Thirteen D.C. public schools will offer extended school days next year, using part of a $10 million grant the school system is giving its campuses to boost student achievement through innovation.

Overall, 59 schools are splitting the Proving What’s Possible grant money, with most of the $10 million going to DC Public Schools’ 40 lowest-performing schools. Ward 8’s Stanton Elementary, where less than 10 percent of students can read proficiently, is using its $300,000 grant to start a small academy within the school for struggling students, among other strategies. Ward 7’s Kelly Miller Middle School is implementing not just an extended school day, but summer sessions for its students with a $490,000 grant. More than 100 schools submitted 135 applications.
