Note. TBRS = Teacher Behavior Rating Scale. TBRS Literacy variables are composites of oral language, book reading, written expression, and print and letter knowledge. Further detail on classroom observational measures is available in Appendix Tables 1a & b. p-values account for clustering by random assignment site and date of classroom observational assessment (for classroom observation t-tests only). Ns are rounded to the nearest 10 in accordance with NCES data policies.
