Indicators of Individual Growth and Development for Infants and Toddlers (IGDI) measure development outcomes for children between 6 and 42 months. IGDI assessments are evaluations of 6-minute play sessions with the child and require the use of a set of toys in addition to administration materials. IGDI assessments can be conducted live during the play session, based on a video recording of the play session, or by observing the play session virtually.
