The Building Evaluation Capacity (BEC) program was initiated in the fall of 2006 by the Hartford Foundation for Public Giving's Nonprofit Support Program (NSP). It was designed to give participating organizations the knowledge, skills and tools to evaluate, improve and communicate about their work. The Class of 2015 is the fourth group of Hartford‐area nonprofit organizations to participate. BEC is a multi‐year program that includes evaluation capacity development for selected organizations and ongoing study for participating organizations that have completed the initial evaluation capacity building work. The evaluation capacity building training operates in two phases (phase I = initial training and evaluation project design, phase II = project implementation and continued training). Each phase is designed to provide comprehensive, long‐term training and coaching to increase both evaluation capacity and organization‐wide use of evaluative thinking for participating organizations.
