Infant/Toddler Environment Rating Scale (ITERS-3) - Debby Cryer, Thelma Harms, Richard M. Clifford, Noreen Yazejian

This revised and updated assessment tool focuses on the full range of needs of infants and toddlers up to 36 months of age and provides a framework for improving program quality. ITERS-3 assesses both environmental provisions and teacher-child interactions that affect the broad developmental milestones of infants and toddlers, including: language, cognitive, social-emotional and physical development as well as concern for health and safety.
