MYP Command Terms: Match Depth, Score Higher

Quick answer: In MYP assessments, every command term sets a specific depth of response — called a depth ceiling. State a fact for State. Build a cause-effect chain for Explain. Weigh both sides and reach a verdict for Discuss. Matching that depth exactly, not maximizing it, is what separates a level 3–4 from a level 7–8.

You knew the content. You revised the topic. You wrote a full paragraph. And you still came back with a 4.

That result isn't a knowledge problem. It's a structure problem — and it's one of the most common reasons MYP students lose marks they've already earned.

Here's what's actually happening. Every MYP question contains a command term (the instructional verb that tells you what to do — Explain, Discuss, State, and so on). That term doesn't just describe a style. It sets the exact depth of response the examiner is looking for. Answer below that depth and you miss marks. Answer above it and you waste time on reasoning that wasn't asked for and won't earn you anything extra.

The skill isn't knowing more. The skill is reading the command term first, identifying the required depth, and writing precisely to that level — no shallower, no deeper.

This post breaks down the four depth tiers, shows you exactly what they look like in two real subject areas, names the most common mistakes students make, and gives you a quick checklist you can run through before you write a single word.

What Does "Depth Ceiling" Mean in MYP Assessments?

The IB MYP uses command terms to signal the cognitive level required by a question. These are not stylistic preferences or rough guidelines. Each term has a precise official definition, and MYP markschemes are written around those definitions.

The depth ceiling is the upper boundary of what a question is asking for. A State question has a low ceiling — a fact or a value, nothing more. A Discuss question has a high ceiling — multiple arguments, a counter-consideration, and a supported conclusion. When you answer a State question with a full explanation, you haven't done extra work. You've answered a different question. The marks aren't there for you to collect.

Matching depth precisely is the skill. Every time.

The Four Depth Tiers: A Framework for MYP Command Terms

MYP command terms group naturally into four tiers. Each tier corresponds to a level of thinking in the MYP assessment framework — from simple recall at the base to reasoned judgement at the top.

Tier	Command Terms	MYP Skill Level	What Your Answer Must Do
Tier 1 — Recall	State, List, Identify, Define, Label, Write down	Knowing	Give a fact, name, or value. No "because." No explanation.
Tier 2 — Account	Describe, Outline, Summarize, Annotate	Understanding	Show what or how — features, sequence, or pattern. No causes unless asked.
Tier 3 — Reasoning	Explain, Justify, Interpret, Apply, Demonstrate	Analysing	Build a cause-effect chain. Every claim must be linked to its outcome with "because" or "therefore" logic.
Tier 4 — Judgement	Discuss, Evaluate, Comment, Formulate	Evaluating	Weigh multiple factors or perspectives against each other. End with an explicit, supported conclusion.

One rule cuts across all four tiers: a Tier 1 question answered at Tier 3 depth earns the same marks as a Tier 1 answer — and costs you minutes you can't get back.

A Closer Look at Each Tier

Tier 1 — Recall

The question wants one thing: a specific name, value, or fact. Define, State, and List all sit here. No mechanism. No reason. If you find yourself writing "because," stop — you've drifted into Tier 3 territory that nobody asked for.

Tier 2 — Account

Describe and Outline questions want a picture of what something looks like or how it works. You're telling a story of features or sequence, not explaining why those features exist. A strong Tier 2 answer covers the key characteristics clearly. A weak one either skips features or sneaks in causes that lift it into Tier 3 without the marks to match.

Tier 3 — Reasoning

This is where most marks are lost. Explain questions don't just want a description — they want a mechanism. Every claim in a Tier 3 answer needs to be connected to its outcome. Water moves → because of a gradient → therefore the cell changes. That chain is what earns criterion levels at this tier.

Tier 4 — Judgement

Discuss and Evaluate questions require the full structure: an argument, a counter-argument or limiting condition, and a conclusion that explicitly weighs the two. One-sided answers that end without a verdict will not reach the top level bands, regardless of how accurate the content is.

Worked Example 1 — Science: What Does "Explain" Actually Require?

Question: "Explain why osmosis causes plant cells to become turgid."

This is a Tier 3 question. The command term is Explain, which — per the official IB MYP definition — requires "a detailed account including reasons and causes." A description of what happens is not enough.

---

Level 3–4 answer:

Osmosis is when water moves through a selectively permeable membrane from an area of high concentration to an area of low concentration. When this happens in a plant cell, the vacuole fills with water and the cell becomes turgid.

What's missing: This is a Tier 2 (Describe) response. It names the process and describes what happens, but it never explains why it happens. There is no water potential gradient, no mechanism linking the concentration difference to water movement, and no account of the opposing force that creates turgor. The vocabulary appears but doesn't do any work — it's name-dropped, not applied.

---

Level 7–8 answer:

The cell's vacuole contains a concentrated solution with a lower water potential than the surrounding fluid. Because water moves by osmosis down a water potential gradient — from higher water potential outside to lower water potential inside — water enters the cell through the tonoplast and plasma membrane. As the vacuole fills, the cell contents expand and press outward against the rigid cell wall. The cell wall exerts an equal and opposite inward pressure (turgor pressure), which resists further expansion. The cell becomes turgid when the turgor pressure balances the water potential difference driving inflow. This turgor is what gives non-woody plant tissue its structural rigidity.

What changed: Every claim is followed immediately by its reason. "Water enters" → because of a named water potential gradient. "The cell wall resists" → because it generates a measurable opposing force. The scientific vocabulary (water potential, tonoplast, turgor pressure) is used to explain a mechanism, not simply to demonstrate that the terms were memorized. That's the difference Explain demands.

Worked Example 2 — Individuals & Societies: What Does "Discuss" Actually Require?

Question: "Discuss the effectiveness of trade protection in reducing a country's trade deficit."

This is a Tier 4 question. The command term is Discuss, which — per the official IB MYP definition — requires "a considered and balanced review including a range of arguments, factors or hypotheses; conclusions supported by appropriate evidence."

A one-sided answer, however accurate, does not meet this definition.

---

Level 3–4 answer:

Trade protection such as tariffs and quotas can reduce imports, which lowers the trade deficit. Tariffs raise the price of foreign goods, so consumers buy fewer imports. This means the trade deficit is effectively reduced through trade protection.

What's missing: This answer explains one mechanism reasonably well — it has a causal chain (tariffs → higher prices → fewer imports → narrower deficit). But it treats that mechanism as the full picture. There is no limiting condition, no counter-consideration, and no explicit judgement that weighs the argument against its complications. It reads like a Tier 3 (Explain) answer dressed up as a Discuss response.

---

Level 7–8 answer:

Tariffs raise the domestic price of imported goods, prompting consumers to substitute domestic alternatives. Import volume falls and, with it, the trade deficit narrows. This mechanism can be effective in the short run. However, its impact depends heavily on the price elasticity of demand for imports: if demand is inelastic — as it often is for essential goods with few domestic substitutes — spending on imports may not fall significantly even as prices rise, limiting the deficit reduction. A further complication is retaliation: trading partners hit by tariffs may respond with their own barriers, reducing the country's export revenue and potentially widening the deficit through a different channel. On balance, trade protection can reduce a trade deficit when import demand is elastic and trading partners do not retaliate. Where those conditions do not hold, its effectiveness is limited and the net effect on the deficit may be negative.

What changed: The answer follows a four-part structure that Discuss requires: (1) a named mechanism, (2) a limiting condition tied to a specific economic concept (price elasticity), (3) a counter-consideration (retaliatory tariffs), and (4) an explicit qualified judgement that weighs both sides. That four-part shape is not optional at Tier 4. It's the structure the examiner is marking against.

Common Mistakes — and the One-Sentence Fix for Each

Describing when asked to Explain

You give a clear account of what happens but never say why. Fix: After every claim, ask yourself "why does this happen?" and answer it before moving on.

Explaining when asked to Describe

You spend time building cause-effect chains that the question didn't ask for. Fix: Check the tier before you write — if the command term is Tier 2, stop at the "what," not the "why."

Answering Discuss or Evaluate with only one side

You present a strong argument, then stop. Fix: Every Tier 4 answer needs a counter-consideration and a closing judgement — write those two elements last, every time, without exception.

Ignoring mark allocation as a depth and length signal

A 2-mark question wants a phrase or a single sentence, not a paragraph. Fix: Divide the marks by two to estimate the number of distinct points needed, then match your length accordingly.

Treating "more content" as automatically better

Length doesn't earn marks. Content earns marks only when it does a job — clarifying a cause, supporting an inference, building an argument. Fix: Before writing a sentence, ask: what criterion level does this sentence serve?

Your 30-Second Pre-Writing Checklist

Run through this before you write anything.

• What is the command term? Write it down.
• Which tier does it belong to? Recall, Account, Reasoning, or Judgement?
• What does a top-band answer in this tier look like? Name the structure — fact only, features and sequence, cause-effect chain, or multi-sided judgement.
• Am I about to under-answer or over-answer? Under-answering means missing reasoning. Over-answering means adding unrequested justification to a Tier 1 or Tier 2 question.
• Does my planned length match the mark allocation? A two-mark question and a ten-mark question are not the same task.

That's the whole pre-flight. Thirty seconds. Do it before every question.

Structure Is a Skill. You Can Learn It.

Content knowledge matters. But content without structure is raw material that never gets built into anything the examiner can award.

The depth-matching framework covered in this post is repeatable and learnable. Once you know which tier a command term belongs to, and you know what each tier's answer must contain, the guesswork disappears. You're not trying to write "more" or "better" in some vague sense. You're hitting a defined target.

If you want to check whether your answers are actually landing at the right depth, Koncepts' Homework Help includes an Analyse mode built specifically for this. Once you've written a finished answer, Analyse mode reviews it sub-question by sub-question against the markscheme and the command term it was written for — showing you exactly where your depth was under-matched, over-matched, or on target. No guessing about what went wrong. A precise diagnosis, tied to the criterion level, every time.

Frequently Asked Questions

What are MYP command terms and why do they matter for scoring?

MYP command terms are the instructional verbs in assessment questions — State, Describe, Explain, Discuss, Evaluate, and others. Each has a precise official IB definition. They matter because MYP markschemes are written directly around those definitions. Answering at the wrong depth — too shallow or too detailed — means your answer doesn't match what the examiner is marking against, regardless of how accurate your content is.

What is the difference between Describe and Explain in MYP?

Describe (Tier 2) requires a detailed account of what something looks like or how it works — features, sequence, or pattern — without causes. Explain (Tier 3) requires "a detailed account including reasons and causes." An Explain answer must contain a cause-effect chain linking mechanism to outcome. Giving a description when asked to explain is one of the most common reasons students lose marks.

What does a Discuss answer need to include in MYP?

A Discuss answer (Tier 4) must include: a named argument or mechanism, at least one limiting condition or counter-consideration, and an explicit conclusion that weighs both sides. The IB MYP official definition requires "a considered and balanced review including a range of arguments, factors or hypotheses; conclusions supported by appropriate evidence." One-sided answers without a closing judgement will not reach the top level bands.

Does writing more always earn higher marks in MYP?

No. Length only earns marks when each sentence does a specific job — clarifying a cause, supporting an argument, or meeting a criterion descriptor. A long answer that repeats the same point at different levels of detail will not outscore a shorter, structurally correct answer. Mark allocation is the best signal for how much to write: a 2-mark question needs a phrase or a brief sentence, not a paragraph.

How do I know which depth tier a command term belongs to?

Check the four tiers: State, List, Identify, Define → Tier 1 (Recall). Describe, Outline, Summarize, Annotate → Tier 2 (Account). Explain, Justify, Interpret, Apply, Demonstrate → Tier 3 (Reasoning). Discuss, Evaluate, Comment, Formulate → Tier 4 (Judgement). When in doubt, look up the official IB MYP definition — the definition will tell you whether causes, reasons, or a balanced conclusion are required.

Can I check my MYP answers against a markscheme before submitting?

Yes. Koncepts' Analyse mode reviews a completed answer sub-question at a time, checking it against the markscheme and the command term the question was written for. It shows specifically where depth was under-matched or over-matched — not a vague score, but a precise breakdown tied to the criterion level.
