Errors found in Michigan school progress reports

Tim Martin:

A new audit says Michigan’s annual school progress reports from 2004-05 and 2005-06 contained some errors that might have artificially improved some schools’ results.
The Office of the Auditor General report [1.6MB PDF] released Wednesday dealt with the Michigan Department of Education’s school report cards and adequate yearly progress reports based on federal No Child Left Behind rules.
The problem stemmed in part from inaccuracies and inconsistencies in computer programming logic used to calculate the scores. But there were other problems cited in the audit, including insufficient monitoring of data supplied by school districts — some of which may contain inflated favorable self-reporting and missing information.
