" Eligibility Requirements
A BSN is NOT required to sit for the CCRN exam.
Applicants must hold current, unencumbered registered nurse licensure in the United States. In order to meet the RN licensure requirement for initial CCRN certification and recertification, an individual nurse's RN license must be unencumbered. This means that an RN license, issued by a state board of nursing, must not have provisions or conditions that would limit the nurse's practice in any way. It is the responsibility of the exam applicant or CCRN-certified nurse to notify the AACN Certification Corporation when any restriction is placed on his / her RN license.
CLINICAL PRACTICE ELIGIBILITY
Critical care practice as a registered nurse is required for 1,750 hours in direct bedside care of (adult, neonatal or pediatric) acutely or critically ill patients during the 2-year period preceding date of application, with 875 of those hours accrued in the most recent year preceding application. All 1,750 hours must be in care of same patient population (for example, for the adult CCRN exam, all 1,750 hours must be caring for acutely/critically ill adult patients). Clinical practice hours accrued in an undergraduate student role are NOT acceptable. Nurses serving as manager, educator (in-service or academic), CNS or preceptor may now apply their hours spent supervising nursing students or nurses at the bedside. Nurses in these roles must be actively involved in caring for patients at the bedside; for example, demonstrating how to measure pulmonary artery pressures or supervising a new employee or student nurse performing a procedure. "
to summarize if you are an RN with a clean license and you worked 1750 hours as a bedside nurse in a critical unit you qualify to write the CCRN exam. the process of studying for the exam is more the challenge. the increase of your knowledge will improve your ability to care for really sick pt's. i wrote the CCRN exam after 2 years in crit care, i am a very good test taker, and as i walked out of the exam i was convinced i had failed it because it was the hardest exam i had ever taken. i had passed it. the next challange was to plan out my recert in 3 years because i was never taking that exam again ! and that is where the true knowledge of the CCRN's come out.
My advice to you is study hard and take the exam and ignore the nay sayers !!!
