Michigan Compiled Laws, Chapter 380. School Code of 1976 § 380.1532

Sec. 1532. (1) Before a teaching certificate is valid in this state, the holder shall record the certificate in the office of the intermediate superintendent or of the superintendent of schools of the school district in which the holder expects to teach.

(2) Before a teaching certificate is valid in this state, the holder shall make and subscribe the following oath or affirmation:

“I do solemnly swear (or affirm) that I will support the constitution of the United States of America and the constitution of the state of Michigan and that I will faithfully discharge the duties of the office of teacher according to the best of my ability”.

(3) The oath set forth in subsection (2) shall be signed by the holder of the teaching certificate, notarized, and attached to or superimposed on the teaching certificate.

(4) Except as provided in this act, a teacher's teaching certificate shall not be nullified except by the state board and for a cause that would have initially justified the withholding of the certificate.

(5) Upon the request of a teacher, the state board immediately shall nullify that teacher's teaching certificate. Upon the request of a teacher, the state board may nullify 1 or more endorsements on the teaching certificate, or a grade level certification included in the teaching certificate, if the grade level certification or endorsement has not been used for 12 or more years.

(6) The state board shall not reinstate, reissue, or renew a teaching certificate, endorsement on a teaching certificate, or a grade level certification that has been nullified pursuant to subsection (5).
