The HRPA Study Guide situates evaluation within a results-focused model (commonly framed in practice through reaction, learning, behaviour/transfer, and results). To show direct impact on organizational goals, data must at least evidence behavioural transfer (i.e., that learning is being applied on the job) and connect to operational metrics. Of the options given, measuring how long it took trainees to apply what they learned on the job captures a concrete transfer metric that can be linked to time-to-productivity, cycle time, error rates, or other organizational performance indicators—allowing the training function to argue causation or contribution to goals.

By contrast, confidence (B) and trainer performance (C) are reaction/learning indicators, and perceived supervisor support (D) is a transfer enabler rather than evidence of impact. HRPA competencies emphasize using post-training performance and transfer measures to demonstrate value and alignment with organizational outcomes.
