myIGDIs (“Individual Growth & Development Indicators”) are a comprehensive set of Early Childhood Assessments for monitoring the growth and development of young children. myIGDIs, pronounced my-IG-deez, were originally developed in a collaborative effort under the Early Childhood Research Institute on Measuring Growth and Development at the University of Minnesota. As of 2004, more than 35% of Early Reading First grantees used myIGDIs to assess child language and literacy outcomes. Today, myIGDIs are the only RtI (Response to Intervention) -oriented early childhood measures and have been used across over 12,000 school settings. Furthermore, the myIGDIs assessment suite has recently expanded with a revised version of early literacy measures and addition of early numeracy probes.
