New 2015-16 ATI Research Briefs Assist Pre-K Programs Interpreting
Developmental Level (DL) scores

Galileo Pre-K Online is a reliable and valid assessment tool that can be used to define, assess, and track learning. ATI applies procedures based in Item Response Theory (IRT) to information gained through observational assessment to estimate a measure of child learning called the DL score. The DL score indicates a child's position on a developmental path and provides information about which capabilities the child has learned and which capabilities the child is ready to learn. Each year, ATI conducts research to evaluate how a child's DL score relates to both a child's age as well as to the time a child is enrolled in a preschool program. The results of the research are summarized in the following two research briefs and can be used to gauge child growth.
