4.6 Avoid comments related to character unless you know the individual well. The receiver may be making notes that will be subject to the same rules as written references. It is College policy to use a disclaimer but do not rely on it to protect you. You must rely on honest, accurate, information provided with due care to all parties. 4.9 If you have any doubts about including information it may be best to leave it out.
Omission is probably less damaging than potentially false information.
If you receive pre-printed reference forms, complete them if you are content to answer all the questions asked. If this is not possible, it is normally acceptable to provide the reference by letter. 5.2 Interview panels are advised to consider references in good faith and document the Panel's opinion on whether the references are satisfactory or unsatisfactory. It is not the College's practice to offer appointments 'subject to reference'.
