The "Lindamood Phoneme Sequencing"[R] ("LiPS"[R]) program (formerly called the "Auditory Discrimination in Depth"[R] ["ADD"] program) is designed to teach students the skills they need to decode words and to identify individual sounds and blends in words. Thirty-one studies reviewed by the What Works Clearinghouse (WWC) investigated the effects of "LiPS"[R] on students with learning disabilities. One study (Torgesen et al., 2001) is a randomized controlled trial that meets WWC evidence standards. The remaining 30 studies do not meet either WWC evidence standards or eligibility screens. Appendices include: (1) Study Characteristics: Torgesen et al., 2001 (randomized controlled trial); (2) Outcome measures; (3) Summary of study findings; (4) Summary of one-year follow-up findings; (5) "LiPS"[R] rating; and (6) Extent of evidence by domain.
