The document discusses reasons for joining the Society of Women Engineers (SWE) based on historical documents and a recent survey of members. It finds that traditionally, SWE provided professional networking and mentoring that particularly benefited women in male-dominated engineering fields. A key reason students originally joined was to find support from other women, while professionals often cited desires to support other female engineers and students. Currently, SWE aims to promote gender equality and opportunities for women in engineering through career resources and outreach.
