The OCR exam board has apologised after some students in Northern Ireland failed to receive results on Thursday.
Pupils taking OCR Cambridge Technical qualifications have been affected by the delay.
The qualifications in subjects like Information Technology and Business are equivalent to A-Levels.
One parent of a pupil who failed to receive their grades told BBC News NI that his son had been "left in limbo" as a result.
The majority of pupils in Northern Ireland take A and AS-Levels through the Northern Ireland exams board, the Council for the Curriculum, Examinations and Assessment (CCEA).
