The Washington, D.C., Charter Board has voted to shutter Potomac Preparatory Charter School, determining that it has fallen short of necessary performance targets.
The Washington Post reports that the school will close at the end of the academic year, and its more than 400 students will need to find new schools.
Potomac Prep, which used to be called Potomac Lighthouse, nearly lost its charter in 2014 because of poor performance. But the school was given conditional approval to stay open under new management and a turnaround plan.
But the board concluded that the school fell short of meeting its targets in 2014-2015.
In its decision letter about the closure, the board wrote that it "has a great deal of respect for the work done by the teachers, students, families, and administrators at Potomac Prep over the last two years."
"However, this cultural improvement has not translated into measurable academic improvements, and this board is charged with revoking the charters of schools when it finds, in its expert opinion, that a school fails to meet its goals and academic achievement expectations," the decision stated.
