The goal of the project was to review the knowledge base related to the use of technology to support the practice of early childhood professionals who work directly with children and families. To accomplish this goal, the review answers seven specific research inquiries within four Topic Areas of interest to ACF/OPRE (see Table 1). The first three Topic Areas describe early childhood practitioners' use of technology while the fourth Topic Area outlines barriers and facilitators of practitioners' effective use of technology to support early childhood practice.
