Abstract
This policy brief provides an overview of the vision and organization of the Next Generation Science Standards (NGSS), and reviews three high school curriculum imple-mentation models developed for the California Science Framework. The brief aims to promote social justice in science education, and addresses the need for reforming curriculum, policy, and practices to improve the equitable preparedness of students for college and career. Recom-mendations for policy improvements to high school sci-ence course requirements will also be presented.
