Efficacy of a Supplemental Small-Group Early Literacy Intervention Implemented by Early Childhood Educators.

Purpose: Phonological awareness and alphabet knowledge are fundamental building blocks for literacy development. We identified preschoolers with persistent delays in these skills and evaluated the efficacy of a supplemental curriculum to remediate deficits in early literacy skills.

Method: Using a cluster design, 21 classrooms were randomly assigned to early literacy versus language intervention conditions.
