A New Tool Can Help Districts Make Progress on Teacher Diversity

Mid-Atlantic | April 05, 2021

A recent Education Week article underscored how the COVID-19 pandemic has exacerbated the longstanding need to improve the diversity of the teacher workforce.

Expanding the diversity of teachers is one route to improving the educational outcomes of students of color and reducing disparities in achievement. Studies have documented that students, especially Black students, taught by a teacher of the same race generally score higher on math and reading tests and have better educational outcomes:

  • Black students in kindergarten to grade 3 taught by a Black teacher had math scores 2 to 5 percentile points and reading scores 3 to 6 percentile points higher than Black students in those grades taught by a White teacher (Dee, 2004).
  • Black students who have at least one Black teacher are about 5 percentage points more likely to graduate high school and about 4 percentage points more likely to enroll in college than their peers who are not assigned to a Black teacher (Gershenson et al., 2018).
  • Being taught by a teacher of the same race or ethnicity lowers suspension and expulsion rates (Holt and Gershenson, 2015, Lindsay & Hart, 2017). In particular, non-White kindergarten to grade 5 students taught by teachers of the same race/ethnicity had 19 percent fewer suspensions per year (Holt and Gershenson, 2015).

Nationwide, most students of color are not taught by teachers of their race/ethnicity. The proportion of students who are Black or Hispanic is two to three times larger than the proportion of teachers who are Black or Hispanic, and that the gap appears to be increasing (Hansen & Quintero, 2019). During the next decade, the proportion of White students will continue to decline, the proportion of Black students will stay about the same, and the proportion of Hispanic students will increase. Yet data from 2000 to 2016 suggest that teacher demographics are changing more slowly, with substantial room for improvement in diversifying the workforce.

REL Mid-Atlantic has created an automated tool to help state education agency staff support their districts in identifying gaps in the diversity of their teacher workforces. REL Mid-Atlantic's Automated Teacher Diversity District Tool generates reports showing the racial and ethnic makeup of each district's student and teacher populations and their teacher retention rates by race/ethnicity. Figures 1 and 2 show examples of the figures contained in the reports. The automated tool can also generate retention rates specifically for teachers with effective evaluation ratings, who may have more ability to improve student outcomes and may be especially important for districts to retain.

Users need only plug in the required data1 and the tool will automatically generate a report for each district of interest. The time involved depends on the availability of the data but can range from as little as 30 minutes to more than an hour. Generating the profiles takes about one to two minutes for every five districts. States may find the Automated Teacher Diversity District Tool a useful resource for better understanding the racial/ethnic makeup of their students and teachers and making progress on the path to greater teacher diversity.
