Batch of qualifications isn't cleared - chaos (11)
I believe the answer is:
credentials
'batch of qualifications' is the definition.
'credentials' can be an answer for 'qualifications' (I've seen this before). I'm unsure of the 'batch of' bit.
'isn't cleared chaos' is the wordplay.
'chaos' indicates anagramming the letters.
'isnt'+'cleared'='isntcleared'
'isntcleared' is an anagram of 'CREDENTIALS'.
Can you help me to learn more?
(Other definitions for credentials that I've seen before include "Documentary evidence of competence" , "Ambassador's letter of introduction" , "Qualifications" , "used for identification" .)
