It is reasonable for a candidate in a competition who invested considerable efforts in preparing for it to have an interest in knowing which errors he/she has committed. This interest is independent of the question whether or not the candidate decides to challenge his/her marks. However, by considering from the outset that a candidate's sole purpose in requesting such information is to challenge the marks, EPSO is merely reinforcing the candidate's conviction that the assessment was wrong and that the marks must be challenged. The Ombudsman considered that only the candidate concerned must assess the relevance of requesting details about the errors and non-errors identified in his written test. It is surely not for EPSO, before disclosing the requested information, to question the underlying reasons for such a request or whether it is reasonable to request the information.
