Colleges identify prospective students by purchasing "student lists." Student list products are selection devices that use search filters to select students. Drawing from the sociology of race, we conceptualize some filters as "racialized inputs," defined as inputs that are correlated with race because disadvantaged racial groups have historically been excluded from the input. Using a national sample of high school students, we explore the relationship between racialized search filters and the racial composition of included versus excluded students. Using data about actual lists purchased by public universities, we investigate how college administrators utilize racialized search filters. We discuss implications for federal and state policy. We motivate policy research about structural racism embedded in selection devices that allocate students to opportunities.
