Some studies suggest that tracking can influence students' peer groups and attitudes regarding other students. Gamoran's study (1992) shows that students are more likely to form friendships with other students in the same tracks than students outside of their tracks. Since low-class and minority students are overrepresented in low tracks with Whites and Asians generally dominating high tracks, interaction among these groups can be discouraged by tracking. However, there is no research showing an academic benefit to low track students from such interaction.
