The Nuclear Medicine Technology Certification Board, Inc. (NMTCB) was founded in 1977 to establish and maintain a voluntary program for certification of nuclear medicine technologists by nuclear medicine technologists. The standards established by the NMTCB include educational requirements, practical experience, and successful completion of an appropriate competency-based examination. The NMTCB certifies individuals whom have developed the requisite body of knowledge to practice nuclear medicine technology, and registers those individuals who meet these criteria.
