All that glitters is not gold

Is it scandal season or something? It now appears that many DC schools may have doctored DC CAS answer sheets. In the case of Noyes Education Campus, test scorers noted an abnormally high rate of wrong-to-right erasures. One classroom averaged 12.7 wrong-to-right erasures per student versus the district-wide average of less than 1 erasure. Here is a link to several internal DCPS documents discussing Eraser-gate. Thank goodness for FOIA.
