Regarding your questions, please check my comments in GREEN
1. Reference letter from employer is mandatory?
If yes, My current employer is not ready to provide is there any other document I can attach?
- As per my understanding you must need letter from your employer. you may submit you job duties letter you might have prepared for PR process. But i suggest you better ask CIPS people about what else is accepable.
2. For WES, I want to send my report directly to CIPS, is there any specific location we need to mention while raising WES upgrate?
- yes, the address is already mentioned in the certification form.
3. Once WES and application report is ready,
we need to email application for certification or its all online?
- Please email them all your documents, i suggest you with a proper subject line.
I have tried to answer all your questions as per my knowledge.
Thanks
