How about this for a remarkable piece of writing, from a proposal we reviewed recently:
Detailed biographical details are included in CV’s in Appendix C and in Tables 3a, 3b, 4a, 4b, 4b, and 5 and in Appendix G.
Our esteemed colleague Richard Jenkins described one recent proposal as suffering from ‘Appendix-itis’. Sure, there are times when material needs to be moved to an Appendix – most often, if its length would disrupt the flow of your story.
But this should be the exception, rather than the rule – a last resort to be carefully justified each time. And, at the very least, the main answer should include a synopsis of the material that the evaluators would find were they to read the Appendix – ensuring that you get the maximum score whilst recognising that reviewers probably won’t read the detail on their first pass through.
