Kirkpatrick Four Levels
The standard model for evaluating training: Reaction, Learning, Behavior, Results. Each level is harder to measure and more valuable to know — most L&D functions stop at level 1 or 2, which is exactly why training budgets get cut.

When to use
- Designing evaluation BEFORE a training program launches (define level 4 first, work backwards)
- Justifying or defending an L&D budget with evidence
- Auditing an existing curriculum for programs that never get past smile sheets
When not to use
- When the intervention is not training (role design or incentives problems cannot be trained away)
- For informal/social learning where level isolation is artificial
- When no one will act on the results — measurement without decisions is theater
Worked example
A retailer invests in service training. Level 1: 4.5/5. Level 2: mystery-shop role-play scores up 25%. Level 3: 60 days later, only 30% of stores show the behaviors — investigation reveals store managers never reinforced them. Level 4 (NPS) unchanged. The Kirkpatrick chain locates the break: the problem is manager reinforcement, not course quality.
Common pitfalls
- Measuring only levels 1-2 and calling the program a success
- Deciding evaluation strategy after the program is built instead of before
- Claiming level 4 results without any control or baseline comparison
