Related Claims¶

• The four Power4Kids interventions delivered about 100 hours of pull-out instruction in small groups of three students over one school year — related
• The Power4Kids evaluation used two-level random assignment: 50 schools to four interventions and struggling readers within schools to treatment or control — related
• The Power4Kids evaluation covered four widely used reading programs for elementary students with reading problems: Corrective Reading, Failure Free Reading, Spell Read P.A.T., and Wilson Reading — related
• Failure Free Reading, the only word-level-plus-comprehension program, showed impacts for third graders but no impacts for fifth graders — a narrower finding that bears on this claim
• Four remedial reading interventions combined improved phonemic decoding, word reading accuracy and fluency, and reading comprehension for third-grade struggling readers one year after the interventions ended, though not on all measures — related
