IB DP Subject Mastery: The ‘Command Term Bank’ That Improves Essays Across Subjects

IB DP Subject Mastery: The ‘Command Term Bank’ That Improves Essays Across Subjects

Ever opened a paper, read the first line, and felt your heart sink because you weren’t sure what the question was actually asking? You’re not alone. In the IB Diploma Programme, the difference between a good answer and a top-mark response often comes down to one thing: how precisely you respond to the command term. The good news: command terms are learnable, practiceable, and massively transferable across subjects.

This post walks you through a living, usable Command Term Bank — a practical toolkit you can carry from physics practicals to history essays, from math papers to language analyses. You’ll get definitions, clear strategies, paragraph starters, subject-by-subject examples, and a ready-to-use practice plan. Sprinkle in short, targeted practice and your answers will start matching what examiners are actually looking for.

Why command terms matter (and why they are your secret study lever)

Command terms are not just vocabulary; they are instructions. They tell examiners what cognitive move you must make: describe, compare, analyze, evaluate, justify — each word maps to a different depth of thinking and a different shape of response. If you treat every prompt as an essay-in-waiting without checking the command term, you risk writing the wrong kind of answer — long, impressive, and low-scoring.

Think of command terms as the blueprint the examiner gives you. Respond to the blueprint accurately and you’ll score the marks the rubric awards. Misread it and you might win style points but lose marks for relevance and assessment criteria.

How to use this Command Term Bank

• Underline the command term first. Everything follows from that single move.
• Identify limits (timespan, location, specific case studies) and command modifiers (compare, for example).
• Plan a skeleton answer: thesis/claim, 2–3 evidence points, short analysis, and clear link back to the command term.
• Use the sentence starters in this post to shape each paragraph so it answers the task, not just the topic.

Core Command Terms: Short Definitions and Strategies

Below is a compact bank of essential command terms, what they expect you to do, and quick strategies you can apply immediately. Keep this table as a printable cheat-sheet when you practice past papers.

Reading a Question Like a Pro

Don’t rush. In timed papers, the pressure is real, but a 60–90 second investment in careful reading can save several marks. Follow this quick routine every time you see a question:

• Spot the command term: Circle it immediately.
• Identify scope: List any named theories, case studies, years, or limits in the question box.
• Note the required depth: Is it a ‘describe’ or an ‘evaluate’? That decides the paragraph shape.
• Plan 2–3 evidence points: Jot them down. Don’t fully write — just anchors.
• Allocate time: Mark how many minutes you’ll spend outlining vs. writing vs. reviewing.

That last point matters: examiners reward quality over quantity. A focused, relevant paragraph that directly answers the command term will often beat a long, meandering one.

Subject-Specific Uses: How the Same Command Term Looks Different in Each Subject

Command terms are portable, but the evidence you use and the way you argue change with the subject. Here are tight examples so you can feel how to shift gears.

Sciences (Biology, Chemistry, Physics)

Command term: “Explain” — In sciences this often expects cause-and-effect plus mechanistic detail. If a question asks you to “explain how X leads to Y”, your paragraph should name the mechanism, describe the steps, and note any qualifiers (conditions, assumptions, limitations).

Example structure:

• Topic sentence: “X causes Y by…”
• Mechanistic detail: key steps, formulas, or diagrams referenced.
• Evidence: experimental results or accepted theory.
• Limitations: where the mechanism may not apply or assumptions made.

Mathematics

Command term: “Solve” or “Calculate” — Precision and correct method are everything. Show your working — even partial credit can be crucial. If the term is “prove”, you must demonstrate logical steps and justify each inference.

Strategy: write a clear starting line referencing known theorems, then proceed step-by-step, labeling substitutions and concluding explicitly.

Language A (Essays and Textual Analysis)

Command term: “Analyse” — Focus on language, structure, and literary devices. Don’t summarize the plot; interpret how specific features create meaning and link them to the prompt.

Example starter: “The writer’s use of [device] in [passage] highlights… which suggests…”

Individuals & Societies (History, Economics)

Command term: “Assess” or “Discuss” — Balance is key. Present supporting and opposing evidence, weigh reliability of sources, and reach a conclusion that answers the precise question, not a general theme.

Tip: use short, evidence-focused paragraphs with explicit linkage back to the command term: “This evidence supports X because…”

Arts and Design

Command term: “Evaluate” or “Justify” — Critically appraise artistic choices, materials, methods, and intended meanings. Tie evaluation to criteria such as coherence with the brief, originality, and technical skill.

Example: “Against the criterion of technical control, the artist achieves…; however, in terms of innovation…”

Paragraph Templates: Turn Command Terms into Ready-to-Use Moves

Memorize one strong template for each major command term and adapt it quickly in the exam. Templates reduce decision fatigue and keep answers focused on what the marker wants.

Analyse (three-sentence template)

Topic sentence that identifies the part to analyse and the method: “X can be analysed in terms of A because…” Evidence and explanation: “For example,… which shows…” Mini-conclusion that links back to the question: “Therefore, X leads to Y by…”

Compare (two-paragraph template)

Paragraph 1 — Similarities: “Both X and Y… This is significant because…” Paragraph 2 — Differences and importance: “However X differs from Y in that… which means…” Conclude by weighing the more decisive factor relative to the question.

Evaluate (four-part template)

1. State criteria for judgment.
2. Assess evidence for and against each criterion.
3. Weigh the strengths and limitations.
4. Conclude with a justified, balanced judgment.

Sentence Starters & Linking Phrases (Use them to answer the command term, not to pad)

• For explanation: “This is because…”, “Consequently…”, “The underlying mechanism is…”
• For analysis: “This suggests that…”, “An important implication is…”
• For comparison: “Similarly…”, “In contrast…”, “A key difference is…”
• For evaluation: “On the one hand…”, “However, limitations include…”, “Therefore, it is more accurate to…”

Practice Plan: Build Your Bank in 6 Weeks of Deliberate Practice

Deliberate, repeated practice beats last-minute cramming. Here is a focused cycle you can repeat over several weeks. The key: active retrieval and timed responses.

• Week 1: Make flashcards of 20 core command terms. For each, write the definition on one side and a 20–30 word strategy on the other.
• Week 2: Do topic drills: pick one command term per subject and answer two short past-paper questions under timed conditions.
• Week 3: Peer review: swap answers and annotate whether the command term was answered directly; give a one-sentence suggestion.
• Week 4: Mixed practice: three exercises in one session, each from a different subject — focus on switching cognitive modes quickly.
• Week 5: Mock timed paper: emphasize planning time (2–3 minutes for each long-response question) and use the paragraph templates.
• Week 6: Reflection and refinement: list the command terms you still hesitate over and create example answers for them.

Some students combine this with targeted tutoring. If you want tailored, one-on-one guidance to sharpen interpretation and feedback on practice answers, Sparkl‘s personalized tutoring can offer focused coaching, tailored study plans, expert tutors, and AI-driven insights to speed improvement.

Command Terms and Extended Work (EE & IA): Where Marks Multiply

Extended responses like the Extended Essay or Internal Assessments include assessment criteria that function like command terms. When a rubric asks you to “evaluate”, it expects a sustained, criterion-based judgement; when it asks you to “analyze data”, it expects methodical, replicable steps.

Practical tip: before you write a section in your EE or IA, write the command term of the criterion at the top of the page and list 2–3 bullets that will satisfy that criterion. This keeps your writing targeted and prevents tangents that look impressive but fail to meet rubric demands.

When you need help turning draft paragraphs into responses that map directly to assessment criteria, a tutor who understands IB marking can speed that improvement; consider short, focused sessions that target specific rubrics and command-term alignment.

Common Mistakes and How to Fix Them

• Answering the topic instead of the term: Fix by rephrasing the command term as a question and writing one-line thesis that directly answers it.
• Over-explaining for a low-order command term (e.g., ‘outline’): Fix by keeping answers concise and focused on main points.
• Under-evidencing for high-order terms (e.g., ‘evaluate’): Fix by stating criteria and using explicit evidence to support judgments.
• Poor time allocation: Fix by planning at least 1–3 minutes per long-answer to map evidence to the command term before writing.

Quick self-check before you submit any answer

• Does my first sentence directly respond to the command term?
• Have I used evidence or examples to support any claim made?
• Does each paragraph link back to the command term? (A short linking sentence helps.)
• If the term asks for judgment, have I stated criteria and weighed evidence?

Putting It All Together: A Worked Example

Question (History-style): “To what extent was economic policy the main cause of social unrest in region X?” Command term: “To what extent” = assess degree and significance.

Fast plan (3 minutes):

• Define the criterion: degree of causation vs. other causes (political, cultural).
• Evidence 1: Economic data showing unemployment spike — discuss impact.
• Evidence 2: Political repression records — discuss as alternative cause.
• Weigh and conclude: economic policy was a major factor but insufficient alone.

Answer skeleton (use in your exam): Topic sentence that answers the command term directly, two evidence-led paragraphs each ending with a sentence linking back to the degree of causation, concluding paragraph that weighs evidence and gives a nuanced judgment.

Final Notes: Make the Bank Your Habit

Treat the Command Term Bank as a muscle: short, frequent workouts beat one marathon study session. Build a set of flashcards, practice under timed conditions, and force yourself to write the first sentence so it answers the command term. Over time you’ll reduce those exam-day moments of uncertainty and gain more control over what the examiner reads.

Mastering command terms turns prompts from vague assignments into clear blueprints for responses that meet marking criteria. Keep practicing deliberately, map your evidence to the specific instruction every time, and let the command terms guide both your planning and your writing.
