WWC Summary of Evidence for this Intervention
Lindamood Phoneme Sequencing® (LiPS®)
The Lindamood Phoneme Sequencing® (LiPS®) program (formerly called the Auditory Discrimination in Depth® [ADD] program) is designed to teach students the skills they need to decode words and to identify individual sounds and blends in words. LiPS® is designed for emergent readers in kindergarten through grade 3 or for struggling, dyslexic readers. The program is individualized to meet students’ needs and is often used with students who have learning disabilities or difficulties. Initial activities engage students in discovering the lip, tongue, and mouth actions needed to produce specific sounds. After students are able to produce, label, and organize the sounds with their mouths, subsequent activities in sequencing, reading, and spelling use the oral aspects of sounds to identify and order them within words. The program also offers direct instruction in letter patterns, sight words, and context clues in reading.

The indicator represents the highest level of similarity found between your students and each of the high-quality studies of the intervention. Three filled in ovals indicates that at least one study that met standards was conducted on students very similar to yours. Clicking on the indicator for a study will provide information on the similarity for each of the characteristics you selected.
