How is Graduation Rate calculated?

When students enter 9th grade they enter a graduation cohort, a group of students who begin as first time 9th graders in a particular school year and who graduate with a regular high school diploma in four years or less. If a student does not graduate on time (within that 4 years), the student will not count against as part of that year’s graduation rate.

Cohorts can be adjusted throughout the 4-year term. A cohort is adjusted by adding any students transferring into a cohort in a school and by subtracting any students who transfer out or are otherwise allowed to be removed from the cohort.

Students are not counted in a school’s graduation rate when exiting before the end of their four years of expected enrollment in high school grades 9-12 for any of the following reasons, but only when districts obtain the documentation required by federal regulation:

  • Transferred to a home school curriculum or another diploma granting high school
  • Moved out of the country
  • Deceased

A student who transfers into a school, is required to be assigned to the cohort in which the student started 9th grade for the first time, even if this event occurred in a different district or school.

A student not counted as graduating in four years may have:

  • Dropped out, been rumored to transfer (no written confirmation), or left for reasons unknown by the school
  • Left school to participate in a non-high school diploma granting educational or trade program (including GED)
  • Attended high school in grades 9-12 for 4 full years without graduating (may still be seeking a diploma in 5 or 6 years)
