Developed to support the implementation of the California Next Generation Science Standards (CA NGSS), the CA NGSS Collaborative was formed in 2015. The CA NGSS Collaborative is a joint effort of the California Department of Education, California Science Project, California Association of Science Educators, California County Superintendents, and the K-12 Alliance. Together the Collaborative develops and delivers the statewide NGSS Rollouts and Professional Learning Experiences. In 2018, the Collaborative developed and released the California NGSS Toolkit for Instructional Material Evaluation (CA NGSS TIME).
