NA TIG Week: Using a Logic Model Framework to Plan an Evaluation by Sue Hamann

I’m Sue Hamann and have worked as an Evaluator for almost 40 years and am currently employed at the National Institutes of Health as a Health Scientist and Science Evaluation Officer. Many people new to evaluation are assigned to work as evaluators. My tips today are for those novice evaluators who need some help getting started with an evaluation plan.
Evaluators and many program staff are accustomed to summarizing programs or policies or other topics of evaluation with a graphic tool called a logic model. (I am going to just write “program evaluation” from now on, but it will mean any subject of an evaluation.)  A logic model describes the stage of development of a program. The columns in a logic model are typically labeled as follows:
Standard Program Logic Model Framework
(resources)(planned program components)(delivered and quantified programShort-termIntermediateLong-term
As an advocate for needs assessment as the starting point in program planning, I always modify the typical program logic model to show why a program is developed, as follows:
Comprehensive Program Logic Model Framework
Antecedent conditionsInputsActivitiesOutputsOutcomesOutcomesOutcomes
Evaluations must be tailored to the stage of the program.  For example, you cannot evaluate performance unless the program has been implemented and you cannot evaluate outcomes until the program has been up and running. These stages used to be known as the Evaluation Hierarchy and have more recently been termed Evaluation Domains. The domains differ by evaluation questions, types, and methods.

Lessons Learned:
  1. Adding Antecedent Conditions as the first column in your program logic model ensures that you understand why a program or policy was created and that you are focusing on relevant outcomes and impacts.
  2. The elements or columns in a logic model appear linear but are frequently iterative.
  3. The elements or columns in a logic model should be logically aligned.
  4. Developing the evaluation plan using a logic model framework can clarify your thinking and ensure that the evaluation is tailored to the stage of a program. Appropriate evaluation questions and methods differ depending on the stage of the program.

The American Evaluation Association is celebrating Needs Assessment (NA) TIG Week with our colleagues in the Needs Assessment Topical Interest Group. The contributions all this week to aea365 come from our NA TIG members. Do you have questions, concerns, kudos, or content to extend this aea365 contribution? Please add them in the comments section for this post on the aea365 webpage so that we may enrich our community of practice. Would you like to submit an aea365 Tip? Please send a note of interest to aea365@eval.org. aea365 is sponsored by the American Evaluation Association and provides a Tip-a-Day by and for evaluators.

About AEA

The American Evaluation Association is an international professional association and the largest in its field. Evaluation involves assessing the strengths and weaknesses of programs, policies, personnel, products and organizations to improve their effectiveness. AEA’s mission is to improve evaluation practices and methods worldwide, to increase evaluation use, promote evaluation as a profession and support the contribution of evaluation to the generation of theory and knowledge about effective human action.
