If you do not mind, I would like to correct some of your statements.
Both ACFAS (American College of Foot and Ankle Surgeons) and ACFAOM (American College of Foot and Ankle Orthopedics and Medicine) do NOT administer any board certification examinations. These are organization that a DPM can join after attaining Board Qualification or Board Certification status with one of the certifying Podiatry boards. Upon graduating from the PM&S-24 or PM&S-36 residency program, residents become eligible to sit in one of the board certification examinations offered by board certifying organization such as ABPS (American Board of Podiatric Surgery), ABPOPPM (American Board of Podiatric Orthopedic and Primary Podiatric Medicine), etc... When a candidate passes the written exam for ABPS, the candidate can apply for the Associate status with ACFAS. When a candidate passes the written and oral exams for ABPS and gains board certification status, the candidate can apply for Fellow status with ACFAS. ACFAS only recognizes the ABPS board certification exam and not the other podiatric surgical board exams. If a candidate passes the written exam for ABPOPPM, the candidate can apply for Associate status for ACFAOM. If the candidate passes both the written and oral exams for ABPOPPM, the candidate can apply for Fellow status with ACFAOM. ACFAOM only recognizes the ABPOPPM board certification exam.
When a resident graduates from a PM&S-24 or PM&S-36, it does NOT automatically make the graduate Board Qualified. Graduating residents from one of those residency models (or older podiatric surgical residency models) would only make the graduate "eligible" to take the ABPS board certification exam. In order for a residency graduate to become Board Qualified, the graduate needs to pass the written portion of the ABPS board exam. When the Board Qualified candidate amasses sufficient enough of cases to submit and passes the oral portion of the ABPS board exam, he / she will become Board Certified.
Lastly, a residency graduate of PM&S-24 or PM&S-36 programs usually can do surgery based on the credentialling criterias at the hospital or surgery center without board certification. Many of the hospitals and surgery centers required the residency graduate to be at least Board Qualified status in order to do any surgery. Hence, many hospitals and surgery centers would require the graduate to pass the written portion of the board certification exam. Of course, there will be hospitals and surgery centers that do not require board qualification status to do surgery.
I hope that this will clarify some things.
