Here is what I found from the AACPM on residencies:
http://www.aacpm.org/html/residencies/rp_programs.asp
There are two basic residency models. Each is a combination of medicine and surgery. Residency training is founded on a resource-based, competency-driven, assessment-validated model.
Podiatric Medicine & Surgery 24 (PM&S-24)
A resident in Podiatric Medicine and Surgery is trained in the breadth of podiatric healthcare. Completion of a PM&S-24 leads to the foot surgery certification pathway of the American Board of Podiatric Surgery (ABPS) and the certification pathway of the American Board of Podiatric Orthopedics and Primary Podiatric Medicine (ABPOPPM). This program takes 24 36 months to complete
Podiatric Medicine & Surgery 36 (PM&S-36)
This model requires the same training as the 24 model but adds the component of reconstructive rearfoot and ankle surgery. Completion of a PM&S-36 leads to the foot surgery certification and reconstructive rearfoot and ankle surgery certification pathways of ABPS and the certification pathway of ABPOPPM. This program takes 36 48 months to complete.
For further descriptions of these training programs, see
http://www.cpme.org under Residencies/Standards, Requirement and Procedures for PM&S-24 and PM&S-36. Look within the CPME: 320 Document under Section 6.0.
Good luck! Scholl is a great program!
