"SpellRead"[TM], formerly known as "SpellRead Phonological Auditory Training"[R], is a small-group literacy program for struggling readers in grades 2-12. "SpellRead"[TM] integrates the auditory and visual aspects of the reading process and emphasizes specific skill mastery through systematic and explicit instruction. Students are taught to recognize and manipulate English sounds; to practice, apply, and transfer their skills using texts at their reading level; and to write about their reading. The What Works Clearinghouse (WWC) identified 14 studies on the effects of "SpellRead"[TM] on the reading achievement of adolescent readers. Two studies (Rashotte, MacPhee, & Torgesen, 2001; Torgesen et al., 2006) are randomized controlled trials that meet WWC evidence standards without reservations. These two studies are summarized in this report. The remaining 12 studies do not meet either WWC eligibility screens or evidence standards. Appended are: (1) Research details for Rashotte, MacPhee, & Torgesen, 2001 and Torgesen et al. (2006); (2) Outcome measures for each domain; (3) Findings included in the rating for the alphabetics domain, reading fluency domain, and comprehension domain; and (4) Supplemental findings for the alphabetics domain, reading fluency domain, and comprehension domain. A glossary of terms is included. (Contains 7 tables, 9 endnotes and 1 additional source.)
