High School Graduation Rates

The US Department of Education has required that all states adopt a uniform graduation rate calculation method.

OSSE has developed guidance to provide a framework for understanding the US Department of Education rules on calculating graduation rates. OSSE also published a comparison document to explain the differences between the cohort graduation rate and the previous graduation rate calculation method.
