Colorado's graduation rate failed to improve for the first time after at least four continuous years of growth, according to the most recent data released by the state on Thursday.
Statewide public schools graduated 77.3 percent of students in the spring of 2015. The rate was the same for the class of 2014.
Among metro area districts, the most growth was in the Sheridan School District just southwest of Denver. This year, the Sheridan School District graduated 75.9 percent of their students, up 16 percentage points from last year's graduation rate.
The highest district graduation rate in the metro area was the Boulder Valley School District's 92.3 percent graduation rate, followed by Douglas County School District's 90 percent graduation rate.
Denver Public Schools had a graduation rate of 64.8 percent.
A few school districts including those in Littleton, Brighton and Englewood, saw drops in their graduation rate from last year's numbers.
