Become a BSLS Member
BSLS membership connects students to a national community, mentorship, exclusive resources, leadership development, programming, and opportunities designed to support their academic, personal, and professional growth. Membership is valid for the 2026–2027 school year and is available exclusively to eligible students affiliated with an active or approved BSLS chapter.
Before You Pay
BSLS is a chapter-based organization. Membership is not open for general public enrollment. Students must attend a college, university, or high school with an active BSLS chapter and meet their chapter's membership requirements before submitting national membership dues.
Do not submit payment if BSLS is not currently established at your school. If you are interested in bringing BSLS to your campus, please complete the Charter a Chapter Application first. Membership dues should only be submitted after your chapter or membership eligibility has been confirmed.
