DC Prep operates four charter schools here with 1,200 students in preschool through eighth grade. The schools, whose students are mostly poor and black, are among the highest performing in Washington. Last year, DC Prep’s flagship middle school earned the best test scores among local charter schools, far outperforming the average of the city’s traditional neighborhood schools as well.
Another, less trumpeted, distinction for DC Prep is the extent to which it — as well as many other charter schools in the city — relies on the Walton Family Foundation, a philanthropic group governed by the family that founded Walmart.
Since 2002, the charter network has received close to $1.2 million from Walton in direct grants. A Walton-funded nonprofit helped DC Prep find building space when it moved its first two schools from a chapel basement into former warehouses that now have large classrooms and wide, art-filled hallways.
