For CCRN, CCRN-E and CCRN-K certification candidates, March 25 is an important date: AACN will launch revised exams for these credentials, which align with updated certification test plans. The revised test plans and exams reflect minor changes identified in the 2018 study of acute/critical care nursing practice. Nurses testing on and after March 25 should reference the new test plans – and updated study resources – available now on AACN’s website.
