Learn to heal attachment 
wounds and trauma in children.

Early experiences within attachment systems form the threads that weave the fabric of every human being.  A safe and secure attachment system builds resilience for a lifetime while attachment traumas and toxic stress can erode mental and physical health and well-being. 

Treating Developmental Trauma and Attachment in Children (TDTAC) is an 80-hour, post-graduate level course for mental health professionals in the fields of child welfare, children’s mental health and adoption / permanency. The course consists of 44 hours of self-directed learning of resources that will be provided, 30 hours of on-line or in-person class, and 6 hours of knowledge implementation classes. TDTAC combines the recent research on Interpersonal Neurobiology with the physiological and relational practices. After completion, participants will be eligible to register as an ATTACh mental health clinician upon completion. 

The course will focus on the current thinking about childhood developmental trauma through the lenses of attachment and trauma. Current terminologies and schools of thought including Developmental Trauma and ACEs will be explored. Attachment theory, theories of trauma and interpersonal neurobiology will be explored in parallel with current psychotherapeutic modalities and techniques including on sensory, somatic and brain-based traumagenic differences. 

Children who have been separated from primary attachment figures require support for grief and loss. Mitigating grief and loss through therapy and systems work (maintain placement stability, reducing losses, maintaining connections through access and openness) is explored. There will be a number of special topics covered, some by guest speakers, including residential treatment, childhood violence in the home, sexual orientation and gender identity in children, racism and identity formation, historical and intergenerational trauma, and cultural safety. The course will wrap up with a focus on safe and effective use of self and self-care for mental health practitioners. 

To enroll in the TDTAC - Mental Health Certification Course, participants must have a Doctorate or Master’s degree in psychology, social work, or another license in a mental health-related field.
