Goal-free evaluation (GFE) is an evaluation approach where the evaluator conducts the evaluation without knowledge of the program's stated goals and objectives. The GFE evaluator attempts to observe all actual outcomes of the program, intended or unintended, in order to determine what the program actually does without reference to what it intends to do. GFE has benefits such as reducing bias, uncovering unintended effects, and aligning goals with actual outcomes, but criticisms include the risk of missing important effects and lack of guidance for implementation.
