Teacher evaluation policies seek to improve student outcomes by increasing the effort and skill levels of current and future teachers. Current policy and most prior research treats teacher evaluation as balancing two aims: accountability and growth. Proper teacher evaluation design has been understood as successfully weighting the accountability and growth dimensions of policy and practice. I detail six assumptions underlying teacher evaluation for growth and accountability and assess their reasonableness in light of empirical evidence from the personnel economics, social psychology and management literatures. I simulate a set of teacher evaluation policies and find that those that treat evaluation for accountability and evaluation for growth as substitutes modestly outperform policies that treat them as complements. The teachers’ rates of learning through evaluation and the labor market effects of evaluation are critical in determining its impact. I conclude with recommendations for the design of teacher evaluation policies.

Despite frequent political and policy debates, the effects of imposing accountability pressures on public school teachers are empirically indeterminate. In this paper, we study the effects of accountability in the context of teacher responses to student behavioral infractions in the aftermath of teacher evaluation reforms. We leverage cross-state variation in the timing of state policy implementation to estimate whether teachers change the rate at which they remove students from their classrooms. We find that higher-stakes teacher evaluation had no causal effect on the rates of disciplinary referrals, and we find no evidence of heterogeneous effects for grades subject to greater accountability pressures or in schools facing differing levels of disciplinary infractions. Our results are precisely estimated and robust to a battery of specification checks. Our findings provide insights on the effects of accountability policy on the black-box of classroom practice and highlight the loose-coupling of education policy and teacher behaviors.
