Supplemental Educational Services (SES) are tutoring or other supplemental academic enrichment activities beyond the regular school day. The law requires SES to be of high quality, research-based, and designed to improve the academic achievement of participating students. Students are eligible for these services if they are enrolled in any of the state's 5,080 Title I schools, not meeting State Board of Education content standards in reading and math, and from low-income families.

The option of school choice must be made available to all students the second year a school is identified for school improvement and all subsequent years thereafter, until the school has made adequate yearly progress for two consecutive years.

A Provider offering Supplemental Educational Services must be state-approved. A list of schools that qualify for SES will be available in August after the CST results have been posted by CDE.
