The debate meets the expectations of the assessment
The debate exceeds standards of the assessment.
One of the keys of debate is the structure of the argument. Is it easy to follow? Does it make sense to the audience? Is it long enough to make the point without going on too long?
How convincing is the argument? Has evidence and research been included or is the argument 100% opinion? Is the listener swayed by the argument?
Can the speaker respond to questions about the subject? How effective is their response?
