Officials at the Swaffham Museum are celebrating after the London Street attraction’s quality accreditation was renewed for another three years.
The scheme, which is run by the Arts Council, assesses museums across England in three main areas.
One of the criteria is organisation, where managers must be able to show the museum is professionally managed and has clear strategic and financial plans for its future.
The scheme also assesses whether collections are properly catalogued, conserved and available to the public through displays, visits and other learning experiences.
User experiences, including the ability of visitors to give feedback on their visits and the response given by trustees, is the other main element of the scheme.
A spokesman said: “We are delighted to have been awarded certification of renewal of accreditation.”
The museum first received the award in 2013 and its renewal means trustees will be able to made applications for funding to a wide range of potential supporters.
