A standardized checklist shall be used for all such interviews, but such checklist shall not constitute a grading sheet or evaluation form for use in the ultimate decision of qualification of the provisional appointee as a public health officer.
Copies of the results of each interview shall be supplied to the provisional officer within two weeks following each such interview.
Following the third such interview, the secretary shall evaluate the provisional local health officer's in-service performance and shall notify such officer by certified mail of his or her decision whether or not to qualify such officer as a local public health officer. Such notice shall be mailed at least sixty days prior to the third anniversary date of provisional appointment.
