Small and Effective

… there are many non-profits who have made it out of the initial stages of growth, but haven’t made it to the level where rigorous impact evaluation is possible. These organizations have been around for a while, have somewhat sustainable funding sources, but are constantly looking for new funding to ease the financial tension that comes with being a small non-profit. For these organizations, small contributions can go a lot further than at larger organizations which aren’t as strapped for cash. It is also these small organizations that do not have the resources to prove their impact as well as the larger ones, or decide not to spend time on rigorous evaluation because it will disrupt the flow of services. Unfortunately, because of this, small organizations can usually only offer potential donors nice stories and smiling faces.
