Many education policymakers and system leaders prioritize recruiting and developing effective school leaders as key mechanisms to improve school climate and student learning. Despite efforts to select and support successful school leaders, however, relatively little is understood about the prior professional experiences and skillsets that principals possess upon entry into their positions. In this descriptive paper, we use 14 years of administrative data on all educators in Oregon to trace the prior professional experiences and instructional effectiveness of those who become school leaders. We highlight that many principals in Oregon acquire educational leadership experience outside the assistant principal role and outside of the school district in which they serve as principals. We also find that when future school leaders were teachers, they improved student achievement at modestly higher rates than their peers. Insight into these topics has the potential to inform the pre-service training, recruitment and professional development of school leaders.

Federal law defines eligibility for English learner (EL) classification differently for Indigenous students compared to non-Indigenous students. Indigenous students, unlike non-Indigenous students, are not required to have a non-English home or primary language. A critical question, therefore, is how EL classification impacts Indigenous students’ educational outcomes. This study explores this question for Alaska Native students, drawing on data from five Alaska school districts. Using a regression discontinuity design, we find evidence that among students who score near the EL classification threshold in kindergarten, EL classification has a large negative impact on Alaska Native students’ academic outcomes, especially in the 3rd and 4th grades. Negative impacts are not found for non-Alaska Native students in the same districts.

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.
