Items in the Master Item Pools (i.e., all NCLEX operational items) are reviewed on a continuous basis to ensure that they contain accurate content and reflect current entry-level nursing practice. In cases where there is an immediate change in nursing practice, such as changes in guidelines and policies, all items relevant to the topic in question will be reviewed to ensure that item content remains accurate. If necessary items can be pulled from the operational pool as needed to assure only current content remains on the exam.
