The percentage of the students expected to graduate in four years who actually did graduate. Graduation rate is calculated by dividing the number of students in the 4-year adjusted cohort who graduate in four years or less with either a traditional high school diploma, an adult education high school diploma, or have passed the California High School Proficiency Exam (CHSPE) by the number of students who form the adjusted cohort for that graduating class. California began using cohort data to report graduation rates with the 2009-10 school year.
