Assessment, which includes the setting and marking of examinations, is within the remit of the Scottish Qualifications Authority.I understand that an appeals procedure is in place to deal with any cases in which candidates fail to perform to their expected ability as set out in the estimated grades submitted for each candidate by centres. Results can be upgraded at two points in time. First there is an automatic appeal procedure carried out prior to the issue of results, where results will be adjusted if a centre's estimates of expected grades are generally accurate.
