ImpactMatters (now Charity Navigator)

ImpactMatters has been acquired by Charity Navigator (charitynavigator.org). American donors report caring strongly about impact. Yet no major nonprofit rater assesses results. ImpactMatters is filling this gap with a new rating system that rewards nonprofits that are highly impactful. To issue ratings, we gather information published by the nonprofit, calculate its cost-effectiveness and assign a star rating.
