In October 1988, the ABEM initiated a policy of time-limited certification. A program of maintaining certification has since been established to provide a mechanism for ABEM Diplomates to demonstrate their continuing education in electrodiagnostic medicine, as they keep up-to-date with changes in this medical specialty. Diplomates are expected to demonstrate current medical knowledge and clinical problem-solving skills in periodic maintenance examinations.

The ultimate purpose of maintaining certification is to reassure the public and the medical profession that after initial certification, ABEM Diplomates continue to assimilate new knowledge and techniques and continue to develop their clinical skills. The Maintenance of Certification Program (MOCP) sets high standards for quality medical care and demonstrates professional accountability to the public by the ABEM and its Diplomates. The program is designed as a 10-year period of documenting continuing education in electrodiagnostic medicine, culminating in a half-day, proctored maintenance examination.

Time-limited certificates were first issued to Diplomates in 1994, and are current for 10 years. To maintain Board certification, Diplomates from 1994 onward must successfully complete the MOCP. Diplomates certified prior to 1994 may participate in the program on a voluntary basis and must follow the process outlined in the MOCP. However, Diplomates certified prior to 1994 will not lose their Diplomate status if they withdraw from the program or are unsuccessful on the examination.
