Podiatrists consult with and refer patients to other health practitioners when necessary.
The first two years concentrate on classroom instruction and laboratory work in the basic sciences. The third and fourth years of study focus on the clinical sciences and patient care. Most graduates complete a hospital residency program lasting from one to three years. To obtain a license to practice as a podiatrist, one must be a graduate of an approved school of podiatric medicine, have a passing score on the national exam and pass state written and oral exams. There is a number of certifying boards for the podiatric specialties of orthopedics, primary medicine or surgery.
