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

This early literacy intervention package had practical benefits, with 90% of experimental group preschoolers exceeding the phonemic awareness benchmark for beginning kindergarten compared to 45% in the comparison group, for example. Providing preschool teachers with tools and support for implementing a tiered approach to early literacy intervention holds promise for producing impressive gains in skills required for children to succeed in later schooling.
