Does BTtoP allow supporting/supplemental materials for proposals and are these materials included in the page limit?

BTtoP does not encourage or expect supporting or supplemental documents. However, formal expressions of support, such as a letter from senior leadership (presidents, provosts, or deans), do indicate sustainability and the institution’s judgment of importance of the work. Such a document may be submitted along with your proposal should you deem it to be essential. A supporting document does not count toward the overall proposal page limit.Logic models and budgets can also be submitted as supplements if they are too large to fit within the 4 page guideline.
