HESI really will help you gauge how you’ll perform on the board exams. Detailed studies have been conducted on HESI exit exams, and research shows that the HESI exit exam is up to 99% predictive of NCLEX success. That means that if you succeed on the HESI exit exam, you’ll most likely pass the NCLEX.
Some schools also assign their own scores or passing requirements to HESI exams. Those course requirements are established by each school – not by HESI or Elsevier.
