Credits are available for technical sessions, short courses, and field trips. Ten contact hours are required for one CEU; for example, one day (8 hours) of technical sessions = 0.8 CEUs.

Student Travel Fund

Interested in helping students participate in the meeting?
Donate to the Student Travel Fund on your registration! Every year, a large percentage of students apply for travel grants but do not receive an award due to a limited number of funds. You can help increase the number of students helped by donating as little as US$10 via your registration form. 100% of the monies collected go to students.


GSA Sections, Divisions, and Associated Societies offer funding to help defray your costs for registration, field trips, travel, etc. Note: Eligibility criteria and deadline dates vary by grant. For meeting attendees who reside outside of North America, check the International Travel Grant webpage (deadline to apply: 5 July).
