"Voyager Passport"[TM] is a supplemental reading intervention system for students in grades K-5. "Voyager Passport Reading Journeys"[TM] is a reading intervention program designed for adolescents who struggle with reading. The "Voyager Universal Literacy System"[R] is a K-3 reading program that includes a core reading curriculum; a progress monitoring system that measures each student's reading progress and identifies struggling readers; a struggling reader intervention that includes additional instruction time and summer school; professional development for teachers, principals, and specialists; a home study curriculum; and computer-based practice and reinforcement in phonological skills, comprehension, fluency, language development, and writing. No studies of the "Voyager" reading programs ("Voyager Passport"[TM], "Voyager Passport Reading Journeys"[TM], and "Voyager Universal Literacy System"[R]) that fall within the scope of the Students with Learning Disabilities review protocol meet What Works Clearinghouse (WWC) evidence standards. The lack of studies meeting WWC evidence standards means that, at this time, the WWC is unable to draw any conclusions based on research about the effectiveness or ineffectiveness of "Voyager" reading programs on students with learning disabilities.
