Hybrid Component

We’re happy to announce that ACA2022 will be a hybrid conference experience, providing the option of participating in person or virtually.

The Meeting Committee and ACA staff have worked to curate a hybrid meeting space that is valuable and engaging for everyone, whether you attend remotely or in-person. We hope that all of you will be able to travel and meet us in Portland. However, for those who might not be able to travel, we would like to offer an opportunity to join us virtually.

Any session or event on the main program with a hybrid icon (pictured right) will be available to hybrid registrants.  The full list is outlined at the bottom of this page.  

We are entering a new era of meetings and travel in 2022, and we are looking forward to exploring a hybrid realm of “in-person” and “online” meetings. As ACA2022 is the ACA's first step into the hybrid world, we ask for patience with event organizers and staff. Please operate with kindness and understanding.


ACA2022 Hybrid Component FAQ

We know that “hybrid” can be interpreted in a variety of ways. Here’s the plan for ACA2022:

ACA2022 will blend an in-person (physical) event and a virtual (online) event, with select activities that allow in-person and virtual participants to engage with each other.

All registrants will have access to the ACA2022 virtual platform, website, and mobile app.

    • Keynote & Sessions: Access details will be sent to attendees closer to the meeting; an ACA profile will be required to access the attendee-only webpages. The events and sessions offered in the hybrid space are noted with the virtual icon on the program page.
    • Posters: All attendees will have access to the ACA2022 virtual poster gallery.
    • Contacts: All attendees will be have access to the sponsor, exhibitor, and attendee lists.
    • Sessions will take place live in Portland and be will be livestreamed via Zoom to the virtual audience. Virtual attendees will receive the list of sessions and join links via a private, attendee-only webpage shortly prior to the start of the conference, so they may join any live session rooms as they wish.  The virtual audience will be able to watch a session as it takes place in real time. During the Q&A period, virtual attendees will have the option to interact with presenters through the chat format in Zoom. A session chair or ACA volunteer will be moderating the session on behalf of the virtual attendees.

In-Person Experiences

Sessions will take place in the PDT zone in conference rooms at the Portland Downtown Marriott. Each room will be equipped with a podium, a laptop, a projector, a screen, and microphones. All in-person presenters must use the conference computer and wear the provided microphone. All attendees will be seated and will be able to see the presenter and ask questions during the designated Q&A period.


Virtual Experience

Presenters will be livestreamed from conference rooms at the Portland Downtown Marriott. Virtual registrants will have access to a private, password protected virtual meeting space with live join links. The sessions will be streamed LIVE as they take place in the PDT zone. Virtual registrants will be able to see the speaker on their screen in the Zoom platform and ask questions during the designated Q&A period via the chat app. There will be a moderator in the session room prompting virtual attendees and in-person speakers to ask questions and discuss.


What time zone will the conference take place?

All sessions and events will be held and broadcast in Pacific Daylight Time (PDT).


What are the technical requirements my computer will need to attend the livestreamed sessions?

To have the best possible virtual experience, be sure you’re accessing the virtual conference with a strong internet connection. If others are using the same internet connection as you, you may need a stronger bandwidth. Contact your internet provider to determine your individual internet needs for the best experience or ask others not to use the same internet connection as you while you’re participating in the live virtual event. You may also wish to view detailed system requirements or to test your system prior to the virtual conference


What do I need to know about Zoom?

If you are unable to or do not wish to install Zoom on your computer, you can join the webinars from a web browser instead. If you haven’t used Zoom before, click the link to download Zoom prior to the day of the meeting and familiarize yourself with any features you may need to use during a session or event (mute/unmute microphone, stop/start video, etc.). Please ensure that you have the most up to date version of Zoom to maximize the quality of your experience at the meeting.


Who do I contact for questions during the virtual event?

Our team will be available to answer questions, assist, and optimize your experience throughout ACA2022. Detailed information on contact information will be provided prior to the launch of the conference.



The session will be livestreamed and recorded. At this point we have not determined if/how/when the recordings will be shared, but we will keep you updated.


Copying/Rebroadcasting/Sharing of Information/Talks/Slides/Posters, etc.

By registering and participating in this event, you have agreed that you acknowledge and understand that screen-capturing, recording, or attempting to copy and/or distribute any ACA Virtual Meeting content, including but not limited to print, video, or live talks are strictly prohibited.
