Definition/Methodology: The four-year Graduation Rate (four-year adjusted cohort graduation rate) is defined as the number of students who graduate in four years with a regular high school diploma. From the beginning of 9th grade, students who enter that grade for the first time form a cohort that is subsequently “adjusted” through the addition and subtraction of any students who transfer into or out of the cohort during the 9th grade year and the following three years. The calculation uses individual student-level data from the state's Public School Information System (PSIS) submitted by school districts and certified by Superintendents.
Terms to know:
"Still Enrolled": Students were still in school after four years.
"Other": Includes students who dropped out (including those who enrolled in a GED program), transferred to post-secondary education or have an unknown status.
