Which of the following factors most strongly indicates the effectiveness of training?

The effectiveness of training is best indicated by defined performance indicators that demonstrate improvement in job performance. When performance indicators are established and used to measure the outcome of training, they provide quantifiable evidence of how training has impacted an employee's capability to perform their job.

This improvement can be seen through various metrics such as increased productivity, enhanced quality of work, better customer satisfaction ratings, or higher sales numbers. These indicators are essential because they reflect the direct results of training initiatives, allowing organizations to assess whether the training content was relevant and effectively delivered.

Other factors, like employee attendance, while important, do not measure the actual impact of the training on job performance. Similarly, the duration of training programs or the number of resources used can provide some insights into the training process but do not necessarily correlate with improved job performance outcomes. Hence, relying on performance indicators provides a clearer picture of the training's true effectiveness.
