ESA offers discounted membership rates for students, who receive all of the benefits of regular members, including discounts for books journals, discounted Annual Meeting registration rates, access to the ESA Membership Directory, and access to the ESA journal archives dating back to the early 1900s.
To qualify for discounted Student membership rates, you must be currently attending classes at least 1/2 time at some point during the membership year (i.e. if you start the year as a student and subsequently graduate, you will continue as a Student Member for the duration of that year and can renew the following year as a Student Transition Member).
