The diversity of the 4,613 campuses with more than 20 Texas Teachers (external - login to view) was analyzed. Smaller campuses were excluded from the analysis to avoid the distortion that can occur when calculating percentages based on small numbers. The value of the indexes can range from zero to 100, with 100 representing the standard of diversity measured by the index. For example, 100 on the teacher diversity index represents a teaching force that is 48 percent white, 35 percent Hispanic, and 14 percent African American. A 100 on the student/teacher correspondence index represents a teaching force that matches the ethnicity of the students on the campus, whatever the ethnic makeup of the student body.
Campuses in major urban districts have the most diverse teaching staffs. Their Texas teacher diversity index score of 72 is the highest of any group. The least diverse campuses are in the rural school districts, with a teacher diversity index score of 52. The campuses in other types of communities fall within a range of 56 to 59.
