  1. Note. Statistics presented for demographic variables of (i) intelligence as measured by the WASI-II via Full-Scale IQ (FSIQ), Verbal Comprehension Index (VCI), and Perceptual Reasoning Index (PRI); and (ii) attention as measured by the CPT-3 d’ t score. Baseline performance on the academic outcomes was measured by the WIAT-III via Word Reading (WR), Reading Comprehension (RC), Fluency-Additions (FA), and Fluency-Subtractions (FS)
