The state auditor in Ohio found 10 schools in Columbus where thousands of students had mysteriously been removed from the school’s rolls to inflate the scores.

This is the predictable result of high-stakes testing, which has incentivized cheating, score inflation, and gaming the system. This is not the first instance where a district or a state has tried to puff up its results to meet its targets. NCLB has created an era of institutionalized fraud, not better education.

The article says:

In all, the 10 schools had no supporting documents to validate their claims that more than 300 students total had withdrawn that school year. Auditors could not locate supporting files, document the dates that students supposedly left or confirm that students transferred to other districts, were expelled, were truants, were being home-schooled or withdrew for other reasons.

In each of those 10 schools, between 20 percent and about 28 percent of students were excluded from the school’s report-card data for the 2010-11 school year.
