Presented here are the total number of certificates and the total number of currently valid certificates issued by the ABIM by discipline as of April 3, 2012. These data are updated annually. The “All Certificates" column identifies the total number of certificates issued, including certified internists/subspecialists known to be deceased and/or those whose certificates are no longer valid. The “Valid Certificates" column does not contain these groups. http://www.abim.org/certification

1. Candidates Certified - All Candidates
Presented here are the total number of certificates and the total number of currently valid
certificates issued by the ABIM by discipline as of April 3, 2012. These data are updated
annually.
The “All Certificates" column identifies the total number of certificates issued, including
certified internists/subspecialists known to be deceased and/or those whose certificates are
no longer valid. The “Valid Certificates" column does not contain these groups.
Candidates Certified by State:
All States and US Territories
State identification is based on the most recent address provided to the ABIM by the
physician. The ABIM has limited contact with some Board Certified physicians. Therefore,
the accuracy of many addresses is uncertain.
Candidates Certified by Country:
All Countries (Non-US)
Country identification is based on the most recent address (outside the United States)
provided to the ABIM by the physician. The ABIM has limited contact with some Board
Certified physicians. Therefore, the accuracy of many addresses is uncertain.
Because the ABIM does not have addresses for every candidate in its database, summing
the All States and US Territories data with the All Countries (Non-US) data may not produce
the Total data reported for All Certificates or the Total data reported for Valid Certificates.

3. ACGME Accredited Areas of Combined Training
Presented below are ABIM subspecialty certification data for ACGME accredited combined
training pathways as of April 3, 2012.
The “Single Disciplines” portion of the table presents data regarding the number of
physicians with a valid certificate in only one discipline within the combined training area.
The “Combined Disciplines” portion of the table presents data regarding the number of
physicians with valid certificates in both disciplines within the combined training area.
Because the ABIM does not have addresses for every candidate in its database, summing
the All States and US Territories data with the All Countries (Non-US) data may not produce
the Total data reported.
Please note that these data do not necessarily reflect the number of physicians practicing in
the disciplines listed.
