Abstract Submission Fee

There is a non-refundable abstract submission fee for the 2019 ACA Annual Meeting of $25 USD.  Completing your payment is necessary to submit your abstract. Your payment may be submitted electronically using a credit card on a safe and secure site. The abstract submission fee is not refundable, even if the abstract is not accepted. The abstract submission fee does not register you for the conference.


Abstracts for invited presentations must be submitted in the same manner as those for contributed papers but are not subject to the abstract fee.  A coupon code, to be used at the abstract checkout, will be forwarded to invited speakers.  If you are an invited speaker and have not received the coupon code please contact your session chair and/or ACA Headquarters for assistance.  It is imperative that invited speakers add their abstract to the cart, then use the coupon code and finalize, otherwise the abstract will not be submitted to the system.
