Graduation rates in Thurston County public schools vary considerably based on the year and whether or not the school is a traditional or non-traditional/alternative school. Traditional schools tend to have graduation rates that are significantly higher than state and countywide averages, while non-traditional schools tend to have lower graduation rates.
In Thurston County, the school with the highest graduation rates for the 2015-2016 school year was Capital High School, which had over 91% of its students graduate.
Between 2011 and 2015, the countywide graduation has decreased from 80% to just under 75%, despite increases in the statewide graduation rate.
OSPI calculates graduation rates using the “adjusted 4-year cohort rate” methodology. Students are placed in a group — or cohort — based on the year they enter ninth grade for the first time. The calculation adjusts for students who transfer into a Washington public high school for the first time and join a cohort. Students are removed from the cohort if they transfer out of public school in Washington.
The adjusted cohort method tracks individual students over time and does not rely on estimates. It generally aligns with what most people think of as a graduation rate: Among a group of students who started high school together, what percent graduated in four years?
