Research helps early educators evaluate children’s growth

New research from Assessment Technology Incorporated (ATI) provides early childhood programs with expected growth rates for children from birth through 5 years in multiple areas of learning such as language, physical development and health, and social and emotional development.

Using the growth rates, programs can evaluate whether children are meeting growth expectations and whether learning opportunities need to be adjusted to promote growth.

ATI Research Scientist, Dr. Sarah Callahan, states, “Early childhood educators are charged with providing children with appropriate learning opportunities and tracking child growth. The results of this research give educators empirical information about how much growth children of different ages can be expected to show in each area of learning over a given time period. This critical information helps educators evaluate whether the learning opportunities provided to children are supporting adequate growth.”

The data for the studies were collected by over 80 early childhood programs in 40 states as part of ongoing observational assessments conducted during the 2012-13 program year using ATI’s Galileo® Pre-K Online technology.

Galileo provides early childhood educators with a complete assessment, curriculum, and reporting system supporting the evaluation of child progress and the planning of developmentally appropriate learning opportunities.

Galileo uses procedures based in Item Response Theory to translate observational assessment data into an estimate of child ability for each area of learning, the Developmental Level (DL) score. Child growth can then be measured via the change in DL score over time.

In the current studies, ATI conducted regression analyses to establish the expected growth rate for various age ranges and areas of learning based on the observed change in child DL scores over time.

Results revealed that growth rates typically increased as a child’s age increased; however, growth rates for children in a given age range were similar across different areas of learning.

Results also indicated that children can be expected to show about as much growth from birth to 3 years as they do each year thereafter from 3 through 5 years.
