Final answer:
The most effective method for evaluating training effectiveness is through the measurement of enhanced job performance, as this approach directly reflects real-world work outcomes and aligns with best practices in evaluating training impact.
Step-by-step explanation:
Evaluating Training Effectiveness
To evaluate training effectiveness, the most effective method is C. Measurement of enhanced job performance. A 2003 study by Arthur et al. highlighted that effective training can be assessed through various measures, including reactions, learning, behavior, and results. Measuring enhanced job performance directly reflects the impact of training on real-world outcomes, such as improvements in productivity and profits. This approach aligns with the fourth type of measurement according to Arthur et al. and captures not just immediate responses or mastery of content (grades in a training program), but actual changes in behavior and work outcomes. While discussions (whether in small or large groups) can provide valuable feedback and insights, they are generally less quantifiable and may not capture long-term training effectiveness comprehensively.
Evaluations that observe and measure the specific job activities a person performs and the results they yield are crucial for understanding how well a training program has translated into better job performance. This encompasses both quantitative aspects, such as productivity levels, and qualitative aspects, such as improved decision-making or efficiency.
