See how each D.C. charter school fared under new rating system

The D.C. Public Charter School Board released its annual quality ratings Friday.

More than 12,000 students — nearly a third of the city’s charter school students — are enrolled in charters that ranked in the highest of three performance tiers, an increase of 9 percent over last year.

The rating system — known as the Performance Management Framework — has been in place since 2011. It gives parents and the charter board a way to evaluate performance and compare quality of the city’s charter school campuses.  This year, 22 schools were classified as “Tier 1,” 37 were classified as “Tier 2” and 5 were classified as “Tier 3.” New schools are not classified by tier, nor are schools serving adults or preschool-aged children — though that will change in the future.

Here is a look at how schools have fared over each of the past four years. The following charts were produced by the D.C. Public Charter School Board.
