Notes: ^†Values for the dependent variable increase with better self-reported school performance: from Low, Mid-low, Middle, Mid-high to High. Coefficients are shown. **, *. Panel D full model results are estimates from Table 2. Covariates include father’s and mother’s education, household economic status, number of cars at home, having no bedroom for the student, number of computers at home, residence area type, school level, and survey year.
