Are medical physicists who were board certified, State licensed, or State approved prior to April 28, 1999, exempt from having to meet the new requirements regarding their degree, semester hours of physics, and training on conducting surveys? What about survey experience?

No. All medical physicists, including those who were board certified, State licensed, or State approved prior to April 28, 1999, must meet the new requirements of either 900.12(a)(3)(i) initial qualifications or 900.12(a)(3)(ii) alternative initial qualifications regarding their degree, semester hours of physics, training on conducting surveys, and initial survey experience. There was no blanket "grand-parenting" of medical physicists who qualified prior to April 28, 1999.
