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.
- Estimated Growth for Children Birth through 5 Years Based on 2015-16 Assessment Data: The change in the DL score over time can be used to evaluate child growth. ATI's research may be used to estimate child growth for various time periods. This information can be used by early childhood providers to evaluate whether children are demonstrating adequate growth over time. Read the full brief. See sample excerpt of data below.
- Predicted Developmental Level Scores for Children Birth through 5 Years Based on 2015-16 Assessment Data: ATI conducts annual research that can be used to predict the DL score for children at various ages. Early childhood providers may use the up-to-date information provided by this research to evaluate whether children are progressing appropriately over time relative to their peers. Read the full brief. See sample excerpt of data below.
