Diving Deeper into the Domains series builds on TPBA2: The Essentials training to provide opportunities for team members to become more familiar with each domain. It is critically important that every team member becomes familiar with the content of each domain as well as how the domains overlap and support one another. This session is intended for new evaluation team members inclusive of these roles: psychologists, speech-language pathologists, occupational therapists, physical therapists, play facilitators, and parent facilitators.
