Discuss the differences among the varying types of evaluation

Answer 1

Formative evaluation helps to pinpoint and eliminate any kinks in the proposed delivery system or intervention before the program is fully implemented. For example, formative evaluation can be used to assess educational materials.
Process evaluation involves examining program activities in terms of the demographic variables of the target population; the program's organizations, funding, and staffing; and its location and timing. Process evaluation focuses on program activities rather than on outcomes, and it occurs throughout the planning and implementation phases.
Impact evaluation is used to determine whether and to what extent a program or an intervention accomplished its stated goals. It describes the specific effect of program activities on the target population and on immediate indicators of a program's success.
Outcome, or summative, evaluation determines whether the program or intervention had an effect on the target population's health status, food intake, morbidity, mortality, or other outcomes. Outcome evaluation tends to occur at the end of the program or intervention.
Structure evaluation includes assessing the personnel and environmental factors related to program delivery.
Fiscal evaluation determines how program outcomes compare with their costs either through a cost-benefit analysis or a cost-effectiveness analysis.
