ABC CTPO is the dual-discipline fabrication technician credential — pass BOTH 125-item CTO and CTP exams. Master orthotic fabrication (polypropylene vacuum forming, AFO/KAFO/TLSO, scoliosis bracing) AND prosthetic fabrication (test sockets, definitive lamination, alignment hardware, knees/feet/pylons) plus shared materials and OSHA shop safety.

About the CTPO Exam
ABC dual-discipline technician-level fabrication credential — combines CTO + CTP. Awarded after passing BOTH the Orthotic Technician and Prosthetic Technician exams (125 items each, 250 total). Covers shared fabrication techniques (vacuum forming, lamination, plaster modification, CAD/CAM), orthotic content (AFO/KAFO/TLSO/cervical fabrication), prosthetic content (socket/component fabrication), shared materials, and OSHA shop safety.

Frequently Asked Questions
How is the CTPO credential earned?
CTPO is granted after passing BOTH the CTO exam AND the CTP exam (125 items each, separate sittings). Eligibility typically requires 4 years of O&P fabrication experience covering both disciplines, or completion of an ABC-approved dual-discipline technician program. The exams may be taken in any order; both must be passed within the application window.
Why pursue CTPO vs CTO or CTP alone?
CTPO demonstrates fabrication competency across both orthotic and prosthetic shop work — valuable in O&P facilities offering both services. Many small/independent O&P labs need versatile technicians who can build AFOs in the morning and laminate prosthetic sockets in the afternoon. The dual credential expands employability and may command higher pay.
What is the role of a CTPO in an O&P clinic?
A CTPO works in the fabrication shop under the direction of an ABC-certified Orthotist, Prosthetist, or CPO. They build custom orthoses and prostheses to specifications: vacuum forming AFOs, modifying plaster molds, laminating sockets, assembling pylons and knee/foot components, fabricating cosmetic finishes. They do NOT independently assess patients or prescribe devices.
How should I study for ABC CTPO?
Plan 100-160 hours total over 12-20 weeks for both exams. Use CTO + CTP materials in parallel; many topics overlap (vacuum forming, lamination, OSHA shop safety, materials properties). Sit the discipline you fabricate most often first. Hands-on shop work is essential — pair every topic review with shop bench practice.
