Centralised arrangement for employment qualifications (11)
I believe the answer is:
credentials
'employment qualifications' is the definition.
'credentials' can be an answer for 'qualifications' (I've seen this before). I am not sure about the 'employment' bit.
'centralised arrangement' is the wordplay.
'arrangement' indicates anagramming the letters.
'centralised' is an anagram of 'CREDENTIALS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for credentials that I've seen before include "Qualifications" , "Ambassador's letter of introduction" , "Documentary evidence of competence" , "used for identification" .)
