What can be created to track who needs training and the timing of that training?

The ability to track who needs training and the timing of that training is best accomplished through the use of listings. Listings can effectively organize relevant data regarding training requirements, including employee names, available training sessions, and deadlines for completion. This organized format allows for easy identification of individuals who require training and helps in managing when they will receive that training.

Reports can summarize various data, but they usually do not create a straightforward mechanism for ongoing tracking. Schedules might lay out timeframes for training but can lack the detailed personal tracking needed to pinpoint who specifically requires training. Diaries serve more as personal journals or logs and would not provide the structured overview necessary for training management. Thus, listings are the optimal choice to meet the needs outlined in the question.
