Edgar's revised classification (5)

I believe the answer is:

grade

'classification' is the definition.
(grade is a kind of classification)

'edgar's revised' is the wordplay.
'revised' is an anagram indicator.
'edgar' with letters rearranged gives 'GRADE'.

(Other definitions for grade that I've seen before include "Rank or status" , "Particular level of rank, quality, etc" , "School mark" , "one of the entertainment moguls" , "Degree" .)

I've seen this clue in the Evening Standard.
