Welcome to IGDI's for Infants and Toddlers

This web site is dedicated to assessing the results of early intervention and early childhood special education services provided young children birth through age 3. Indicators of Individual Growth and Development for Infants and Toddlers (IGDI's) are a set of measures designed and validated for use by early childhood practitioners and interventionists for the purpose of monitoring children's growth and progress. Unlike standardized tests that are administered infrequently, IGDI's are designed to be used repeatedly by practitioners in order to estimate each child's "rate of growth" over time. The distinctive benefit of this approach is that the information can be used to directly inform intervention design, implementation, and modification at reasonable levels of training, time, and cost.

Information for the Barn (toy set used for the ECI)

• Recall: If you purchased your barn before June 17, 2002, it is not included in the recall. If your barn was purchased after that date, please have your barn with you and go to the Mattel Recall website to check on the safety of your specific toy.
• 'Hairy' animals: Fisher-Price has started making the farm animals with synthetic 'hair.' We recommend purchasing Barns without the synthetic hair to allow proper cleaning of toys. Go to the ECI Toy Purchasing page for a list of replacement animals (in case you have purchased this version) and an alternative barn set.
