RJC Assurance System

The RJC assurance system acts to ensure that the requirements of the RJC standards are fulfilled by its members. Assurance is an essential part of our system as it enables us to demonstrate the credibility of RJC certification and the impact of the RJC standards.

The RJC Assessment Manual (click here to read about the new Assessment Manual 2018 requirements) sets out the overall structure of the assurance framework and contains instructions and guidance for members and auditors on how to conduct assessments to establish conformance with the RJC standards, including:

  • The process for achieving RJC certification;
  • How a member performs a self-assessment;
  • How auditors conduct independent third-party audits;
  • The principles for conducting effective assessments to drive continual improvement.


There are five main steps in the RJC certification process that every RJC commercial member must follow:


To maintain the credibility of its assurance system, the RJC utilises the following mechanisms:
