Orthotist & Prosthetist

 What is an ABC Certified Practitioner?

An ABC certified orthotist and/or prosthetist is an allied health professional  specifically educated and trained to make and fit orthoses and prostheses and manage comprehensive orthotic and/or prosthetic patient care. As ABC practitioners, these individuals are certified to independently provide or supervise the provision of patient care.

ABC's Certified Orthotist an​d/or Prosthetist Scope of Practice details the specific functions of certified practitioners. This includes patient assessment, formulation of a treatment plan, implementation of a treatment plan, follow-up and practice management.  

Additionally, certified practitioners are required to support and conform to the ABC Code of Professional Responsibility which promotes and assures the overall welfare of the patient and the integrity of the profession.​


Candidates who have met the ABC requirements and passed all three certification exams will be awarded the Certified Orthotist (CO) or Certified Prosthetist (CP) credential. Candidates who have met the ABC requirements and passed all certification exams for both disciplines will be awarded the Certified Prosthetist Orthotist (CPO) credential​.

 International Recognition

​The International Society for Prosthetics and Orthotics (ISPO)has awarded ABC and the National Commission on Orthotic and Prosthetic Education (NCOPE)​ Category I recognition. 

The Category I recognition validates the ABC/NCOPE pathway for its Certified Prosthetist Orthotist certification program. With this recognition the ABC/NCOPE CPO pathway is recognized throughout the world as having met the highest international educational standards in existence today. ABC is the only credentialing body in the United States to receive Category I recognition from ISPO.
