Chair, this question relates to the moving up of matric results. There has not been any modification of results in the past 15 years. But based on current legislation and in keeping with international practice, marks of specific subjects get adjusted during a standardisation process which is conducted by an independent quality assurance council - Umalusi.
Research shows that despite all the best initiatives taken by the examination body to ensure that exams conducted in a specific year are of the appropriate standard is never possible to guarantee that an examination in a particular year is of the same standard as an exam in the previous year. Therefore, to ensure that a candidate writing exams is not subjected to a more difficult or much easier exam, marks obtained in a current examination are compared to the performance of candidates in the previous year. If marks of a cohort are comparable to the previous year, the marks are accepted. But if the marks are too high or too low, there's a normal standardised adjustment process that gets implemented. So, nothing unique is done; we are told that this is international practice.
