Pretoria - Apart from incidents of copying in KwaZulu-Natal and Eastern Cape, the 2014 matric exams were "fair and credible", monitoring body Umalusi said on Tuesday."We are satisfied that the examinations were fair and valid and credible. We commend the DBE (basic education department) for running a successful and credible examination process. Not perfect, but credible," Umalusi council chairman Prof John Volmink told reporters in Pretoria.Umalusi approved the release of the examination results, written by 550 127 full-time and 138 533 part-time candidates.He said results from 39 exam centres in KwaZulu-Natal and 19 in the Eastern Cape had been blocked after investigations showed there had been "group copying"."This is a new phenomenon... Umalusi is very concerned about this trend."He said the centres made up two percent of the total number in the two provinces and did not compromise the integrity of the examination."Umalusi is satisfied that nothing has compromised the integrity or credibility of the exams as a whole."He said action should be taken against the pupils and supervisors.On 25 November, the education department said matric results would be published in newspapers with only pupils' ID and exam numbers. The decision was made after a task team recommended that the practice of publishing pupils' names be reviewed.
