The Los Angeles Unified School District will ask labor unions to adopt a new approach to teacher evaluations that would judge instructors partly by their ability to raise students’ test scores — a sudden and fundamental change in how the nation’s second-largest district assesses its educators.
The teachers union has for years staunchly resisted using student test data in instructors’ reviews.
The district’s actions come in response to a Times article on teacher effectiveness. The article was based on an analysis, called “value-added,” which measures teachers by analyzing their students’ performance on standardized tests. The approach has been embraced by education reformers as a way to bring objectivity to teacher evaluations.
