Proposal for Higher Level ESS from 2024
The ERM established the need for the development of a higher level course that would address the
demand from schools. The content of both the standard and higher level courses should reflect
the interdisciplinary nature of the subject. In addition, students who wish to study courses with an
environmental focus at a tertiary level education would be better prepared. (DP Environmental systems and societies Curriculum review report 2, 2021) -
