High School Graduation Rate

Time Range: 2003-07       Resolution: Schools - Averaged to District

The high school graduation rate calculates the regular diploma recipients as a percent of students leaving high school over a four-year period (estimated as the sum of diploma recipients and dropouts during the past four years in grades 9 through 12 respectively).


The high school graduation rate is an indicator of achievement in education and of basic skills. Completion of high school is highly correlated to health outcomes. Low high school graduation rates indicate that more individuals are more likely to live shorter lives and in poverty, be unemployed, and make unhealthy decisions that may lead to addiction, incarceration, and violence1.
