This article examines two aspects of evaluation planning for Extension programs: the use of program theory and logic models and the decision process that affects the evaluation's methodological rigor. First, Extension program planners should move beyond standard applications of logic modeling to incorporate a broader, more flexible use of program theory. Second, a highly rigorous evaluation will provide numerous benefits, but considering the costs that are typically required, an evaluation's degree of rigor should be carefully determined with reference to how the findings will be used. The article makes recommendations with the aim of promoting effective and economical Extension evaluations.
