Indiana Department of Education Graduation Rate
Summary
An accurate measure of the high school graduation rate is a critical step toward improving our understanding of students who do not earn regular high school diplomas or who take longer than four years to graduate. IC 20-26-13 outlines the formula for determining high school graduation rates. The formula establishes a cohort (or expected graduation year) of first-time freshmen that expands and contracts as students transfer in and out of school during the years that follow. Since a student never moves to a different cohort, we have an accurate measure of the percentage of students who graduate in four years or less. By publishing five and six year rates, we account for those students who persist even though they do not graduate in the standard number of years.
