You can find a number of sample proposals at the links below if you would like to see how some other colleges and universities frame their proposals. Please note that all proposals are different. Proposals to a federal agency will be very different than one to a private local foundation. The best place to find a sample proposal that works for you is to look on the organization’s website to which you are applying for funds.
