The SIS Master of Library and Information Studies program has been re-accredited for another seven years by the American Library Association in January 2010. The decision to grant continued accreditation to the program was based on the “totality of the accomplishment and the environment for learning…”
SIS's MLIS program has received continued accreditation since 1927/28.
On ALA accreditation:
"ALA accreditation indicates that the program has undergone an external review and meets the ALA Committee on Accreditation’s Standards for Accreditation of Master’s Programs in Library and Information Studies."
"Accreditation is a voluntary system of evaluation of higher education institutions and programs. It is a collegial process based on self-evaluation and peer-assessment for improvement of academic quality and public accountability. Accreditation assures that higher education institutions and their units, schools, or programs meet appropriate standards of quality and integrity."
"Accreditation is both a process and a condition. The process entails the assessment of educational quality and the continued enhancement of educational operations through the development and validation of standards. The condition provides a credential to the public-at-large indicating that an institution and/or its programs have accepted and are fulfilling their commitment to educational quality."
