The Society of Physics Students (SPS) is a national organization designed explicitly for students. Membership, through collegiate chapters, is open to anyone interested in physics.
From the national website: The SPS exists to help students transform themselves into contributing members of the professional community. Course work develops only one range of skills. Other skills needed to flourish professionally include effective communication and personal interactions, leadership experience, establishing a personal network of contacts, presenting scholarly work in professional meetings and journals, and outreach services to the campus and local communities.
