There is a substantial amount of evidence supporting the use of IGDIs in infant-toddler programs. In addition to our IGDI book published by Brookes, the following peer-reviewed articles provide theoretical and empirical evidence demonstrating how IGDIs can be used to improve infant-toddler programs through 1) efficient progress monitoring, 2) data-based decision making, and 3) outcome reporting to parents, teachers, specialists, funding agencies, and other key stakeholders.
