Certified Emergency Nurse. The Certified Emergency Nurse (CEN) certification is specific to emergency nursing and measures the attainment of a defined body of nursing knowledge pertinent to that specialty. Currently, more than 34,000 nurses hold the CEN certification. Although there are CENs throughout the world, the CEN exam is based on emergency nursing practice in the United States.You must pass the exam to attain initial CEN certification.
To qualify for the exam, nurses must hold a current unrestricted Registered Nurse license in the United States or its Territories. A nursing certificate that is equivalent to a Registered Nurse in the United States is also acceptable. The Board of Certification for Emergency Nursing recommends 2 years’ experience in the emergency department; however, it is not required.
