Since you will measure, make and fit shoe inserts to correct problems and deformities in patients' feet, put emphasis on classes in biology, anatomy, chemistry and physics. Take any medical or health-oriented classes your high school offers. Any shop course, like woodworking or welding, will hone the skills needed to constructs orthoses.
Complete a bachelors degrees in orthotics. Many accredited medical schools offer orthotics as a major. You will learn how to examine a patient's foot or other limbs to determine the type of appliance needed and make a plaster cast of the area. Then you will design and build the appliance and fit it on the patient, making adjustments as needed.
Learn how to make leg braces and other individualized aids to assist patients with standing and walking. An orthotist works closely with doctors, therapists and chiropodists. You must know how to interpret prescriptions and keep diligent patient records.
Obtain a residency at a hospital, clinic, private practice or rehabilitation facility. By working under the supervision of a qualified orthotist, you'll gain experience fitting and counseling patients and increase your skills measuring and designing.
Acquire certification from the National Commission on Orthotic and Prosthetic Education (NCOPE) as a fitter. This organization sets professional criteria for new and existing orthotists. You must complete a fitter education lab course for official approval by the NCOPE to become a certified orthotist.
