With what age group should IGDIs be used?
Infant and Toddler IGDIs may be used with children from ages 6 months to 42 months (3.5 years). For information about IGDIs for preschool children, please visit the MyIGDIs website.
What do IGDIs measure?
The Early Communication Indicator (ECI) measures key expressive communication skills (gestures, vocalizations, single words, and multiple words) for infants and toddlers from 6 months to 42 months (3.5 years).
The Early Movement Indicator (EMI) measures key gross motor skills (transitional movements, grounded locomotion, vertical locomotion, throwing/rolling, and catching/trapping) for infants and toddlers from 6 months to 42 months (3.5 years).
The Early Problem Solving Indicator (EPSI) measures key cognitive/problem solving skills (looking, exploring, functions, and solutions) for infants and toddlers from 6 months to 42 months (3.5 years).
The Early Social Indicator (ESI) measures key social skills for infants and toddlers from 6 months to 42 months (3.5 years).
How long do IGDIs take to administer and score?
Each IGDI assessment takes 6 minutes to administer. If scoring live, the scoring is complete at the end of the 6-minute IGDI session. Entering scores into the data system should take less than 5 minutes. If scoring from a videotaped administration, videos generally take about 15 minutes to score and enter into the data system.
How often can IGDIs be administered?
IGDIs are very sensitive to changes in growth, even small ones! Unlike other standardized measures, IGDIs are designed to be used repeatedly. This may mean bi-monthly, monthly, or quarterly.
How do I get certified?
