This article aimed to examine both preservice teachers’ and teacher educators’ attitudes toward student diversity. Two array groups emerged: Students Are Students and Diversity Advocates. The authors find gaps in attitudes toward student diversity between the two array groups. These gaps indicate both consensual and divided attitudes toward student diversity.However, a major gap in attitudes toward student diversity between the two groups is similarity versus diversity: while one group highlights similarity among students, the other group appeals for the importance of acknowledging and addressing student diversity.
