Overview

• The tablet-based battery uses videos and gaze-based learning paradigms to assess cognitive, language, motor, and social-emotional skills in infants and toddlers.
• A norming study with over 2,500 participants from English- and Spanish-speaking households showed high test–retest reliability and supports broad scalability.
• An eight-article special issue of Infant Behavior and Development detailing development and validation is available online, with a print edition due in September.
• Development drew on a survey of more than 400 domain experts and a systematic literature review, leading to adapted and newly created measures suited for iPad use.
• The app is available via the project website, and developers report automated or guided scoring, no per-patient costs, reduced training time, and seamless linkage with the original NIH Toolbox for longitudinal assessments.
