A one-mark identification and a six-mark explanation should not receive the same amount of reasoning, writing or checking. Mark-Value Response-Depth Calibration turns the printed mark value into a planning signal: identify the likely credit-bearing units, build the minimum complete answer, then stop when the next sentence adds no new task-relevant work.
Use it now. Before writing, ask: what distinct work could this question reward—an answer, method, evidence, mechanism, comparison, qualification or judgement? Build those units visibly. Do not use “one sentence per mark” as a universal rule; actual subject logic, rubric, command word and current paper instructions remain in control.
The 2027 G2 directory lists English Language K200, Mathematics K210 and Science K223/K224/K225. These subjects award credit differently, so mark value is guidance rather than a mechanical word-count formula. Use the actual task, official specimen material where available and your school’s current instructions.

1. Read marks as opportunity, not a word quota
Mechanism. Read marks as opportunity, not a word quota. Make the controlling decision visible before compressing it into a fast routine. A visible decision can be inspected and corrected; an unspoken habit can produce a plausible response for the wrong reason.
Original worked example. A four-mark explanation may need cause, mechanism, consequence and evidence, not four sentences. The wording and values are created for teaching, not copied from an examination. Identify the cue, apply the relationship and state the conclusion at the precision the evidence supports.
Misconception diagnosis. The learner writes four long sentences that repeat one idea. Treat this as evidence about the first failed decision, not as a verdict on the learner. Mark that earliest unstable step so correct later work does not need to be rebuilt unnecessarily.
Repair. Name the different credit-bearing jobs before choosing length. Close the model and reproduce the decision from memory. Change one surface feature, then explain what remained invariant and why the method still fits.
Practice progression. Start untimed with the decision labelled. Remove the label, vary numbers or wording, add a strong near-neighbour distractor and finish with a short realistic time boundary. Record whether the learner chose the move independently.
Explained answer check. A secure answer preserves the governing relationship, relevant evidence, units or language strength, and the exact task demand. Compare assumptions with the prompt instead of choosing the most familiar method.
Transfer. Give a fresh item after a delay without naming this chapter. Success means the learner detects the same structure, completes the task and can justify the choice. If transfer fails, return to the earliest decision rather than adding identical repetition.
2. Secure the minimum complete answer
Mechanism. Secure the minimum complete answer. Make the controlling decision visible before compressing it into a fast routine. A visible decision can be inspected and corrected; an unspoken habit can produce a plausible response for the wrong reason.
Original worked example. A comparison needs both items and an explicit relationship. The wording and values are created for teaching, not copied from an examination. Identify the cue, apply the relationship and state the conclusion at the precision the evidence supports.
Misconception diagnosis. The response describes only one side in detail. Treat this as evidence about the first failed decision, not as a verdict on the learner. Mark that earliest unstable step so correct later work does not need to be rebuilt unnecessarily.
Repair. Complete every compulsory answer unit before adding polish. Close the model and reproduce the decision from memory. Change one surface feature, then explain what remained invariant and why the method still fits.
Practice progression. Start untimed with the decision labelled. Remove the label, vary numbers or wording, add a strong near-neighbour distractor and finish with a short realistic time boundary. Record whether the learner chose the move independently.
Explained answer check. A secure answer preserves the governing relationship, relevant evidence, units or language strength, and the exact task demand. Compare assumptions with the prompt instead of choosing the most familiar method.

Misconception diagnosis. The learner judges quality by lines filled. Treat this as evidence about the first failed decision, not as a verdict on the learner. Mark that earliest unstable step so correct later work does not need to be rebuilt unnecessarily.
Repair. Ask what new inferential work each line performs. Close the model and reproduce the decision from memory. Change one surface feature, then explain what remained invariant and why the method still fits.
Practice progression. Start untimed with the decision labelled. Remove the label, vary numbers or wording, add a strong near-neighbour distractor and finish with a short realistic time boundary. Record whether the learner chose the move independently.

A seven-day practice plan
Day 1: learn the distinction and complete two guided examples.
Day 2: diagnose three deliberately flawed responses.
Day 3: practise a varied set without chapter labels.
Day 4: explain one answer aloud and shorten the explanation without losing its reason.
Day 5: use a timed mini-set and record the first failed decision.
Day 6: repair that decision, then attempt a changed transfer item.
Day 7: complete a delayed mixed check and write one next-step target.
Final learner checklist
□ I can state the exact task before I start.
□ I can identify the decision that controls the later steps.
□ I can show enough working or notes to make that decision visible.
□ I can diagnose the first wrong step instead of only comparing final answers.
□ I can complete a changed example without copying the model.
□ I follow current paper and school instructions rather than treating this guide as an examiner rule.
