This paper examines the relationship between teacher unionization, student achievement and teachers' pay using a cross-section of data from private schools in India. We use differences in student mark across subjects to identify within-pupil variation in achievement and find that union membership of the teacher is associated with reduced pupil achievement. We find no evidence this could be due to the unobservables not controlled for by this procedure. A school fixed effects equation of teacher pay shows that union membership raises pay and in this case too we find that remaining unobservables are unlikely to explain this outcome. We discuss the policy implications of the findings and show that the effectiveness of teacher credentials in improving teacher performance is linked to unionization.
