The HESI is used as a predictor for students who will pass the NCLEX. Say if you score a 900 on the HESI, you have a 90% chance of passing the NCLEX or if you score a 500, you have a 50% chance. The test is most definitely not used to make money. And it is true that it helps with pass rates, but for the student's benefit. The test breaks down your weak areas so you can see where you are lacking. It is up to the student how they will use the information. The HESI is based on the NCLEX test plan which is super helpful for NCLEX candidates. I was having difficulty passing the NCLEX and finally took a review class that broke down the areas where I was weak. My areas were OB and L&D. After I was able to see where I was lacking, I was able to focus on those areas, and I passed the NCLEX the next time. Trust me, you would be better off paying the $40 to take the HESI, than a repeat of the NCLEX that costs $200.
