Quality Certificates

Resolution JCRB/45-1 (March 2022)

The JCRB noted that the RMOs have progressed successfully with a mix of in-person, online and hybrid periodic reviews of quality management systems of the institutes in their regions. The JCRB encouraged the RMOs to further develop these review routes and keep to the 5-year review period. Exceptionally, where this is not possible, they may extend the validity of these QMSs subject to a case-by-case evaluation by the RMO concerned. This extension of validity shall be for a period not exceeding one year. The power to grant such extensions will be re-evaluated at the time of the 46th meeting of the JCRB.

[Note that the 46th meeting of the JCRB will likely be scheduled for March 2023]
