WWC Summary of Evidence for this Intervention
Sound Foundations
Sound Foundations, a literacy curriculum designed to teach phonological awareness to preliterate children, focuses exclusively on phoneme identity (that is, different words can start and end with the same sound). It works from the principle that phonemic awareness is necessary but not sufficient to reading. The curriculum is self-contained and can be used by teachers, parents, or teaching assistants.

An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
For more, please see the WWC Glossary entry for improvement index.
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.
