Final answer:
A general discharge under honourable conditions signifies a service member's performance was satisfactory, between good and average, but not exemplary.
Step-by-step explanation:
The performance of a person who receives a general discharge under honourable conditions is typically not characterized as excellent. Such a discharge suggests that the service member's performance was satisfactory but may have involved some aspect of their conduct or performance that did not meet all of the military's highest standards. This rating tends to fall between good and average, but closer to the good side of the spectrum than poor or excellent. It indicates that while the individual did not display exemplary conduct or performance, they also did not display entirely negative qualities that would warrant a dishonourable or bad conduct discharge.
