OSCE scoring and check lists

Check lists

OSCEs are marked on the basis of an examiner 'check list' and a 'global scoring' system. The check list is adapted for each OSCE case and will not stop you picking up 'points' by making other relevant observations.

Global scoring

You won't pass or fail on the basis of the check list alone, but rather it is a tool for the examiner to help determine the overall score. The good candidate will pick up a tick for every point along the way and arrive at a sensible conclusion relating to the OSCE scenario. If questions are asked these will be the same for every candidate. The examiner will make an overall assessment of competence and assign a grade as follows.

  • A - Mostly excellent
  • B - Mostly good
  • C - Mostly satisfactory
  • D - Mostly poor
  • E - Mostly unacceptable
  • F - Fail

If an examiner scores a candidate as E or F then he/she will have to state reasons for doing so.
