CCRN certification is a specialty certification for nurses who provide direct care to acutely/critically ill adult,pediatric or neonatal patients and their families. These patients may be found in such units as: intensive care,cardiac care, combined ICU/CCU, medical/surgical ICU,trauma unit or critical care transport/flight. The CCRN exam is based on a study of practice, also known as a job analysis. The job analysis, conducted at least every five years, validates the knowledge, skills and abilities required for safe and effective practice as an RN or APRN who provides direct care to acutely/critically ill patients in one of the following patient populations:adult, pediatric or neonatal. The test plan, which provides an outline of exam content,is developed by an expert CCRN panel based on the results of the study of practice. The organizing frame-work for all AACN Certification Corporation exams is the AACN Synergy Model for Patient Care.
