Which role would be most responsible for keeping a record of attendance and performance?

The role most responsible for keeping a record of attendance and performance is typically designated as S-1 within a JROTC framework. The S-1, or Personnel Officer, is primarily focused on managing personnel records, which includes maintaining accurate records related to cadet attendance, academic performance, and any other pertinent information regarding the members of the unit. This position is essential for ensuring that all information related to cadets is organized and easily accessible for reporting and administrative purposes.

In contrast, other roles such as S-2 deal with security and intelligence, S-3 focuses on operations and training, and S-4 is responsible for logistics and supply. Their functions, while crucial to the overall operation of the JROTC unit, do not specifically involve the tracking of attendance and performance. Thus, the S-1 position is specifically aligned with these responsibilities.
