Abstract

For the second time, the Los Angeles Times has published results of statistical testing examining the variation in teacher and school performance in the Los Angeles Unified School District. Though this year's Teacher Ratings enable the reader to take into account variability and model sensitivity issues, an improvement over the 2010 report, the resulting ranking system was found to be inaccurate due to unreliable methodology.
