What information do you have on public high school graduation rates?
This Fast Fact examines the percentage of public high school students who graduate on time, as measured by the adjusted cohort graduation rate (ACGR). State education agencies calculate the ACGR by identifying the "cohort" of first-time 9th-graders in a particular school year. The cohort is then adjusted by adding any students who transfer into the cohort after 9th grade and subtracting any students who transfer out, emigrate to another country, or die. The ACGR is the percentage of students in this adjusted cohort who graduate within 4 years with a regular high school diploma. The U.S. Department of Education first collected the ACGR in 2010–11.
The ACGR increased over the first 6 years it was collected, from 79 percent in 2010–11 to 84 percent in 2015–16. In other words, more than four out of five 9th-graders in 2012–13 had completed high school within 4 years by 2015–16. In 2015–16, the state-level ACGRs ranged from 69 percent in the District of Columbia to 91 percent in Iowa.1 More than two-thirds of states (36) reported graduation rates from 80 percent to less than 90 percent.2
