If you’re studying under AQ2016 and are due on your annual membership, you’ll just have to renew your annual membership as before.
However, if you’re are starting with the new AQ22, you need to pay a one-off registration fee for each specific level, which gives you the membership for its studying duration. Annual memberships are discontinued in AQ22.
If you are transferring to AQ22, you can just pay the one-off transitional fee (shown below) if you’re eligible.
Note: You still have to pay the assessment fees for each exam.
