What tool is used to assess an individual's understanding of material in training?

The correct choice is Knowledge Check, as this tool is specifically designed to assess an individual's grasp of the training material. Knowledge Checks are typically integrated throughout the training process to help reinforce learning and ensure comprehension. They can take various forms, such as quizzes, interactive activities, or informal assessments, and are often used after critical lessons or modules to gauge understanding in a timely manner.

This immediate feedback mechanism allows instructors to identify areas where learners may struggle, enabling them to adjust their teaching strategies accordingly. By confirming that learners can recall and apply the information presented, Knowledge Checks play a vital role in the overall effectiveness of the training program.
