Logisk model er betegnelsen for et diagram med kasser og pile, der illustrerer programteorien / indsatsteorien / interventionsteorien - og fx er opdelt i ressourcer, aktiviteter, præstationer, virkninger og kontekst

Logisk model bruges i evalueringslitteratur og evalueringsrapporter om et diagram, der viser de centrale antagelser i programmet eller indsatsen.

Logiske modeller bruges som således som et redskab i programevalueringer eller teoribaserede evalueringer.

Begrebet er en direkte oversættelse af "logic model":

"Logic models have become a primary focus of evaluators in conceptualizing what is being evaluated"

(Michael Quinn Patton 2011, side 36 i fodnoten)

"a logic model is a systematic and visual way to present and share understanding of relationships among the resources you have to operate your program, the activities you plan, and the changes or results you hope to achieve” (W.K. Kellogg Foundation 2004, s. 1 - her fra Morten Eriksen den_logiske_model KREVI 2008.pdf )

"Evaluators use program logic models—flow diagrams that describe a program’s components and desired results—to explain the strategy—or logic—by which the program is expected to achieve its goals. By specifying a theory of program expectations at each step, a logic model or other representation can help evaluators articulate the assumptions and expectations of program managers and stakeholders. In turn, by specifying expectations, a model can help evaluators define measures of the program’s performance and progress toward its ultimate goals. (For examples, see GAO 2002.) 
 It is also important to identify the program’s stage of maturity. Is the program still under development, adapting to conditions on the ground, or is it a complete system of activities purposefully directed at achieving agreed-on goals and objectives? A program’s maturity affects the evaluator’s ability to describe its strategy and anticipate likely evaluation questions. 
At a minimum, a program logic model should outline the program’s inputs, activities or processes, outputs, and both short-term and long-term outcomes—that is, the ultimate social, environmental, or other benefits envisioned. Including short-term and intermediate outcomes helps identify precursors that may be more readily measured than ultimate benefits, which may take years to achieve. It is also important to include any external factors believed to have an important influence on—either to hinder or facilitate—program inputs, operations, or achievement of intended results. External factors can include the job market or other federal or nonfederal activities aimed at the same outcomes" (GAO 2012, side 10-11)
