Meet the assessors

Assessors are the face of the accreditation programme, acting as ambassadors and upholding its reputation. Assessors support IQAS by promoting and championing good practice and continuous improvement. They have a critical role in assessing services for accreditation, providing a fair, comprehensive and transparent assessment and providing clear instruction for service improvement. Our assessors are consultants and nurses in the service and we also have lay assessors, who represent the patient voice. If you are interested in applying for the role of assessor, please email the team to express an interest:
