IB Environmental Systems and Societies

Transdisciplinary study linking environmental science with societal values, systems, and sustainability.

IB Environmental Systems and Societies (ESS) is a transdisciplinary course that bridges Group 3 (Individuals and Societies) and Group 4 (Sciences). Students explore environmental systems, biodiversity, pollution, resource use, and climate change while evaluating the political, economic, and ethical dimensions of environmental issues using a systems-based approach. The current course was first assessed in 2026.

How do you start?

Request a free consultation: it is a conversation about your goals and timeline, not a lesson or a test. There is no separate diagnostic test for IB Diploma, because no single test stands in for a school syllabus. The first lesson does the assessment: your tutor works through your recent marked work and past-paper questions from your own specification, and reads where you stand. It is a normal paid lesson, not a free trial, and it teaches as it assesses.
