Survey revealing deception: sect’s up for reform (10)
I believe the answer is:
conspectus
'survey' is the definition.
(thesaurus)
'deception sect's up for reform' is the wordplay.
'deception' becomes 'con' (I've seen this before).
'for reform' indicates an anagram (I've seen this in other clues).
'sects'+'up'='sectsup'
'sectsup' is an anagram of 'spectus'.
'con'+'spectus'='CONSPECTUS'
'revealing' is the link.
(Other definitions for conspectus that I've seen before include "Summary, overview" , "Overview (of subject)" , "brief" .)
