Not all "use" looks the same — and knowing the difference changes how you evaluate
Introduction
Topic 28's third stage — "Using the Evaluation" — covered the procedural mechanics: considering recommendations, drawing up an implementation plan, disseminating findings. This topic goes one level deeper, asking a more conceptual question: when evaluation findings genuinely get "used," what does that actually look like? The answer, drawn from one of the most influential frameworks in evaluation studies, is that use takes several distinct forms — and conflating them leads to unfair judgements about whether an evaluation "succeeded."
๐ฏ Learning Outcomes
- Explain Carol Weiss's three types of evaluation use: instrumental, conceptual, and symbolic/political.
- Explain Michael Quinn Patton's addition of "process use" as a fourth type.
- Recognise why an evaluation can be genuinely useful even without directly triggering an immediate decision.
- Identify symbolic use honestly, as a documented empirical reality rather than simply evaluation "failure."
๐ Why This Matters
Carol Weiss's research on evaluation use found that policymakers rarely make a single, identifiable decision directly traceable to one evaluation report; more often, evaluation findings accumulate gradually alongside other information, subtly shaping how people understand a problem over time — a phenomenon she termed "enlightenment," which is very different from the simple picture of "evaluation report leads directly to decision."
1. Weiss's Three Types of Evaluation Use
Instrumental Use
Findings directly inform a specific, identifiable decision or action — for example, discontinuing a training method that evaluation showed to be ineffective, or revising next season's curriculum based on Topic 27's Results-level findings.
Conceptual Use
Findings shape how people understand a programme or problem more deeply, without necessarily triggering any immediate, identifiable action — contributing to the kind of "lessons learned" that Topic 28's evaluation report format explicitly makes space for.
Symbolic (Political) Use
Findings are marshalled to justify, legitimise, or defend a position or decision that was, in effect, already made — using evaluation as supporting evidence for an existing stance rather than as a genuinely open inquiry.
2. Patton's Addition: Process Use
Michael Quinn Patton (1997), building on Weiss's typology, identified a fourth type distinct from the findings themselves: process use — where simply going through the act of being evaluated changes how people think or behave, independent of what the final findings actually say. A KVK's Subject Matter Specialists reflecting carefully on their own training objectives while helping design an evaluation's questions may already shift their practice before a single piece of data is collected.
| Type of Use | What Triggers It | When It's Recognisable |
|---|---|---|
| Instrumental | The findings themselves | A specific, traceable decision or action follows |
| Conceptual | The findings themselves | Understanding shifts, but no single action is directly traceable |
| Symbolic/Political | The findings themselves | Findings are cited to support a pre-existing position |
| Process | Participating in the evaluation itself | Changes appear before, or independent of, the findings being released |
⚠️ Symbolic Use Is Not Automatically Dishonest
It is tempting to treat symbolic use as evaluation gone wrong — findings twisted to serve a predetermined agenda. Weiss's own research treats it more evenhandedly: symbolic use is a well-documented, common empirical pattern, not necessarily evidence of bad faith. An organisation genuinely committed to a programme may cite supportive evaluation findings to defend continued funding, which is a legitimate use of evidence even though it did not originate the decision.
3. Why This Matters for How You Design an Evaluation
If Topic 28's Terms of Reference clarifies upfront which kind of use is actually intended, the evaluation can be designed accordingly: an evaluation meant to drive instrumental use needs clear, decision-relevant recommendations delivered on a timeline that matches an actual decision point; one aimed primarily at conceptual use can afford to be more exploratory and reflective; and recognising the likelihood of symbolic use should push evaluators toward extra rigour, since findings may end up cited well beyond their original, narrower purpose.
๐พ Extension Angle
A KVK's mid-season evaluation of a farmer training programme might produce instrumental use (immediately dropping an underperforming training method), conceptual use (Subject Matter Specialists gaining a better general sense of which topics farmers find hardest to grasp, informing programming well beyond this one programme), and process use (the act of interviewing farmers for the evaluation itself prompting SMS staff to reconsider their own assumptions about farmer needs) — all from the very same evaluation exercise.
๐ฎ๐ณ Indian Institutional Context
ATMA's evaluation and reporting cycle (Topics 22 and 28) plausibly generates all four types of use at once: instrumental use when a district reallocates its budget toward better-performing activities; conceptual use as district officials build a broader understanding of farmer needs over successive reporting cycles; and symbolic use when positive evaluation findings are cited to justify continued state or central funding for the ATMA scheme itself.
๐ Beyond Agriculture
Corporate training evaluation is a common site of symbolic use: positive Kirkpatrick-level findings (Topic 27) are frequently cited in budget review meetings to defend an L&D department's continued funding, regardless of whether those specific findings were what originally motivated the programme's design — a corporate parallel to the ATMA example above.
