This study examined effects of a repeated reading intervention, Quick Reads, with incidental word-level scaffolding instruction. Second- and third-grade students with passage-reading fluency performance between the 10th and 60th percentiles were randomly assigned to dyads, which were in turn randomly assigned to treatment (paired tutoring, n = 82) or control (no tutoring, n = 80) conditions. Paraeducators tutored dyads for 30 min per day, 4 days per week, for 15 weeks (November-March). At midintervention, most teachers with students in the study were formally observed during their literacy blocks. Multilevel modeling was used to test for direct treatment effects on pretest-posttest gains as well as to test for unique treatment effects after classroom oral text reading time, 2 pretests, and corresponding interactions were accounted for. Model results revealed both direct and unique treatment effects on gains in word reading and fluency. Moreover, complex interactions between group, oral text reading time, and pretests were also detected, suggesting that pretest skills should be taken into account when considering repeated reading instruction for 2nd and 3rd graders with low to average passage-reading fluency.
