Score, working with new examiner (6)
I believe the answer is:
censor
'examiner' is the definition.
'score working with new' is the wordplay.
'working with' indicates anagramming the letters (working with the letters).
'new' becomes 'n'.
'score' with its letters mixed up with 'n' makes 'CENSOR'.
(Other definitions for censor that I've seen before include "Official with power to prohibit distribution of material" , "Remove offensive parts" , "Person authorised to remove unacceptable passages" , "Suppress (information)" , "One vetting films, etc" .)
