Planning IB ESS Study for SL and HL: Concepts and Skills

02 Aug Planning IB ESS Study for SL and HL: Concepts and Skills

For the IB ESS course first assessed in 2026. Environmental systems and societies is available at standard level (SL) and higher level (HL). An ESS study plan needs to match the student’s level, assessment session and current school course. The previous description on this page used an older course structure and should not be used to plan current exam preparation.

How SL and HL preparation differs

Both levels connect environmental science with the ways societies understand and respond to environmental issues. HL includes additional depth and breadth, with specific lenses involving environmental law, environmental and ecological economics, and environmental ethics. The IB curriculum update outlines these changes.

Start by checking the current guide and your teacher’s course outline. A revision resource from an earlier syllabus can still explain a relevant concept, but its topic labels, assessment details or teaching-hour breakdown may no longer apply.

Build a study plan from skills as well as topics

A useful plan identifies what the student needs to do with the content. For each area studied at school, ask:

• Can I explain the process in my own words?
• Can I interpret relevant data, including units and uncertainty?
• Can I link an environmental change to its consequences for people or ecosystems?
• Can I compare perspectives and support a judgment with evidence?

For example, knowing a definition of sustainability is different from evaluating a management decision. A practice answer should connect the proposed action, its environmental effects, the people affected and any important limitations.

Use the appropriate type of practice

Short questions can help reveal gaps in definitions, calculations or cause-and-effect explanations. Data questions require careful reading of the information provided. Longer responses need a focused argument and evidence relevant to the question.

Use practice materials that match your course and assessment session. Review a completed answer before doing more questions: identify whether the difficulty was knowledge, selecting evidence, interpreting the command term or explaining the reasoning. Our focused ESS revision plan gives a practical routine for this process.

Develop independent investigation skills

IA preparation involves learning how to frame a research question, select a method, analyse evidence and evaluate limitations. Students should understand why their choices are suitable for their investigation. A tutor can explain these skills and help a student practise them while the student produces their own work in line with school and IB requirements.

See our ESS IA structure guide for a starting point.

Discuss the student’s next learning goal

Marija Maletz is an ESS teacher, examiner and tutor. Before discussing support, prepare the student’s SL or HL level, assessment session, recent topics and one example of a task they find difficult. This makes it easier to identify a useful focus.
