Orthotists and prosthetists are highly specialized allied health professionals who design, fabricate, and fit orthoses (braces and supports) and prostheses (artificial limbs) for patients with musculoskeletal conditions and limb loss. With an aging population, rising rates of diabetes-related amputations, and advances in materials and technology, demand for qualified O&P practitioners continues to grow. The path to becoming a certified orthotist or prosthetist involves graduate education, a clinical residency, national certification, and -- in many states -- a separate state license.

This guide walks you through every step of the process, from choosing a CAAHEP-accredited graduate program to completing your clinical residency, passing the ABC certification exam, meeting state licensing requirements, and maintaining continuing education. We have also compiled verified data for all 51 states we track so you can compare requirements side by side.

What Does an Orthotist/Prosthetist Do?

Orthotists and prosthetists are allied health professionals who specialize in the design, fabrication, and fitting of orthopedic devices. Orthotists design, fabricate, and fit orthoses -- braces, supports, and other devices -- for patients with musculoskeletal conditions, neuromuscular disorders, and injuries. Prosthetists design, fabricate, and fit prostheses -- artificial limbs and other devices -- for patients who have undergone amputations. Some practitioners are certified in both disciplines and hold the CPO (Certified Prosthetist-Orthotist) credential.

The day-to-day work of an orthotist/prosthetist typically involves:

• Patient evaluation: Assessing patients' physical conditions, functional needs, and goals in collaboration with referring physicians and rehabilitation teams.
• Measurement and casting/scanning: Taking precise measurements, casts, molds, or digital scans of the affected body part to create a custom device.
• Device design and fabrication: Using advanced materials (carbon fiber, thermoplastics, metals, silicone) and CAD/CAM technology to design and build orthoses or prostheses.
• Fitting and adjustment: Fitting the device to the patient, making precise adjustments for comfort, function, and alignment.
• Follow-up care: Monitoring patient progress, making modifications as needed, and ensuring long-term device function and patient satisfaction.

Orthotists and prosthetists work in a variety of settings, including:

• O&P practices: Private or group practices specializing in orthotic and prosthetic care.
• Hospitals: Inpatient and outpatient orthopedic and rehabilitation departments.
• VA facilities: The U.S. Department of Veterans Affairs is one of the largest employers of O&P professionals, serving veterans with limb loss and musculoskeletal conditions.
• Rehabilitation centers: Comprehensive rehabilitation facilities serving patients recovering from trauma, stroke, and other conditions.

According to the U.S. Bureau of Labor Statistics, the median annual wage for orthotists and prosthetists is approximately $75,000--$80,000, with salaries varying by experience, geographic location, and practice setting. Practitioners in high-demand areas or with specialized expertise can earn significantly more.

Step 1: Education Requirements

Bachelor's Degree

There is no single required undergraduate major to enter an orthotics and prosthetics graduate program, but degrees in biomedical engineering, biology, kinesiology, anatomy, or a related science provide the strongest preparation. Prerequisite coursework typically includes human anatomy, physiology, physics, statistics, and psychology. Some programs may also require courses in biomechanics or materials science.

Master's Degree from a CAAHEP-Accredited Program

The orthotics and prosthetics profession currently requires master's-level entry. Candidates must complete a master's degree from a program accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP). CAAHEP-accredited O&P programs are housed at universities across the United States and provide rigorous training in the science and clinical practice of orthotics and prosthetics.

A qualifying graduate program in orthotics and prosthetics includes coursework in:

• Biomechanics and pathomechanics
• Materials science and fabrication techniques
• Lower extremity orthotics and prosthetics
• Upper extremity orthotics and prosthetics
• Spinal orthotics
• Patient assessment and clinical decision-making
• Research methods and evidence-based practice
• Clinical rotations in orthotic and prosthetic care settings

Program length is typically 2--2.5 years of full-time study. Clinical rotations are an integral component, providing hands-on experience in patient care, device fabrication, and fitting under the supervision of experienced practitioners.

Step 2: Clinical Residency

After completing your master's degree, you must complete a 1-year supervised clinical residency in orthotics and/or prosthetics. The residency provides intensive, hands-on patient care experience under the direct supervision of a certified and licensed orthotist or prosthetist.

Key residency requirements:

• Duration: A minimum of 1 year (12 months) of full-time supervised clinical practice.
• Disciplines: Residents may complete a residency in orthotics only, prosthetics only, or both (for those pursuing the CPO credential). Dual-discipline residencies are longer.
• Patient care competencies: Residents must demonstrate competency across a defined set of patient care activities, including evaluation, device design, fabrication, fitting, and follow-up care.
• Supervision: The residency must be supervised by an ABC-certified practitioner (CO, CP, or CPO) who meets the credentialing body's supervisor requirements.
• NCOPE accreditation: Residency programs are accredited by the National Commission on Orthotic and Prosthetic Education (NCOPE), which sets standards for residency training.

Residency sites include O&P practices, hospitals, VA facilities, and rehabilitation centers. Securing a competitive residency position often requires strong clinical rotation performance and faculty recommendations from your graduate program.

Step 3: ABC Certification

The American Board for Certification in Orthotics, Prosthetics & Pedorthics (ABC) is the primary national credentialing body for orthotists and prosthetists. After completing your master's degree and clinical residency, you are eligible to sit for the ABC certification examinations.

ABC offers the following credentials:

• CO (Certified Orthotist): For practitioners specializing in orthotic care.
• CP (Certified Prosthetist): For practitioners specializing in prosthetic care.
• CPO (Certified Prosthetist-Orthotist): For practitioners certified in both orthotics and prosthetics.

The ABC certification examination consists of two parts:

• Written examination: A comprehensive multiple-choice exam covering clinical knowledge, patient management, device design, biomechanics, and professional practice.
• Practical/simulation examination: A hands-on exam that tests clinical skills, including patient evaluation, device fabrication, fitting, and adjustment in simulated clinical scenarios.

In addition to ABC, the Board of Certification/Accreditation (BOC) offers an alternative certification pathway for orthotists and prosthetists. Some states accept BOC certification in addition to or in lieu of ABC certification. Check your state's specific requirements to determine which credential is accepted.

State-by-State Orthotist/Prosthetist Requirements

Requirements vary significantly by state. Some states mandate a separate state license in addition to national certification; others rely entirely on national certification. Click any state name to see its complete licensing guide with step-by-step instructions, fees, CE details, and more.

Continuing Education Requirements

Maintaining your ABC certification and state license requires ongoing continuing education (CE). Requirements exist at two levels: the ABC national certification and state licensure.

ABC Continuing Education

ABC requires all certified orthotists and prosthetists to complete 75 continuing education credits per 5-year renewal cycle. CE credits can be earned through a variety of approved activities, including:

• Professional conferences and workshops (such as those offered by AOPA and state O&P associations).
• University courses and online continuing education programs approved by ABC.
• Published research, presentations, and professional service activities.
• ABC requires a portion of CE credits to be in specific content areas, including patient care, professional ethics, and practice management.

State License Continuing Education

States that issue a separate orthotist/prosthetist license often have their own CE requirements for license renewal, which may or may not align with ABC's 75-credit requirement. Across the 51 states we track, the average CE requirement is 0 hours per renewal cycle. Some states accept ABC-approved CE toward state license renewal; others require state-specific coursework, including instruction in state laws and regulations.

Tips for managing CE requirements efficiently:

• Track your credits year-round rather than scrambling at renewal time. ABC's online portal allows you to log CE activities.
• Attend the AOPA National Assembly or your state O&P association's annual conference -- these events typically offer substantial CE credits in a single weekend.
• Look for "double-dipping" opportunities where a single CE activity satisfies both ABC and state license renewal requirements.
• Stay current with advances in materials, CAD/CAM technology, and microprocessor-controlled devices -- these are rapidly evolving areas of the profession.
