High School Graduation Rates for Class of 2013

We estimated graduation rates using 9th grade cohorts from the 2009-10 school year and a four-year graduation rate. We took the number of 9th graders who earned a regular high school diploma by 2012-13 and divided it by the number of first-time 9th graders in the starting cohort (fall 2009), plus students who transferred in and minus students who transferred out of the school between 2009 and 2013.
