ESS Essay Structure: Planning, Evidence and Evaluation

16 Sep ESS Essay Structure: Planning, Evidence and Evaluation

ESS essay structure should follow the question, its command term and the marks available. A clear argument, accurate environmental knowledge and relevant evidence work together. No fixed paragraph count, linking word or template guarantees a mark.

1. Read the question before choosing a structure

Underline the command term and identify the scope: the strategy, system, location or issue you must address. A describe response differs from an evaluate response. Check your current course materials and the markscheme for the particular practice question.

2. Make a short plan

List the main points needed to answer the question and select relevant evidence. For an evaluative question, consider strengths, limitations, perspectives and the conditions under which a strategy works. Allocate time in proportion to marks, allowing for the rest of the paper and a final check.

3. Build paragraphs around reasoning

A useful planning aid is point, evidence and explanation. State a relevant point, support it with accurate information and explain how it addresses the question. Add evaluation where the task requires it. The sequence is flexible; avoid forcing every paragraph into identical sentences.

For example, an evaluation of protected areas might consider habitat protection alongside enforcement, funding and species movement across boundaries. Use a documented case rather than inventing a population trend or assuming that every protected area succeeds.

4. Use case studies precisely

Choose examples you understand well enough to explain. Name the relevant location, policy or process and use reliable figures when you know them. Distinguish a policy’s intended effect from evidence of its actual outcome. A named case alone does not establish causation.

Words such as “however” can introduce a limitation, but the reasoning after the word matters. Explain why the limitation affects your judgement rather than adding a generic counterpoint.

5. Answer the question in your conclusion

For an evaluative response, give a supported judgement that reflects the evidence and its limits. Do not introduce an unrelated case study at the end. A conclusion should resolve the question rather than merely repeat the introduction.

A short paragraph-revision exercise

Take one paragraph from your own practice answer. Underline the claim, circle the evidence and mark the sentence that explains its relevance. If one part is missing, revise that part before adding more words. For an evaluative question, identify where you explain a limitation or condition affecting your judgement.

A final check

• Have I answered the actual command term?
• Is each main point relevant and supported?
• Are definitions, units and case details accurate?
• Have I explained mechanisms or evaluated evidence where requested?
• Does the conclusion follow from the argument?

During revision, make a reverse outline: write the main point of each paragraph in a separate list. Look for repetition, gaps and points that drift away from the question. This is a practice technique, not an IB marking rule.
