"Forty-five of Washington's 150 public schools had at least one classroom with an elevated erasure level in 2008, according to the analysis, disclosed by District officials this month. A closer examination of the data shows that suspicious erasures were most heavily concentrated in third-, fourth-, fifth- and sixth-grade classrooms at a half-dozen schools: Aiton Elementary (seven classrooms); Marie Reed Elementary (six); Takoma Education Campus (five); Langdon Education Campus (four); J.O. Wilson Elementary (four); and Bowen. Five of the schools made gains that exceeded citywide averages. Langdon's scores held relatively steady."
