Project TIE (Teams in Early Intervention) was conceptualized to meet the need for: (1) involvement of formerly "ancillary" service professionals in early intervention for children with disabilities, (2) high quality family-centered services, and (3) training in the team approach. The project provides training to four groups that might constitute an early intervention team--speech/language pathologists, motor therapists, health care professionals, and family members. This training module on occupational therapy and physical therapy outlines reasons for consulting with occupational/physical therapists (OT/PTs) as members of the interdisciplinary team; explores areas of information that should be shared between OT/PTs and health care professionals, speech/language pathologists, and family members; discusses what health care professionals can expect from an ongoing collaboration with an occupational/physical therapist; offers a mechanism for determining what other team members want from OT/PTs; and examines how OT/PTs' expertise can be applied to the Performance Competence Model to understand how children interact with their environment. Three overheads and handouts are appended. (JDD)
