Appraisal or evaluation (6)
I believe the answer is:
review
This clue is a double definition.
'appraisal' is the first definition.
(I know that review is a type of appraisal)
'evaluation' is the second definition.
(I have seen 'Critical evaluation ' mean 'review' so perhaps 'evaluation' could also mean 'review')
(Other definitions for review that I've seen before include "A commentary by a critic" , "study" , "Retrospective survey" , "Critic's article" , "Look back on; periodical" .)
