In some states, only certain roles and responsibilities require certification. In some instances, you may need a Master’s degree in Library Science. Other states allow librarians to obtain a certificate or licensure to incorporate them into the library. For starters, it is recommended that you focus on programs that are accredited by the American Library Association (ALA). Not only do they generally meet the licensure requirements for a variety of librarian positions, but it also makes it easier to recertify if you are moving across different states.
