About this exam

The Certified Orthotic Fitter (COF) credential from the Board of Certification/Accreditation, International (BOC) is a certification for professionals who fit orthotic devices. According to BOC, the COF designation is awarded on the basis of three requirements: completion of a required course of study, experience in patient care under appropriate supervision, and passing a three-hour multiple-choice examination offered four times each year in more than 150 cities. BOC states that it offers the only NCCA-accredited COF certification, and that its certifications span five disciplines: orthotics, prosthetics, pedorthics, orthotic fitting, and mastectomy fitting. BOC reports that COFs practice in hospitals, clinics, alongside orthotists, or independently, and that the streamlined requirements were intended to improve access to care where orthotic and prosthetic practitioners are scarce. BOC has retired the formerly mandatory video practical examination, concluding that the multiple-choice exam is a sufficient assessment tool, so candidates should prepare for a knowledge-based test rather than a filmed practical. To prepare, work through the fitting, measurement, device-selection, and patient-care content of your required course of study, review BOC's published exam study resources, and take practice questions under timed conditions. Confirm current eligibility details, scheduling, and policies directly with BOC before applying.

Common questions

About BOC-COF preparation

What is the exam format?

BOC describes the COF examination as a three-hour multiple-choice examination. BOC states that its decision retired the formerly mandatory video practical examination, so the multiple-choice exam is the assessment tool. Confirm current administration details, including whether testing is remote proctored, directly with BOC before you schedule.

How long is the exam and how often is it offered?

The examination runs three hours and is conducted four times each year in more than 150 cities, according to BOC. Because seats and dates vary by location, schedule early through BOC once your course of study and supervised patient-care experience are complete.

What are the eligibility requirements?

BOC lists three requirements for the COF designation: completion of a required course of study, experience in patient care under appropriate supervision, and passing the three-hour multiple-choice examination. BOC states it has refined and extended its experience requirements. Verify the specific course and experience details with BOC.

Is the COF certification accredited?

BOC states that it offers the only NCCA-accredited COF certification. NCCA, the National Commission for Certifying Agencies, uses peer review to evaluate the administrative, technical, and psychometric aspects of how a certification's requirements and assessment tools are developed and maintained.

How hard is the exam?

BOC does not publish a pass rate in its materials, so difficulty cannot be stated numerically. The exam is a three-hour multiple-choice test built to NCCA psychometric standards. Candidates with completed coursework and supervised fitting experience are best positioned; treat study resources and timed practice as essential preparation.

What if I fail - can I retake it?

BOC's published materials do not state a retake policy, waiting period, or fee for the COF examination. Because the exam is offered four times each year, a retake may be possible at a later administration, but confirm the current policy directly with BOC rather than relying on assumptions.

Does the COF still require a video practical exam?

No. BOC states its decision effectively retires the formerly mandatory video practical examination, which had been intended to demonstrate a fitter's unsupervised abilities. BOC concluded, after multi-year analysis, that the multiple-choice exam was a sufficient assessment tool, and that the video imposed undue burden in time and money.

What study order do you recommend?

Start with the fitting and measurement fundamentals from your required course of study, then device selection and patient-care considerations, then timed practice questions to build pacing for the three-hour exam. Review BOC's exam study resources alongside your coursework. Finish with weak-area review rather than rereading material you already know.

What are common failure modes?

The most common mistakes are underestimating pacing on a three-hour multiple-choice exam, studying only device facts while neglecting supervised patient-care experience, and relying on outdated requirements. BOC has revised the COF pathway, so verify every requirement against BOC's current published information rather than older guides or forums.

Where can COFs work after certification?

BOC states that BOC COFs can practice in a variety of settings: hospitals, clinics, along with orthotists, or independently. BOC adds that the revised requirements were expected to improve access to care, especially in areas where access to orthotic and prosthetic practitioners is limited.
