CNS trains officials in NS in the practices and methodologies determined by Cheer Canada. Officials are required to take the Cheer Canada Officials exams for the disciplines in which they judge. Cheer Canada does not train nor test officials in IASF Legality training; this is only managed by the IASF/USASF.
Officials may also be certified in other disciplines such as the Unified Scoresheets, Varsity, and/or ICU.
