To improve the progression of students through the educational system and to improve education quality, California needs a robust data system that can track an individual student?s progress from kindergarten to college and beyond. Such a data system, commonly called a student unit record (SUR), would contain an individual electronic record of every student enrolled in an educational institution. Currently, 18 states can track individual students from kindergarten through postsecondary education, but California is not one of them. The authors of this report document the state of the various student data systems available for California?s four education segments?K?12 public schools, the community colleges, California State University, and the University of California. They also assess the feasibility of and challenges to developing a SUR data system in the state. Finally, they identify steps that could be taken toward building and maintaining an integrated SUR system for California.
