'creative students' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'shakespearean military officers' is the wordplay.
'shakespearean' becomes 'art' (I can't explain this - if you can you should give a lot more credence to this answer).
'military officers' becomes 'majors' (major is a kind of military officer).
'art'+'majors'='ART MAJORS'

'are' acts as a link.
