LAUSD board endorses controversial system to measure teacher performance

LOS ANGELES (AP) — The Los Angeles Unified School District board has endorsed using the controversial system of using student scores on standardized tests as a way to measure teacher performance.

The board on Thursday authorized district Superintendent Ramon Cortines to start negotiating with unions to develop a new system to evaluate teachers and administrators that includes using so-called value-added data.

Value-added data examines students' standardized test scores from year to year and calculates a best-to-worst teacher ranking. It is used by districts across the nation despite union opposition.

The board's resolution stated that value-added data will only be one component of a new teacher evaluation process.

Cortines says talks with unions begin next week.
