The aim of the "Train the trainer" course was to assist RMOs in the implementation of ISO/IEC 17025:2017 and its application to the CIPM MRA. It was organized as a follow-up to Resolution 3 of the 39th meeting of the Joint Committee of the Regional Metrology Organizations and the BIPM (JCRB). The Resolution states that "the RMOs shall ensure that all NMIs and DIs declaring CMCs within the CIPM MRA shall have demonstrated the conformance of their quality management systems to of ISO/IEC 17025:2017, no later than three years after the publication date of the standard".
