What does this measure?
The number of students graduating after four years of high school, expressed as a percentage of their cohort. A cohort is a class of ninth-graders beginning high school in the same academic year.
Why is this important?
High school graduation is the culmination of a successful K-12 education and the gateway to college or employment. Students who do not graduate face the prospect of unemployment or low-paying jobs.
