High School Three Course Model

The High School Three Course Model contains The Living Earth, Chemistry in the Earth System, and Physics in the Universe courses. The three course model combines all high school performance expectations (PEs) into three courses.  To highlight the nature of Earth and space sciences (ESS) as an interdisciplinary pursuit with crucial importance in California, the three courses present an integration of ESS and one of the other high school disciplines.
