Missouri Revised Statutes Title XXII. Occupations and Professions § 327.271. Inactive license, requirements--return to active

1. A professional engineer licensed in this state may apply to the board for inactive license status on a form furnished by the board. Upon receipt of the completed inactive status application form and the board's determination that the license meets the requirements established by rule, the board shall declare the licensee inactive and shall place the licensee on an inactive status list. A person whose license is inactive shall not offer or practice professional engineering within this state, but may continue to use the title “professional engineer” or the initials “P.E.” after such person's name.

2. If a licensee is granted inactive status, the licensee may return to active status by notifying the board in advance of such intention, by paying appropriate fees as determined by the board, and by meeting all established requirements of the board including the demonstration of current knowledge, competency and skill in the practice of professional engineering as a condition of reactivation.

3. In the event an inactive licensee does not maintain a current license in any state for a five-year period immediately prior to requesting reactivation, that person may be required to take the principles and practice of engineering examination.
