Individual Growth and Development Indicators (IGDIs) for Infants and Toddlers

Measures designed to monitor progress and individualize services for children from 6 months to 42 months of age.

Why use IGDIs?

  • Assess child outcomes using 6-minute, standardized, play-based assessments
  • Get a quick ‘snapshot’ of a child’s progress on key outcomes
  • Make data-based decisions about intervention and services
  • Share child progress with parents and other providers
  • Provide reports to stakeholders about program impact

Answers to the following questions should help you determine if IGDIs would be a good fit for your program. Also, see our Scoring and Administration Frequently Asked Questions (FAQs) for additional information.


With what age group should IGDIs be used?

Infant and Toddler IGDIs may be used with children from ages 6 months to 42 months of age. 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.

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.

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.

The Early Social Indicator (ESI) measures key social skills for infants and toddlers from 6 months to 42 months.

Learn more about what IGDIs measure.


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 video taped administration, scoring generally takes about 15 minutes to score and enter into the data system.

Learn more about IGDI administration.


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?

Certification requires participation in a workshop provided by IGDI staff. Go to our Certification Steps page to learn more.


How much do they cost?

Information about cost structure for the IGDIs can be found by following this link:  Cost Structure for Training

Currently, there is no fee for using the online data system after training or for the IGDI forms.

Costs for toys will vary.  Please check purchasing information for each toy set that you will need.
