Patricia Benner's research established the Novice to Expert model for skill acquisition in nursing. She categorized nurses into five levels - novice, advanced beginner, competent, proficient, and expert - based on their experience. As nurses gain experience over time in a clinical setting, they advance from relying mainly on rules to developing intuition. Benner's work provides a framework for understanding clinical competence and a guide for nursing education, mentorship programs, and career development.
