I'm writing a grant proposal and I'm not sure how to include an appendix. Is it just an outline of the information that was included in the proposal?

No. See the following explanations of what an appendix is;

Including an appendix in a grant proposal is a common practice, as it allows you to provide additional supporting materials or detailed information that might be too lengthy or technical to include within the main body of the proposal. An appendix typically contains supplementary materials such as charts, graphs, financial statements, project timelines, resumes, or endorsements.

To include an appendix in your grant proposal, you should follow these steps:

1. Start by finalizing the content of your main proposal. Ensure that it presents a comprehensive and detailed explanation of your project or program.

2. Review the funding opportunity announcement or guidelines provided by the grantmaker. Some grantmakers might specify instructions regarding the format or content of the appendix, so make sure to adhere to any specific requirements mentioned.

3. Determine what supporting materials you want to include in the appendix. Consider items like budget worksheets, letters of support, curriculum vitae (CV) or resumes of key personnel, project timelines, sample surveys or questionnaires, organizational charts, or relevant data.

4. Organize the materials logically. You can include each item as a standalone document, or you can group similar items together in separate sections, using labels or dividers accordingly.

5. Number the pages of your appendix using a consistent format (e.g., A1, A2, A3, or Appendix 1, Appendix 2, Appendix 3, etc.) to differentiate them from the main proposal. This will help the reviewers easily locate specific items within the appendix if needed.

6. Create a table of contents (TOC) for your appendix. This TOC should list each item in the order they appear, along with a brief description or title for each item. Including a TOC helps reviewers navigate through your supplemental materials more easily.

7. Reference the appendix in your main proposal. Whenever you discuss a document or information found in the appendix, make sure to refer to it within the body of your proposal. For example, you might include a statement such as, "For more details, please refer to Appendix A: Project Budget."

8. Attach the appendix to your grant proposal. You can either bind it together with the main proposal or keep it separate but adjacent to the proposal itself.

Remember, the appendix should serve as a supporting resource and not as a replacement for a complete and well-written proposal. It should enhance the clarity and understanding of your project, providing additional relevant information to strengthen your case for funding.
