Librarian Certification

In order to ensure that communities are served by qualified library personnel, the MBLC grants Professional and Subprofessional Certificates of Librarianship to applicants based on work experience or education level, as set forth in statue (MGL c.78 s.22-31) and regulation (605 CMR 3.01-3.06).

The certificates are required of all Massachusetts public library directors for eligibility in the State Aid to Public Libraries Program.

Basic Library Techniques (BLT)

Upon application, the MBLC issues certificates for the completion of the Basic Library Techniques (BLT). The BLT is a group of four special training courses designed for public library directors who do not have a Master of Library Science degree. The intent of the BLT program is to provide practical training in library administration, reference, cataloging, and materials selection.

The BLT requirement to receive state aid applies only to municipalities with a population under 10,000, and within that group, only to library directors who do not have a Master of Library Science degree.

Sign up for notifications about the BLT class schedule with the Massachusetts Library System (MLS).


The current fees are $53.00 for a Professional or Subprofessional certificate and $38.00 for a replacement certificate.

Regulations call for certification fee review every three years. Fees are established by vote of the Board of Library Commissioners. At its July 9, 2015 meeting, the board voted to increase the certification fees to $53.00 and the replacement fee to $38.00.
