Public librarian professional certificates issued as of January 1, 2010 only remain valid when 60 hours of professional development are completed every five-year period. That means a deadline is approaching in about 7 months. Even if this doesn’t apply to you it may apply to staff in your library. Approved programs from accepted providers include formal classes or courses, workshops, seminars, lectures, institutes, webinars, e-courses, library conference programs, or other relevant programs. Curriculum that is pre-approved by the employing library can also fulfill the professional development requirement. Certificates or transcripts showing successful completion of courses are acceptable forms of documentation, as are letters from a supervisor indicating completion of a program or project.
