What approach should an NPD practitioner take when evaluating a training program's effectiveness?

The most effective approach for an NPD practitioner when evaluating a training program's effectiveness is to analyze pre and post-training assessments. This method provides a comprehensive view of the learning outcomes achieved by participants. By comparing the knowledge and skills of participants before and after the training, the practitioner can assess the specific impact of the training on learning and behavior changes.

Utilizing pre and post-training assessments allows for quantitative measurement of improvement and can highlight areas where participants have gained knowledge or skills. Moreover, this method aids in identifying gaps that may need further attention or additional training. It is a systematic approach that aligns well with evidence-based practice, enabling NPD practitioners to make informed decisions about the training's relevance and efficacy, as well as its alignment with organizational goals and needs.

In contrast, seeking feedback from participants alone might not provide a complete picture of the training's effectiveness, as personal perceptions may not reflect actual learning or performance improvements. Using observational methods exclusively may overlook the quantitative data that assessments provide, while focusing solely on completion rates does not measure the depth of learning achieved by participants. Therefore, analyzing pre and post-training assessments is the most robust and informative strategy for evaluating a training program's effectiveness.
