The W. K. Kellogg Foundation provides several comprehensive tools to help organizations understand and undertake evaluations. A core tenet is that evaluation should not be simply an “add-on,” but should engage management in making mid-course corrections and document the success of its work. Kellogg's web site provides two tools that can be downloaded – the W.K. Kellogg Foundation Logic Model Development Guide and the W.K. Kellogg Foundation Evaluation Handbook. Both also are available in Spanish through this site.
