The OSCEs use standardised clinical scenarios, which ensure every candidate receives an equal and fair evaluation of their knowledge and skills. The pass mark for the Primary OSCE is currently set using a modified Angoff reference method. The OSCE is about overall performance and candidates do not have to pass a predetermined number of stations. Each question is assigned an Angoff score, which has been determined before the examination by an Angoff group of OSCE examiner experts. Angoff scores for each question are aggregated to give the examination pass mark.
