IGDI Measures

There are four Infant-Toddler IGDI measures for children 6 months to 42 months of age. Each measure has similar administration guidelines (e.g., six minutes, play-based, observational, growth charts), but each measure has different child behaviors to be coded by certified staff. Each IGDI has a specific general outcome that was used to select the specific behaviors to be coded.

- The Early Communication Indicator (ECI) measures a child’s expressive language. The general outcome for the ECI is that the child uses gestures, sounds, words, or sentences to convey wants and needs or to express meaning to others. Key skills for the ECI are: gestures, vocalizations, single words, and multiple words.
