Galileo Pre-K 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 can 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.
ATI has been supporting Head Start programs throughout the country since 1986. We celebrate Head Start Awareness in October for the unwavering efforts Head Start has made in assisting over eight million low-income preschool children and their families.*
Galileo Pre-K Online supports Head Start efforts to prepare children for kindergarten and beyond by providing a complete and fully integrated assessment, curriculum, and reporting system that links assessment, planning, individualization and program progress. Galileo also provides an estimated measure of what a child has learned in the form of a Developmental Level (DL) score. ATI applies procedures based in Item Response Theory (IRT) to information gained through observational assessment to estimate a measure of child learning. This estimate is presented as the Developmental Level (DL) score. The DL score indicates a child's position on a developmental path and provides information about the capabilities the child has learned as well as the capabilities the child is ready to learn. ATI recently released new research briefs presenting child growth findings which can assist Head Start educators with interpreting DL scores:
- Estimated Growth for Children Birth through 5 Years Based on 2014-15 Assessment Data: The change in the DL score over time can be used to evaluate child growth. ATI’s research can 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
- Predicted Developmental Level Scores for Children Birth through 5 Years Based on 2014-15 Assessment Data: ATI conducts annual research that can be used to predict the DL score for children at various ages. Early childhood providers can use the up-to-date information provided by this research to evaluate whether children are progressing appropriately over time for each age-range. Read the full brief

Galileo Pre-K Online is a reliable and valid assessment tool that can be used to define, assess, and track learning. Galileo applies procedures based in Item Response Theory (IRT) to information gained through observational assessment to estimate a measure of child learning for each age range scale. This estimate of child learning is presented as the Developmental Level (DL) score.
ATI conducts research and analysis each year creating resources to help evaluate children’s learning. Two DL score analysis research briefs are now available:
Predicted Developmental Level Scores for Children Birth through 5 Years Based on 2014-15 Assessment Data
The predicted DL score helps you evaluate your children’s learning at various ages relative to the predicted DL score for children that age. Having this information early in the program year means you can identify children whose DL score is higher or lower than predicted and provide them enrichment and or intervention activities to further their development.
Estimated Growth for Children Birth through 5 Years Based on 2014-15 Assessment Data
In Galileo, growth is defined as a child’s change in his or her DL score. To help determine the estimated growth of children over various time periods, ATI looked at the relationship between a child’s DL score and time (in days). From this analysis, ATI was able to determine the estimated daily growth rate.
