Final answer:
Check rides during sustainment training can vary in frequency, with options ranging from monthly to biannually.
Step-by-step explanation:
In the context of sustainment training, a check ride is a practical evaluation of a trainee's skills and knowledge. It involves assessing their ability to perform tasks related to their training. The frequency of check rides varies depending on the organization and the specific training program.
In many cases, check rides are conducted annually or biannually. This means they are performed once a year or once every two years, respectively. However, some organizations may choose to conduct check rides quarterly (every three months) or even monthly.
The frequency of check rides is typically determined by factors such as the complexity of the training, the criticality of the skills being evaluated, and the need for ongoing assessment and improvement in the trainee's performance.
