CA: Noun or Adjective

When you wanna use it after your name, you can mention it as ACA (Associate Chartered Accountant) or FCA (Fellow Chartered Accountant) as may be applicable. 

ACA in my case, yes.
thank you so much for your response Vaishnavi

Please note, ACA can be used only incase the person is qualified Chartered Accountant and is holding a Certificate of Membership from ICAI

Well, now there arises a doubt in my mind. A person who pays membership fees but doesn't intend to take a COP for the entire lifetime.

should they be using CA as an adjective or ACA ?

my concern is I believe I will have CFA charter holder a couple of years down the line which should strictly be used as adjective as per CFA institute guidelines. Wondering how will CA fit in the name.

Hope you got my point ?

when you are not going to get COP for lifetime, then you continue to remain as ACA.
