The evaluation guides are a series of evaluation technical assistance tools developed by the CDC Division for Heart Disease and Stroke Prevention (DHDSP) for use by state and local health departments. The guides clarify approaches to and methods of evaluation, provide examples specific to the scope and purpose of health departments, and recommend resources for additional reading. The guides are intended to offer guidance and a consistent definition of terms. The guides are also intended to aid in skill building on a wide range of general evaluation topics while recognizing that health departments differ widely in their experience with, and resources for, program evaluation.
