Well-documented racial disparities in rates of exclusionary discipline may arise from differences in hard-to-observe student behavior or bias, in which treatment for the same behavior varies by student race or ethnicity. We provide evidence for the presence of bias using statewide administrative data that contain rich details on individual disciplinary infractions. Two complementary empirical strategies identify bias in suspension outcomes. The first uses within-incident variation in disciplinary outcomes across White and under-represented minority students. The second employs individual fixed effects to examine how consequences vary for students across incidents based on the race of the other student involved in the incident. Both approaches find that Black students are suspended for longer than Hispanic or White students, while there is no evidence of Hispanic-White disparities. The similarity of findings across approaches and the ability of individual fixed effect models to account for unobserved characteristics common across disciplinary incidents provide support that remaining racial disparities are likely not driven by behavior.

We study racial bias and the persistence of first impressions in the context of education. Teachers who begin their careers in classrooms with large black-white score gaps carry negative views into evaluations of future cohorts of black students. Our evidence is based on novel data on blind evaluations and non-blind public school teacher assessments of fourth and fifth graders in North Carolina. Negative first impressions lead teachers to be significantly less likely to over-rate but not more likely to under-rate black students’ math and reading skills relative to their white classmates. Teachers' perceptions are sensitive to the lowest-performing black students in early classrooms, but non-responsive to highest-performing ones. This is consistent with the operation of confirmatory biases. Since teacher expectations can shape grading patterns and sorting into academic tracks as well as students’ own beliefs and behaviors, these findings suggest that novice teacher initial experiences may contribute to the persistence of racial gaps in educational achievement and attainment.
