Four-Year Cohort Graduation Rate
What does this measure?
The number of students graduating after four years of high school (measured through August of the graduation year), as a percentage of their cohort. The cohort is the class of ninth-graders beginning high school in the same academic year.
Why is this important?
High school graduation is the culmination of a successful K-12 education and the gateway to college or employment. Students who do not graduate face the prospect of unemployment or low-paying jobs.
How is our region performing?
About 84% of the 2010 cohort graduated by August, 2014 in our region, compared to 79% statewide and 85% for NYS excluding New York City. The graduation rate was highest in Wyoming County (89%) and Genesee, Livingston, and Ontario Counties (all 88%). At 51%, the Rochester School District had the lowest graduation rate in the region, but it was up 3 percentage points from the previous year. The regional rate increased 3 percentage points from 2008 while the state rate, with NYC excluded, went up 6 points. Seneca County’s rate went up 10 points over the period, the largest increase in the region.
Notes about the data
Prior years are not comparable, thus are not reported. Students are included in the State total cohort based on the year they entered Grade 9 or, if ungraded, the school year in which they reached their seventeenth birthday. Students are included in the cohort of the school where they were last enrolled if they were enrolled for a minimum of five months. Students were counted as graduates if they earned a local or a Regents diploma. These figures includes students who graduate in August after making up courses during the summer. Data for this indicator are expected to be released in the second quarter.
