Note. GORT = Gray Oral Reading Test - 3^rd Edition. ORQ = Oral Reading Quotient (Standard Score). Only f values with p < 1.0 are reported. BL = Baseline scores. WIST = PHAST Intervention. RAVEO = PHAB/RAVE-O Intervention. PHAB = CSS/PHAB Intervention. MATH = CSS/MATH Intervention. Group = teaching group.
