The ECEI’s Infant-Toddler Workgroup was formed in Spring 2020 to examine measures available to our research group to assess very young children, specifically infants and toddlers. We were especially interested in identifying assessments that were new to us and the field. The ECEI staff is trained on and use a variety of child assessments in our applied research. However, many of those measures are primarily designed for use with children age 3 and older. We have found that although we have many child assessments that examine various developmental areas for children over 36 months, there are fewer choices of child assessments designed for use with children younger than 36 months of age. Many of the classrooms at our local partnership schools are designed to serve very young children (from birth to 3); thus there is a noticeable gap in the information we are able to provide. The intention of the ECEI’s Infant-Toddler Workgroup was to seek out and learn more about child assessment measures available for use with children under 36 months of age. (author abstract)
