the HHE Program and its legislative authority and a description of the program’s inputs, activities, and outputs. The committee’s evaluation of the HHE Program can be found in Chapters 3 and 4, which are organized in a manner consistent with the program’s logic model (presented in Chapter 2). In Chapter 3, the committee describes the relevance of the program’s strategic plan, its use of resources, program activities, outputs, and emergency response activities. The committee’s findings are organized and described under each of these categories. In Chapter 4, the committee evaluates the impact of the program. The chapter includes four sections corresponding to the four parts of the committee’s charge with respect to impact: (1) reduction in risk and prevention of occupational illness in investigated workplaces; (2) transfer of information beyond investigated worksites; (3) influence on NIOSH research and policy; and (4) impact on others in the occupational health community. A fifth section discusses the impact of program emergency response activities. Finally, in Chapter 5, the committee describes its vision of what the HHE Program of the future would be and summarizes recommendations made in Chapters 3 and 4.
