Professional Accreditation

Accredited Conservator-Restorer (ACR) status demonstrates that a practitioner is a fully qualified and capable professional

The Professional Accreditation of Conservator-Restorers (PACR) is a professional qualification, administered by Icon. Achieving PACR demonstrates that a conservator shows a high degree of competence, sound judgement and an in-depth knowledge of the principles which underpin conservation practice.

The PACR Accreditation process, or framework, helps assess a conservator’s professional practice. It is applicable regardless of the route a potential ACR has taken in their career, their specialism or the context in which they practice. It is a key part of Continuing Professional Development. 

The PACR framework has three components:


  • An assessment process for accrediting professional capability against explicit standards  
  • A system for ensuring maintenance and enhancement of professional capability through Continuing Professional Development
  • A means of removing Accredited status from practitioners who fail to maintain a minimum standard of practice and ethics 

Employing an ACR

Accredited Conservators can be identified by the initials ACR after their name and the PACR Logo. 

Only Icon Associate Members can become Accredited. Application forms, guidance and examples can all be found in the members' area.
