The ANCC Gerontological Nursing certification (GERO-BC) validates that registered nurses possess the clinical knowledge and judgment to care for older adults across acute, long-term, and community settings. The computer-based exam contains 150 questions — 125 scored and 25 unscored pretest items — and must be completed within 3 hours at a Prometric testing center. With 61.2 million Americans now aged 65 and older, representing 18% of the total population, board-certified gerontological nurses are in unprecedented demand. This guide breaks down every detail you need — eligibility requirements, content domains, study strategies, and exam-day logistics — so you can earn the GERO-BC credential on your first attempt.
