Follow the directions. Most grant-making groups have formats and directions. They may have preferences on type size, line spacing, page numbers and margins. If you do not follow these guidelines, those making the decision may discard or return your proposal. Read the directions before, during and after you've written the proposal.
Most foundations are unfamiliar with educational terms and acronyms.
If you must use them, explain them clearly. Ask employees of the funding group to send endorsements. Send the proposal to several groups. Use the same proposal by changing the name of the group making the grant. Then send the proposal to organizations with similar funding philosophies.
