All unit standards and qualifications are supposed to be reviewed at three-year intervals. This is to keep the standards up to date with progress made in the industry. Reviews are made by a working group of stakeholders under the guidance of the relevant SGB. Anyone can call for a review if (s)he feels that a standard or qualification is inappropriate, in need of updating or just plain wrong. The request should be made through the SGB and should supply adequate motivation for change. A word of warning: some of the standards published on the SAQA database are incorrect for various reasons, so any changes desired must be routed through the SGB with a request for an initial check on the correctness or otherwise of the published standard, before extensive drafting of changes is done.
