HTCC ensures that the hand therapy profession is defined accurately and provides a meaningful way to communicate effectively with practitioners, educators, the professional community, and the public. HTCC conducts formal practice analysis / role delineation studies to determine that the professional knowledge and skills assessed in its hand therapy credentialing program are, in fact, limited to those required for competent performance of hand therapy. The routine assessment and review of current practice standards identify reliable indicators of competence in hand therapy practice and creates a valid and defensible empirical foundation for the Hand Therapy Certification Examination (HTCE) and the CHT recertification process.
