Overview

• Developed by Northwestern University researchers, the suite extends the NIH Toolbox to infants and integrates with existing measures for seamless longitudinal tracking.
• The assessments run on an iPad using videos and eye-tracking to evaluate cognitive, language, motor, and social-emotional skills in preverbal children.
• A norming and validation study of more than 2,500 infants and toddlers from English- and Spanish-speaking households reported high test–retest reliability.
• The tool features automated scoring, no per‑patient costs, and reduced training and administration time for clinical and research settings.
• An eight-article special issue of Infant Behavior and Development details the methods and norms, and the resource is available at nihbabytoolbox.org.
