NBCE Leadership Team

The National Board of Chiropractic Examiners (NBCE) leadership team is made up of Doctors of Chiropractic, statisticians, and business professionals in order to oversee the daily tasks required to develop, administer, and score standardized exams that assess knowledge, higher-level cognitive abilities and problem-solving in various basic science and clinical science subjects for candidates seeking chiropractic licensure.

The NBCE Parts I-IV exams offer assurance to the general public that, regardless of where a chiropractor went to school or was licensed, he or she has demonstrated a baseline of knowledge as well as ability in diagnosis, diagnostic imaging, principles of chiropractic, associated clinical sciences and chiropractic practice.
