Why This Indicator Matters

Students who graduate from high school have higher wages, lower unemployment and are less likely to need public assistance than those who do not graduate. Their long-term physical and mental health is also better if they graduate from high school.

Definitions: The number and percent of youth who graduate in 4 years from public schools and 60% publicly funded private schools. The numerator is the number of youth graduating in the state in 4 years and the denominator includes the cohort of ninth grade students 4 years prior plus all transfers in and all transfers out.
For this calculation the denominator contains the cohort of all first time ninth graders from four years earlier plus all transfers into this cohort minus all transfers out (e.g. death, moving to another Maine school). The numerator contained only “regular” diploma recipients from the four year cohort. “Regular” diplomas include diplomas received by SWD students granted five/six years by their IEP, and Limited English Proficient (LEP) students granted five/six years as part of their documented Personal Learning Plans.
