'just procedural' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'choice between academic and master' is the wordplay.
'choice between' becomes 'for' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'academic' becomes 'ma'.
'and' says to put letters next to each other.
'master' becomes 'pro' (I've seen this in another clue).
'for'+'ma'='forma'
'forma' after 'pro' is 'PROFORMA'.

'is' acts as a link.
