Under the guidelines of state law, RCW 28A.175.010, the Office of Superintendent of Public Instruction (OSPI) is required to report annually on the educational progress of public school students in grades 7-12. At the direction of the U.S. Department of Education, Washington uses the adjusted cohort graduation calculation to track a single cohort of students over four or five years. This report summarizes the graduation rates following the 2015-16 school year. The adjusted cohort method yields a 79.1 percent 4-year graduation rate for the Class of 2016, students who first began 9th grade in 2012-13. This is slightly higher than the Class of 2015, whose 4-year graduation rate was 78.1 percent. An additional 3.8 percent of students in the Class of 2015 graduated during their fifth-year of high school (2015-16) for a total 5-year rate of 81.9 percent. The cumulative dropout rate, after four years, for students entering 9th grade in 2012-13 was 11.7 percent.
