Appointment or promotion to the rank of Principal Librarian requires a documented record based upon three criteria specified in Section III. This includes a record of continued excellence in job performance and leadership in primary professional responsibilities (Section III A., Criterion 1), demonstrated excellence in one of the other two areas (Section III. B or C, Criterion 2 or 3) and very strong performance in the third. A pattern of significant contributions in these areas will be judged on how consistent, recent, and substantial the contributions and accomplishments have been.
Librarians appointed at the rank of Principal with continuing contract eligibility have a six-year probationary period. Librarians may be accorded up to two years of experience at a comparable research or academic library toward the six-year probationary period (Section III.A). A Principal Librarian who fails to qualify for continuing contract by the end of the probationary period will receive a terminal appointment.
