Description¶
The article introduces "a novel measure of teacher quality—called revealed comparative advantage—that estimates teachers' impact on racial achievement differences." A teacher's comparative advantage for Black students is their differential impact on Black students relative to non-Black students; a positive value means the teacher closed existing racial achievement differences, and the measure "can be interpreted as the teacher's contribution to equity." It is constructed from the same race-specific value-added calculations used in the study and can be incorporated into policy decisions.

Claims¶
- Teacher effectiveness for Black students is only imperfectly correlated with effectiveness for non-Black students (correlations between 0.28 and 0.67 depending on subject and grade level) [+M]
- Teacher impacts on Black students' test scores vary widely, from 0.2 standard deviations in middle school English to 0.5 standard deviations in elementary school math between high- and low-effectiveness teachers [+M]
- Race-specific value-added scores predict teachers' subsequent effects: Black students taught by a teacher with high prior effectiveness for Black students show gains of about one standard deviation when the teacher moves schools or grades [+M]
- Having a teacher highly effective for Black students shows no detrimental effect on non-Black students' test scores [+M]
- Experienced teachers and teachers with a master's degree are highly effective overall but much less effective for Black than non-Black students [+M]
