Those who claim to be teachers? (10)

Ross

I believe the answer is:

professors

I'm a little stuck... Click here to teach me more about this clue!

'teachers?' is the definition.
(I know this)

'those who claim' is the wordplay.
I cannot quite understand how this works, but
'claim' could be 'profess' (professing is a kind of claiming) and 'profess' is found within the answer.
The remaining letters 'ors' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'to be' is the link.
