Principal Effects on Teacher Working Conditions 
Ataur Rahaman & Cory Koedel 
CALDER Working Paper No. 335-0226 
February 2026 

Abstract: Research on school principals highlights their role in shaping teachers’ work environments, but most evidence is qualitative or correlational. We provide plausibly causal estimates of how principals affect a broad swath of teacher working conditions using data from Illinois, where the State Board of Education collects detailed and comprehensive information annually on teacher working conditions in nearly all schools. We estimate the variance of principal effects by comparing correlations in working conditions over time in schools that do and do not experience principal changes. Under reasonable stationarity assumptions, the difference in the correlations can be used to back out the variance of principal effects. Unsurprisingly, we find principals have large effects on working conditions related to leadership directly. They also influence teachers’ professional work environments and their interactions with students and families, though their effects on these broader indicators are much smaller, particularly the latter.
