There's a gap between funders' perspectives on how much they support indirect costs ("overhead") and organisational development, and NGOs' perspectives on just how much funders are willing to support it.

This research along with our assessment guide and tips can support NGOs and funders in this important work. [For the assessment guide, "Organisational Development Assessment Guide," see ED622362. For the tips, "Tips for Grant Pitches: Know Your Funder's Mindset," see ED622361.]
