit Evidence of Learning
• 🌎 Every Voice, Every Time Eliciting evidence only works if every student can respond. Offer written, verbal, visual and digital means of expression. The method you choose decides who gets to show what they know. 02 Formative Assessment · Elicit Evidence of Learning

Inclusive practice

The lens this connects with

Through the inclusive practice lens, this is one of the approaches that may reduce barriers around:

• Access and participation

The wider thinking

Where the evidence sits

All-student response is one of Wiliam's staple techniques for eliciting evidence: the next teaching decision gets made on the whole room, not a sample of it. The card’s attribution stands as published: Wiliam.
