Controls are father’s and mother’s education, location of school, age and gender (omitted from the table because of a non-significant Beta value). e^B = exponentiated B. For caste variable, backward caste is the reference category.

^†The type of school was coded as 1 for public school and as 0 for private school. 95% CI, 95% confidence interval; B, intercept; BC, Backward Caste; EXP (B), exponentiation of the B coefficient; FC, Forward Caste; MBC, Most Backward Caste; SC/ST, Scheduled Caste/Scheduled Tribe; SE, standard error; Wald, Wald chi-square; Sig, significance.

^*P < 0.05.
