Non-members are welcome to attend ASO conferences.
If you apply for membership later, credits earned 18 months prior to your acceptance as a member may be applied toward your education requirements. However, the ASO maintains records only for its members, so it is your responsibility to keep track of your credits.
Your CER form is your proof of credits earned and must be picked up at the end of the conference. If you are unable to arrange your travel plans to remain until the forms are available, please give someone else authority to retrieve them for you.
