After a brief discussion of the terms implementation and monitoring, this article illustrates a strategy for monitoring program implementation. The strategy, called model-guided method, offers a way to develop conceptual and empirical specifications for testing the adequacy of a program implementation. It also provides feedback to program…

The use of theoretical models in impact assessment can heighten the power of experimental designs and compensate for some deficiencies of quasi-experimental designs. Theoretical models of implementation processes are examined, arguing that these processes are a major obstacle to fully effective programs. (Author/CM)

A broad conceptual framework is presented as a tool to guide researchers toward identification and development of variables in policy implementation studies. Concepts for developing variables to measure the "amount" of implementation and variables to identify the aspects of policy that need to be incorporated in a study are discussed.…

Evaluation research, if appropriately matched to a human service program's stage of development, can help inform the decision making at each step. The developmental stages of a program, questions to be answered at each stage, and kinds of research activities pertinent to such questions are discussed. (TJH)

Data from the Child and Adolescent Trial for Cardiovascular Health, a school-based field trial, are used to illustrate the use of process evaluation for understanding study outcomes. Teacher characteristics and fidelity to the program model had direct and independent effects on student outcomes from the program. (SLD)
