Please note: Our meetings take place in public convention centers, which means that while we strive to create an inclusive and accessible environment, there are inherent limitations to the extent of control we have over the overall setting. We encourage attendees to make accommodation requests during the registration process and in doing so, every effort will be made to fulfill reasonable accommodations. We also, but more so, cannot guarantee accommodations for requests made on the day of the event.

Description of Community Attendee Category

To ensure inclusivity and accessibility, this reduced-rate opportunity is specifically tailored for individuals who are not involved in research or academic roles who indicate a financial need and who have not submitted an abstract as a presenting author for the current INSAR conference. Instead, this category welcomes family members of autistic individuals and autistic adults who are not affiliated with INSAR as members, previous members, or prospects. Registrants will self-identify for this category. Availability is limited to ensure a widespread benefit.

All selected registration categories are subject to review for accuracy. Registration Accuracy and Member Type Policy: Failure to register with the correct member/attendee type will result in the cancellation of your registration and a refund of fees paid (less any applicable cancellation fees). Please ensure accuracy during the registration process to avoid delays.
