 What and Why?


NIH Toolbox is a multidimensional set of brief measures assessing cognitive, emotional, motor and sensory function from ages 3 to 85, meeting the need for a standard set of measures that can be used as a “common currency” across diverse study designs and settings. 

NIH Toolbox monitors neurological and behavioral function over time, and measures the domain constructs across developmental stages. This facilitates the study of functional changes across the lifespan, including evaluating intervention and treatment effectiveness.

    This subscription may be used on any iPad on which you install the NIH Toolbox app, as long as you enter the same Apple ID used for purchase. The subscription includes support for installation on up to 10 iPads.
