A top D.C. charter school educates few at-risk students. Should it be opening a second campus?

In the District, about 46 percent of students are considered at-risk, which means they are homeless or in foster care, their families qualify for public assistance, or they have been held back more than a year in high school.

At Washington Latin, just 7 percent of middle school students are considered at-risk, and 16 percent of high school students meet the definition.
