Evaluated tread badly (5)
I believe the answer is:
rated
'evaluated' is the definition.
(rating is a kind of evaluating)
'tread badly' is the wordplay.
'badly' indicates anagramming the letters (letters in the wrong order).
'tread' anagrammed gives 'RATED'.
(Other definitions for rated that I've seen before include "Castigated" , "Censured" , "Estimated, set at" , "Taxed" , "Considered" .)
