Notes: The extended model specification is presented. For brevity, we do not here present the full set of parameter estimates. Figures for WAI and PPVT models are changes in log test scores. Figures for all other models are marginal changes in the probability of being classified by the teacher as “less competent than others” or as “much less competent than others” for each variable calculated at the sample mean values. Figures in parentheses are t statistics. Sample sizes are 2,401 for females and 2,467 for males in WAI models; 2,144 for females and 2,211 for males in PPVT models; and 1,488 for females and 1,549 for males in all other models.
