D.C. Discloses Mistakes in 'Value Added' Scores
Errors were made in calculating the "value added" scores of 10 percent of the District of Columbia teachers who were evaluated using that model for the 2012-13 school year.
In total, 22 teachers received a lower rating than they should have, and 22 received a higher rating, according to the school district. Although the district employs about 4,000 teachers, only 440 were evaluated on a model that counts student test scores as a significant factor.
As a result of those miscalculations made by Mathematica Policy Research, one teacher was fired. District officials say they are attempting to reinstate that teacher.
