What type of test requires a worker to demonstrate work output?

The correct answer is work sampling, which is a method used to assess a worker's performance by evaluating their actual work output over a period of time. This technique involves observing a worker at random intervals and recording their performance, helping to create an accurate representation of productivity and efficiency in a specific role.

Work sampling is particularly valuable because it provides a practical measure of a worker's capabilities in real-time situations, rather than relying solely on theoretical knowledge or past performance. This direct measurement of output is essential for understanding productivity levels and identifying areas for improvement.

In contrast, time tests typically measure how quickly a worker can complete designated tasks, but they do not necessarily evaluate the quality or consistency of work output over a more extended period. Confidence tests focus on assessing a worker's self-belief regarding their abilities, not actual performance metrics. Lastly, aptitude tests gauge a worker's potential to perform specific tasks but do not evaluate their current work output. Each of these alternatives serves a different purpose and does not fulfill the requirement of demonstrating actual work output in the way that work sampling does.
