Occupational Therapy Assistant Primary Specialty

NUCC Taxonomy Code: 224Z00000X

State License FL OTA15535

An occupational therapy assistant is a person who has graduated from an occupational therapy assistant program accredited by the Accreditation Council for Occupational Therapy Education (ACOTE) or predecessor organizations, has successfully completed a period of supervised fieldwork experience required by the accredited occupational therapy assistant program, has passed a nationally recognized entry-level examination for occupational therapy assistants, and fulfills state requirements for licensure, certification, or registration. An occupational therapy assistant provides interventions under the supervision of an occupational therapist which emphasize the therapeutic use of everyday life activities (i.e., occupations) with individuals or groups for the purpose of facilitating participation in roles and situations and in home, school, workplace, community and other settings. Occupational therapy services are provided for the purpose of promoting health and wellness and are provided to those who have or are at risk for developing an illness, injury, disease, disorder, condition, impairment, disability, activity limitation, or participation restriction. Occupational therapy assistants address the physical, cognitive, psychosocial, sensory, and other aspects of occupational performance in a variety of contexts to support engagement in everyday life activities that affect health, well-being, and quality of life.

Early Intervention Provider Agency

NUCC Taxonomy Code: 252Y00000X

Early intervention services are an effective way to address the needs of infants and toddlers who have developmental delays or disabilities. The services are made available through a federal law known as the Individuals with Disabilities Education Act (IDEA). IDEA provides states and territories with specific requirements for providing early intervention services to infants and toddlers with special needs. In turn, each state and territory develops its own policies for carrying out IDEA and its requirements. Broadly speaking, early intervention services are special services for eligible infants and toddlers and their families. These services are designed to identify and meet children's needs in five developmental areas. These areas are: physical development, cognitive development, communication, social or emotional development, and adaptive development.
