Training _____ are official accounts of training events, presented verbally or in writing.

The term that appropriately fills the blank is "Reports." In the context of training, reports serve as formal accounts documenting training events, which can include details on what was taught, who participated, outcomes achieved, and assessments made. These reports are crucial for accountability, assessing the effectiveness of the training, and providing insights for future improvements.

While "Records" might seem like a logical choice, it typically refers to the storage of data or information about the training rather than a comprehensive summary intended for communication. "Outcomes" focuses on the results or impacts of the training rather than the documentation itself. Similarly, "Objectives" pertains to the goals set for the training rather than the actual log or summary of events that took place. Therefore, "Reports" is the most accurate term for documenting and conveying what occurred during training sessions.
