The Audit Commission published the Comprehensive Performance Assessment (CPA) framework for 2006 in July. The culture service assessment for single tier and county councils for 2006 includes a performance indicator based on the levels of museums' accreditation.
The MLA's collections, archives development, workforce development and standards director, Gina Lane, welcomed the move.
'Museum accreditation, under its former name, registration, had been used as a best value performance indicator in the past but has been dropped for the past four years,' Ms Lane said.
'Its adoption as a CPA indicator is, therefore, very significant and a real achievement for the MLA.
'It will provide a level of protection to museum services at a time when many are under increasing financial pressure.'
Ms Lane said the indicator would apply to all single tier and county councils and would encompass many independent museums.
