In IB examinations, students often lose marks not because of lack of knowledge, but because they misunderstand command terms. These instruction words define how answers must be structured, how deep explanations should go, and how marks are awarded by examiners.

Mastering IB Command Terms Explained allows students to convert average answers into high-scoring responses by aligning with IB marking schemes.

IB command terms include Define, Describe, Explain, Analyse, Evaluate, and Compare. Each term requires a different depth of response.

Students who clearly understand these command terms perform significantly better because they directly match examiner expectations.

Understanding command terms ensures you write exactly what examiners expect. It improves clarity, structure, and marking accuracy in every subject including IB Physics, IB Chemistry, IB Maths, and IB Biology.

Examiners follow strict marking schemes based on command terms. For example, “Define” requires exact meaning, while “Evaluate” requires balanced arguments with conclusion.

Even correct content can lose marks if the command term is not followed properly, making this skill essential for IB success.

Give a precise short definition without explanation.

Example: Photosynthesis is the process where plants convert sunlight into chemical energy.

Show reasoning, cause, and process clearly.

Example: Osmosis is movement of water through a semi-permeable membrane due to concentration differences.

Include advantages, disadvantages, and final judgment.

Example: Renewable energy is clean but expensive initially.

Show both similarities and differences clearly.

Example: Mitosis produces identical cells, meiosis produces genetic variation.

Most IB students search for command terms before exams because they struggle with structuring answers correctly even when they know the content.

This page helps solve that problem by providing real exam-based understanding and structured guidance.

• Overwriting Define answers
• Missing reasoning in Explain
• No conclusion in Evaluate
• Weak comparison structure

At Nivara Academy, we train students using structured IB answer-writing methods, examiner-style practice, and conceptual clarity sessions.

We align our teaching with the official IB Diploma Programme framework to ensure academic accuracy and exam relevance.
