To the student who posted a thread "Membership Confusion" - my apologies - it disappeared while I was trying to answer it.
See here https://www.accaglobal.com/us/en/help/student-faqs-practical-experience-requirements.html "completing 36 months' employment in an accounting or finance-related role or roles" is only ONE of three components of PER.
Also on the same page:
"Claiming your time
You only need to claim time when you leave a role or when you reach 36 months overall experience ..."
So you should claim you time. More importantly - while your supervisor is still in the company - you should get their sign off on the performance objectives that you have completed.
If you have any further questions that are not answered on ACCA's website you should contact ACCA directly via https://forms.accaglobal.com/contact-us
