Graduation Cohort / Dropout Rates


Cohort Graduation Rate

A cohort graduation rate follows the students who are first-time high school students in a particular year and determines the percentage that graduate within a given time frame, such as four years. An extended rate, allowing one additional year for completion, is also tracked and reported as the 5-year Cohort Graduation Rates. For more information, please contact Jon Wiens.


Dropout Rates in Oregon High Schools

Dropout data is collected in the Annual Cumulative Average Daily Membership (ADM) Data Collection each year at the end of the school year, which identifies students' enrollment dates and status as of the last day of enrollment for the year.
