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' is an anagram indicator.
'tread' anagrammed gives 'RATED'.
(Other definitions for rated that I've seen before include "Castigated" , "Censured" , "Estimated, set at" , "Taxed" , "Considered" .)
