The Achievement Gap

The achievement gap begins for many students before they enter the Kindergarten classroom. Children aren´t born with a vocabulary, yet educators and reading researchers have long identified the differences in word knowledge and vocabulary as key indicators of student readiness. Here are a couple of key findings:

A gap of 30 million words in language experience exists for some children prior to entering school. In 1995, Hart and Risley published findings from a study showing vast differences in the quantity and quality of language experience in the homes of children during the first 4 years of life.

Infants and young children with inadequate language development are at-risk for developing academic difficulties.¹ Without effective intervention, the majority of these students will exit high school with academic skills well below grade level.²
