Arts Council runs the accreditation scheme for museums. The Accreditation Scheme sets out nationally-agreed standards, which inspire the confidence of the public and funding and governing bodies. It enables museums to assess their current performance, as well as supporting them to plan and develop their services.
Initially, museums need to complete an eligibility questionnaire and send it to Arts Council. Once this is approved, the museum will be regarded as Working Towards Accreditation. Then the museum has up to 3 years to complete the policies and procedures required for the full accreditation. The Accreditation Advisor and your Museum Development officer can help you with the whole process.
