Big news from LA, which is the only city for which teacher value-added scores are released publicly:
The Los Angeles Times on Sunday is releasing a major update to its elementary school teacher ratings, underscoring the large disparities throughout the nation's second-largest school district in instructors' abilities to raise student test scores.
The posting — the only publication of such teacher performance data in the nation — contains value-added ratings for about 11,500 third- through fifth-grade teachers, nearly double the number released last August. It also reflects changes in the way the scores were calculated and displayed.
Overall ratings for about 470 schools also are included in the release, which is based on student standardized test scores from the academic years 2003-04 through 2009-10. To obtain the rating of a teacher or school, go to latimes.com/valueadded and enter the teacher's or the school's name.
The initial release of teacher ratings last summer generated intense controversy — and some praise — across the country, and this round has already met with some opposition.
