Undergraduate Member ($10.00)

Student membership is open to all engineering, math, physical, applied, and computer science majors. All others are invited to become associate members. Graduate students have the option to join SHPE either as a student or Professional Chapter. If you choose not to be affiliated with a chapter on your campus, you will be considered an “At-Large Member,” classified by your geographical region. Members “At-Large” receive the same benefits as those who belong to a chapter.

Scholarship applications are open http://scholarships.shpe.org. Most will accept students in any STEM field
