Historically, teacher evaluation systems have identified few teachers as low-performing and needing improvement. In 2012, at the beginning of a national reform movement, Chicago Public Schools implemented its overhauled evaluation system, which incorporated multiple measures of teaching practice and dismissal plans for low-rated teachers. We find that the reform increased the exit rate of low-rated tenured teachers by 50 percent. At the same time, the teachers who replaced the exited teachers were significantly higher-performing. Ultimately, the accountability function of the reformed teacher evaluation policy resulted in higher teaching quality. However, the policy impact was limited because very few teachers received low ratings under the reformed system. Policy simulation results suggest that the available teacher labor supply is likely sufficient to set a higher standard for satisfactory teaching.

In 2017, Chicago Public Schools adopted an online universal application system for all high schools with the hope of providing more equitable access to high-performance schools. Despite the new system, black students and students living in low socioeconomic status (SES) neighborhoods remained less likely than their peers to enroll in a high-performance high school. In this paper, we characterize various constraints that students and families may face in enrolling in a high-performance high school, including eligibility to programs based on prior academic achievement, distance from high-performance options, elementary school performance ratings, and neighborhood SES. After adjusting for differences in these access factors, we find the gap between black and Latinx students’ likelihood of enrolling in a high-performing high school is reduced by about 80 percent. We find a similarly large reduction in the enrollment gap between students from low and middle SES neighborhoods after adjusting for eligibility and distance factors. These findings have implications for policies that may help equalize access to high-performance schools through changes to eligibility requirements and improved transportation options.

Chicago Public Schools initiated the Excellence in Teaching Project, a teacher evaluation program designed to increase student learning by improving classroom instruction through structured principal–teacher dialogue. The pilot began in forty-four elementary schools in 2008–09 (cohort 1) and scaled up to include an additional forty-eight elementary schools in 2009–10 (cohort 2). Leveraging the experimental design of the rollout, cohort 1 schools performed better in reading and math than cohort 2 schools at the end of the first year, though the math effects are not statistically significant. We find the initial improvement for cohort 1 schools remains even after cohort 2 schools adopted the program. Moreover, the pilot differentially impacted schools with different characteristics. Higher-achieving and lower-poverty schools were the primary beneficiaries, suggesting the intervention was most successful in more advantaged schools. These findings are relevant for policy makers and school leaders who are implementing evaluation systems that incorporate classroom observations.
