"Since its founding in 1977, EdSource has broadened its focus to include a broad range of education reforms, including charter schools, school accountability, STEM education, teacher evaluation and obstacles students face in the math pipeline from pre-kindergarten to college." Several Stanford faculty members have been involved with EdSource over the years and it was through one of them that we were able to bring in the EdSource archives which are now processed and ready for use by historians interested in education policy in California.
