Funding at UW is often administered through specific departments. It is important to be in contact with your program to know if they have funding for graduate students and information about applying to these opportunities.
Teaching Assistantships (TA), Research Assistantships (RA), and Graduate Staff Assistantships (GSA) are administered by individual departments, and are often are not widely publicized. Some positions are only open to students in particular programs, though many assistantship positions are open to any graduate student at UW (including Bothell and Tacoma students). The Graduate School Office of Fellowships, Assistantships, and Awards provides more in-depth information about the specifics of these positions.

In addition to any funding available from your department, there are two major sources for conference travel available from UW. If you are presenting at a national or international conference, these opportunities will help fund your travel and often have a quick application process. Be mindful of narrow application windows (dependent on the dates of your conference) for these funding opportunities!
If you are not presenting at the conference you hope to attend, see if the national level or your local chapter of the sponsoring organization offers a "first time attendee" or "professional development" scholarship. Many professional and academic conferences often discounted student rates, and some may waive registration fees partially or in full if you commit to a few hours of volunteering at the conference.
