Where rules vary
United Kingdom regulated qualification (Ofqual accreditation 603/1273/7), available across the UK nations; the handbook notes centres adapt statutory/professional-body references for delivery 'in nations other than England', but there is a single assessment specification, not nation-specific exam variants.
