35 D.C. classrooms investigated for possible cheating

Thirty-five District classrooms are being investigated for possible cheating on last spring’s standardized tests, nearly double the number of classes investigated in 2010, school officials said Thursday.

The Office of the State Superintendent for Education quietly concluded its analysis of anomalies on the 2011 D.C. Comprehensive Assessment System by recommending that nearly three dozen classrooms — less than 1 percent of the 4,279 classrooms tested — be further investigated by an independent firm that OSSE is expected to choose Monday.
