National Institutes of Health Infant and Toddler Toolbox
The NBT is a five-year research project designed to create a new national norm for administering, scoring, and interpreting infant and toddler assessments of cognition, social functioning, language (receptive and expressive), early mathematics/numeracy, self-regulation, and executive function in children between 1- and 42-months of age. Assessments will include direct child assessment and observations supplemented as needed by reporting from parents or legal guardians.
