WWC Summary of Evidence for this Intervention
Leveled Literacy Intervention
Leveled Literacy Intervention (LLI) is a short-term, supplementary, small-group literacy intervention designed to help struggling readers achieve grade-level competency. The intervention provides explicit instruction in phonological awareness, phonics, fluency, vocabulary, reading comprehension, oral language skills, and writing. LLI helps teachers match students with texts of progressing difficulty and deliver systematic lessons targeted to a student’s reading ability.

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.
