I'm applying for a grant renewal. There are subtle and not-so-subtle differences between the solicitation document and the submission instructions document with regards to which materials (e.g. the proposal narrative, personal statement(s), CV(s), research schedule, budget, transcript(s) for student(s), etc.) are required for new proposals vs. renewal proposals.
Obviously, the best path would be to contact the funding agency to ask for clarification.
How might one proceed if contacting the funding agency to ask for clarification isn't an option?
Should I assume the solicitation as written overrules anything else? Would it be best to just include all materials mentioned in either document, or does it hurt to include "unsolicited" materials?
