DC:0–5™ Manual and Training


DC:0-5 is an essential tool for counselors, doctors, nurses and many more evaluating and treating very young children and their families.
In 1994, ZERO TO THREE published its groundbreaking manual, DC:0–3 Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood. The first developmentally based system for diagnosing mental health and developmental disorders in infants and toddlers, this critically important guide quickly became an indispensable resource for mental health clinicians, counselors, physicians, early interventionists, educators, and researchers, and established ZERO TO THREE as a leading authority in the field of infant mental health.DC:0–5 and associated ZERO TO THREE DC:0–5 Training build on the powerful legacy of the DC:0-3 using the latest scientific findings and clinical research. ZERO TO THREE is the only official training provider for DC:0–5. The curricula have been designed to meet the needs and interests of multiple audiences through a variety of modalities consistent with the content and approach of DC:0-5.
Currently there are four main categories of DC:0-5 training offerings: Official DC:0-5 Training
