Institutions Reviewed: Includes all institutions on a given Commission meeting agenda. The number includes museums being reviewed by the Commission for the first time after a site visit and those submitting progress or final reports related to an earlier tabling decision. 

Accreditation Awarded: Institutions can be granted accreditation for the full 10 years or the museum can be flagged for an early review at 5 years.

Tabled: The Accreditation Commission “tables” its decision on a museum’s accreditation status when it identifies one or more specific concerns that are barriers to the institution’s ability to meet the Characteristics of Excellence, Accreditation standards, program requirements and/or eligibility, but which it anticipates can be addressed within one year or less.

Denied: Institutions are denied for failure to meet multiple Characteristics of Excellence and for major systemic problems. A denial decision can also be made when a tabled museum is unable to demonstrate adequate progress in addressing the Commission's concerns.

Deferral: The Commission may defer making one of the above decisions when it needs more information, clarification or expertise.

Other
: Institutions that did not receive a final decision during the meeting (i.e., were not awarded accreditation, tabled, or denied). These include museums only presenting progress reports as part of a tabling action.

About Success Rates
The Accreditation Program has an overall success rate of 97%. About 2% are denied outright and 1% are unsuccessful after being tabled. The success rate is high in part because there are many steps built into the review process for the museum to receive feedback and counsel from the Accreditation Program staff, Commission and site reviewers; the museum then has an opportunity to respond or take some type of action. Museums also receive counseling and support from the program staff before and during the process to ensure readiness. Most museums come into the process well prepared.

All accredited museums must go through reaccreditation every 10 years.

Tabling provides the Commission with an alternative to denial/withdrawal of accredited status so the museum can resolve very specific operational challenges in a focused and timely manner. Tabling is relatively common. Every year, approximately 30% of museums of all sizes and types have their decisions tabled.

Tabling is intended as a positive tool employed by the Commission for the benefit of the museum, rather than a negative decision. A tabling decision provides the impetus to immediately address weaknesses and can provide the leverage to secure resources and support to implement changes. A tabling decision is not punitive and is not an indicator of ultimate success or failure in the review process. Ninety-seven percent of all museums that have had their decisions tabled are awarded accreditation at the end of the tabling period.

1 This number includes several museum systems and museums with multiple sites, each counted as one accredited institution. Counting each museum within an accredited system increases the number to 1,057 museums. All demographic statistics are based on 802 accredited museums.
2 Two museums did not report staff size.
3 Based on 234 tabling reasons (a museum may be tabled for more than one reason). During this period, 90 museums were tabled.
