High school graduation is a composite percentage, showing students in a four-year adjusted cohort graduating in 4, 5, or 6 years. Data is mapped based on the geographic location of the school.

Notes: (1) 2021 graduation rates are not included in the data due to reporting changes during the COVID-19 pandemic. (2) "Pursuant to federal regulations, the term four-year adjusted cohort graduation rate is the number of students who graduate within four years with a regular high school diploma divided by the number of students who form the adjusted cohort for that graduating class" (Source: OSDE). (3) According to the Oklahoma State Department of Education, "students are assigned a cohort year upon entering high school, generally four years after their initial enrollment." The adjusted cohort is created "by adding students who transfer in after 9th grade and subtracting students who emigrate, transfer to another diploma issuing school or pass away."
