Note. Estimates standardized. T1, T5 = intercept set at times 1 and 5. Bolded estimates are cases in which slope is a significant predictor. No model was estimated for Novel students because there was no significant variance in ORF-PF slope among these students (see Table 2b). CFI = .97/.97, RMSEA = .12/.13, SRMR = .04/.04 for Passage Comprehension and Sight Word Oral Reading Fluency, respectively.
