Scholars document considerable disparities in teacher perceptions of students, yet absent from this literature is an examination of how race, ethnicity, and immigration status intersect to influence teacher ratings. This study extends previous research by examining variation in teachers' ratings of academic ability across four conventional racial/ethnic groups as well as thirteen racialized subgroups. Using data from the Early Childhood Longitudinal Study-Kindergarten Class of 1998-1999, we find that black first-graders receive lower ratings in language and literacy, a pattern that holds for both black Americans and black immigrants. In contrast, Asian first-graders receive higher ratings in math; however, this is primarily driven by teachers' much higher ratings of East Asian and Southeast Asian immigrants. These subgroup differences remain even after controlling for a host of background and contextual factors, as well as students' tested ability and academic growth in math and reading. Teacher perceptions of student academic behavior explain lower language and literacy ratings for black Americans and higher math ratings for Southeast Asian immigrants that are present net background and performance, but higher math ratings for East Asian immigrants remain. We conclude by discussing implications of our approach and findings.
