Abstract: This dissertation examines the causal effects of the publication of individual teacher ratings on (1) teacher movement and (2) teacher-student assignment patterns in the Los Angeles Unified School District (LAUSD). Both analyses use a difference-in-differences strategy that exploits the fact that the Los Angeles Times publication of individual teacher ratings in August 2010 was an exogenous shock to the school system. In the first section, I find that elementary teachers rated average, less effective and least effective in publication were over 30 percent more likely to leave teaching in the district as a result of the publication than elementary teachers without ratings. In contrast, the leave rates of teachers rated effective were not impacted. Findings were robust to a second publication of teacher ratings at the end of the same school year. While teacher transfer rates were not impacted by the initial publication of teacher ratings, they were impacted by the second release of ratings after controlling for the earlier ratings teachers received. On average, teachers with an effective rating in the second release transferred to schools with fewer free- or reduced-price lunch (FRPL), limited English proficient (LEP) and non-white students in 2011-12 on average relative to the schools they came from as a result of the publication. Teachers rated ineffective transferred to schools with relatively more FRPL, LEP and non-white students on average.
