| Field Paper Abstract | Before | After We investigate the impact of ethnicity and gender on teacher assessments through a randomized controlled experiment involving 203 teachers grading a single class's assignments. Within teachers we randomly assigned names, signaling gender and ethnicity, with a control group grading anonymized assignments. We find no statistically significant evidence of grading bias based on student name, ethnicity or gender, unlike previous studies. This holds even among teachers with stronger implicit biases against foreign or male names. However, we observe significant variation in grades assigned by teachers for identical assignments. Finally, through counterfactual policy simulations, we demonstrate an economically relevant trade-off between precision and accuracy for grading policies in schools. |
