High school students not graduating on time in the United States

Change Indicator

Why This Indicator Matters

Students who graduate from high school on time are more likely to continue to postsecondary education and training; they are more employable and have higher incomes than students who fail to graduate. High school graduates also have better health outcomes, make healthier choices and are less likely to engage in risky behaviors.

High school students not graduating on time

Data Provided By
Note: Non-consecutive years appear adjacent in the trend line
because one or more years have been deselected.

Definitions: The percentage of an entering freshman class not graduating in four years. The measure is derived from the Adjusted Cohort Graduation Rate (ACGR). The four-year adjusted cohort graduation rate is the number of students who graduate in four years with a regular high school diploma divided by the number of students who form the adjusted cohort for the graduating class. Students entering grade 9 for the first time form a cohort that is “adjusted” by adding any students who subsequently transfer into the cohort and subtracting any students who subsequently transfer out.
