In a CBE model, the curriculum is organized around specific competencies that students must achieve. These competencies are often outlined by professional nursing organizations and are based on best practices and evidence-based care. Instructors use a variety of assessment methods, including simulations, clinical practicums, and objective structured clinical examinations (OSCEs), to evaluate student performance. Students progress through the program by demonstrating proficiency in each competency, rather than simply completing a set number of hours or courses.
