This paper describes the Rhode Island Tobacco Control Enhancement Project (TCEP), a state-university-community technical assistance system. TCEP was developed under the auspices of the Rhode Island Department of Health's Tobacco Control program and was designed to build capacity among nine community-based organizations to mount comprehensive tobacco control interventions in five diverse communities within the state. This paper: (1) provides a description of community mobilization ; (2) presents a logic model for planning and decision making used by state-university-community partners; (3) describes training, technical assistance services and implementation; and, (4) describes the evaluation and program improvement activities used to support on-going project development.
