The certification process for CCRN-P involves meeting specific eligibility requirements and passing a rigorous examination. The American Association of Critical-Care Nurses (AACN) administers the CCRN-P exam. Eligibility usually requires a minimum number of hours of direct clinical practice in a pediatric critical care setting within the last two years. Once eligibility is confirmed, nurses can register for and take the CCRN-P exam, which tests their knowledge and skills in pediatric critical care.
