Concept papers summarize projects or issues within an organization's interests and expertise. They provide in-depth discussion of a topic to obtain funding from donors. Concept papers outline the problem, goals, objectives, outcomes, evaluation methods, target population, and theoretical model of a proposed project. They may have developed from research or a previous project. Effective concept papers match the grantor's mission and funding priorities. They include an introduction, methodology, outputs/outcomes, team, and budget/timeline. The terms 'concept paper' and 'proposal' can be used interchangeably to request funding for a proposed initiative.
