Competency testing can be conducted through various methods, including: 1. Written Exams: These tests assess theoretical knowledge on subjects such as pharmacology, anatomy, and patient care protocols. 2. Practical Exams: Simulation-based assessments where nurses demonstrate their skills in a controlled environment. 3. Observational Assessments: Evaluators observe nurses in their clinical settings to assess their performance in real-time. 4. Self-Assessments: Nurses evaluate their own competencies to identify strengths and areas for improvement. 5. Peer Reviews: Colleagues provide feedback on a nurse's performance.
