You must hold a current RRT credential from the NBRC and have a minimum of one year (or equivalent hours) of direct, post-RRT clinical experience in adult critical care. The NBRC provides specific details on acceptable experience verification on their official website.

The computer-based exam consists of 150 multiple-choice questions, with 20 being unscored pretest items. You will have 3 hours to complete the test. The questions are primarily scenario-based, requiring application of knowledge to clinical situations.

The NBRC does not publish specific pass rates for the ACCS exam. It is scored using a criterion-referenced method, meaning your performance is measured against a set standard of competency, not against other test-takers. You will receive a scaled score, with a passing threshold set by the NBRC.
