High School Graduation Rates

  • The Delaware Department of Education (DDOE) report on graduation is from data collected annually. Delaware collects data from all public schools that include grade 12. Cohort graduation rates are calculated as prescribed by the National Center for Educational Statistics (NCES), which provides data to the federal reporting system. In accordance with NCES requirements, Delaware uses the four-year adjusted cohort graduation rate, which measures the number and percentage of cohort members who earned a regular high school diploma within four years or less. The cohort is defined as the number of first-time 9th graders followed for four years plus students who transfer in minus students who transfer out, emigrate, or are deceased during that time period. The report also provides five-year and six-year graduation rates.
