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.
Monitoring individual children’s growth on the ECI can be important for:
Making individual intervention decisions
Providing helpful information on program progress
Informing programmatic decisions regarding this essential outcome
Indicating program results when used at a state-wide level
