(A) Before a written competitive examination may be held to fill a current or expected vacancy in the ranks, the members eligible to take the examination must be notified of the written materials from which the questions will be taken. The Commission may employ instructors, purchase materials and make other expenditures to provide information for applicants for promotion examinations.
(B) The identity of a member taking the written examination shall be withheld from the person or persons grading the examination, and all written examinations are confidential. The Commission shall notify each member in writing of the score that the member received on the examination. The score received by a member on the written examination becomes a part of the permanent file of the member, and the member is entitled to access to this file for examination at any time.
(C) The examination papers shall be kept under the Commission’s supervision. A member who is aggrieved with the score received on the written examination may appeal to the Commission for review of the score. The appeal must be filed within ten days after notice of the score has been sent to him or her. He or she may review the questions incorrectly answered and challenge the answer considered correct by the examiner. The Commission shall either affirm the score or correct the score according to the findings of a review. The examination papers shall be retired after the two-year period during which the eligibility list is valid. The retired papers shall be kept for five years and then destroyed.
