Mass. Gen. Laws ch. 112 § 255
A person who meets the qualifications to be admitted to the examination for licensure as a genetic counselor may, between the date of filing an application for licensure and the announcement of the results of the next succeeding examination, practice as a provisional licensed genetic counselor upon filing an approved application with the board and payment of a fee to be determined by the secretary of administration and finance. The board may grant a provisional license to a person who successfully completes a genetic counseling education program approved by the board and is qualified to be admitted to the examination. Such license shall be valid for 2 years from the date of its issue and may be renewed for an additional 2 years if an applicant fails the first sitting of the ABGC or ABMG certification exam. Such provisional license shall expire automatically upon the earliest of the following:
An application for extension shall be signed by a supervising licensed genetic counselor. A provisional licensed genetic counselor shall be under the general supervision of a licensed genetic counselor or a licensed physician with current ABMG certification in clinical genetics at all times during which the provisional licensed genetic counselor performs clinical genetic counseling. The board shall adopt rules governing such supervision and direction which may not require the immediate physical presence of the supervising licensed genetic counselor.
