The majority of U.S. states have adopted new teacher evaluation systems over the past 5-10 years. Although these new systems remain among the most contentious issues in education policy today, there is still only minimal evidence on their impact on student performance or other outcomes. This is largely because good research takes time.
A new article, published in the journal Education Finance and Policy, is among the handful of analyses examining the preliminary impact of teacher evaluation systems. The researchers, Matthew Steinberg and Lauren Sartain, take a look at the Excellence in Teaching Project (EITP), a pilot program carried out in Chicago Public Schools starting in the 2008-09 school year. A total of 44 elementary schools participated in EITP in the first year (cohort 1), while an additional 49 schools (cohort 2) implemented the new evaluation systems the following year (2009-10). Participating schools were randomly selected, which permits researchers to gauge the impact of the evaluations experimentally.
The results of this study are important in themselves, and they also suggest some more general points about new teacher evaluations and the building body of evidence surrounding them.
