Membership and certification are different
Board Certification (BCSI) is a professional credential, not a membership level. It indicates graduation from an IASI Recognized Basic Training, passing the Certification Exam for Structural Integration (CESI), and ongoing recertification through continuing education.
A member may hold BCSI in addition to Professional or Professional Plus membership. Certification demonstrates competency; membership expresses participation in the professional community.
