12 Aug Using Older ESS Syllabus Notes: What to Check First
Course-version note: this page originally listed topics from the previous ESS syllabus. For students taking the course first assessed in 2026, use the current SL or HL guide and your school’s course outline. Do not treat older topic numbers or assessment instructions as current requirements.
Check the course before using revision notes
The current ESS course is available at SL and HL. Its central concepts include perspectives, systems and sustainability. HL adds further depth, including environmental law, environmental and ecological economics, and environmental ethics. The official IB curriculum update explains the changes.
An older explanation of an ecological process can still be useful. However, you should check which content, terminology and assessment expectations apply to your course before using it to plan revision.
Three checks for any syllabus resource
- Version: identify the first-assessment year and whether the material is for SL, HL or an earlier course.
- Purpose: distinguish a course outline from a revision summary or a practice exercise.
- Assessment: verify exam formats, weightings and IA instructions against current official information.
For example, a list of environmental disasters does not explain how each event influenced a particular environmental response. Select a relevant example and investigate the connection, rather than memorising names without context.
Connect notes to something you can do
After reading a section, try explaining a process, interpreting a graph or planning a response. Review the attempt to identify what needs clarification. Keep a short list of questions to ask your teacher.
For a current approach to revision, read planning ESS study for SL and HL. The related guides on EVS inputs and decisions and avoiding oversimplified environmental labels focus on applying ideas.
