Ongoing Assessment to Support Data-Driven Decisions

Galileo Pre-K enables multi-method, standards-based, authentic assessment of children from infancy through 5 years via observation in the child’s learning environment, one-on-one observation, work samples, and parent input. Galileo is backed by ATI's research program which establishes, on a continuous basis, the reliability, validity, and psychometric properties of Galileo assessment scales. Assessment tools within Galileo Pre-K Online are fully integrated with curriculum and reporting tools that provide users with valid, reliable data on which to base lesson planning for individuals and groups. Galileo reports can be generated at various levels of aggregation to support the tracking and documentation of child progress towards standards mastery and school readiness. Galileo Pre-K can support the goals of early childhood programs by providing:

comprehensive assessment system
  • an authentic observational assessment system for birth through 5 years that includes research-based assessment scales to measure cognitive, social, and physical development
  • readiness levels (i.e. Learned, Plan Now, Plan Soon, and Plan Later) for every scale goal which identify the capabilities each child is likely ready to learn next. These levels offer information which can establish initial developmental profiles that help teachers record and monitor learning throughout the year as well as guide developmentally appropriate lesson planning
  • comprehensive and adaptable developmental assessment using psychometric analyses to establish reliability and validity of assessment instruments
  • support for ongoing assessment in the child's natural environment
  • organized assessment data from multiple sources, such as teacher observations, parent input, and classroom projects, into one integrated development profile
  • programs the ability to add or delete scale indicators, create new scales, modify scales for local interests or special needs, and translate any scale into a different language
  • a Developmental Screening scale for children ages 3 through 5 years to help teachers identify children who may be at risk of developmental delay
  • anecdotal note taking capabilities to help create consistent, clear records which may be provided through the Galileo Pre-K Parent Center, a secure area within Galileo Pre-K Online where parents can access up-to-date information about a child’s learning and classroom experiences

Real-time Assessment Results Guiding Instruction

Galileo's state-of-the-art assessment system provides continuous data that drives decisions to improve child outcomes.

Integrated Multi-Method Observational Assessment Tools

Galileo's authentic assessment approach may occur one-on-one, in small groups, and in large groups. Assessment data gathered by teachers provides information to guide decision-making at the classroom and program level. With the integration of assessment and curriculum, educators are provided with a seamless link between ongoing information on children’s development and empirically based recommendations for learning opportunities that can be provided to help facilitate further learning.

Standards-Based Scales Supporting Curriculum and Assessment

The Galileo G3 Scales for children birth through 5 years are aligned with state and national early learning standards and guidelines. The scales are comprised of in-depth, comprehensive, and empirically-based developmental sequences for Galileo capabilities in 12 domains of knowledge. The scales form the foundation of Galileo assessment tools and are appropriate for dual language learners and children with disabilities.

  • Nature and Science
  • Technology

Measurement Expertise and Ongoing Research

Galileo scales have been normed on tens of thousands of children across multiple states using Item Response Theory (IRT) technology widely used in statewide assessment programs. Galileo also provides an estimated measure of what a child has learned in the form of a Developmental Level (DL) scale score. ATI applies procedures based in IRT to information collected through observational assessment to produce the DL score. The score indicates a child's position on a developmental path and provides information about the capabilities the child has learned and the capabilities the child is ready to learn. Ongoing research supports the reliability, validity, and effectiveness of these scales in documenting child learning outcomes and guiding the planning of developmentally appropriate learning opportunities.

ATI's research briefs present child growth findings. Learn how a child's age or the amount of time a child is enrolled affects 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. Use this research to estimate child growth for various time periods and to evaluate whether children are demonstrating adequate growth over time.

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. Use this information to evaluate whether a child is progressing appropriately over time for his/her age.

Interoperability with Other Systems

Galileo interfaces are available to support automated data extraction for transfer to data warehouses and other systems that might be implemented as part of a statewide initiative. Additionally, ATI offers specific professional development assisting teachers and program staff to develop the knowledge and skills required to reliably conduct observational assessments.  Learn more

Acuscreen Developmental Screening

Acuscreen is a 45-day developmental screening tool designed to help educators determine whether or not a child should be referred for diagnostic testing aimed at determining the child's eligibility for special services. When used with Galileo Online, Acuscreen data can be stored, aggregated, and used to generate an individualized education plan.
