Starting in 2022 proposals will be online, but the 2022 guidelines provides all the information that you will need to have on hand to fill out the form. This also provides information on writing a top-notch letter of support.
Check out the information here, including how to write the executive summary, what budgeting information is needed, what kinds of program items are supported, and ideas on methods and activities that have been successfully used at other schools.
As always, feel free to call Marty McIntyre for more information on writing a proposal.
