What is "on time" for graduation?

For high school, on time means 4 years from first entering 9th grade. Extended rates (5 or 6 year) may also be reported.

How does the U.S. national average compare?

The national high school graduation rate is approximately 87%. College six-year graduation rates average around 63%.

GED recipients are not counted in the standard cohort graduation rate but may be reported separately.

Calculate the cohort graduation rate by tracking how many students from a starting class graduate on time.

Graduation Rate vs Graduated On Time

The adjusted cohort graduation rate (ACGR) is the federal standard for measuring on-time graduation.

Adjusted Cohort = Starting Cohort + Transfers In - Transfers Out

Graduation Rate = On-Time Graduates / Adjusted Cohort x 100

This method accounts for student mobility and provides a fairer comparison across schools than simple counts.

A cohort starts with 250 freshmen, 15 transfer in, 20 transfer out, and 210 graduate on time.
