All candidates require two references; one academic, and one relevant experience. The Clearing House website provides detailed information on this question at https://www.leeds.ac.uk/chpccp/references.html.
This includes guidance on choosing who to ask to provide your reference, and advice including a factsheet and guide for those providing the reference. It may be helpful to review this information, and if appropriate, share with your indicated referees so that they are able to assess whether they are able to speak to the points contained within.
Please note the following guidance as per the Clearing House:
1. Academic references should, where possible, be from an academic institution where the person applying has studied. The academic referee should have direct experience of the applicant’s academic performance (i.e. competence in academic performance, academic study / scholarship, and research experience / performance).
2. Relevant experience referees should have direct experience of, and be able to comment on, the applicant’s performance in a relevant clinical context (and/or research context if appropriate). The experience reference should be from the applicant’s current employer where possible. Applicants may choose to use a previous employer as their experience referee if there is a good reason, e.g. they are not currently working in a relevant role, or have only worked in their current role for a few months, or their current employer can only provide a standard HR reference. However, candidates must explain why they are not using their current employer as their experience referee in the Personal Statements section of their application.
