If you have looked at a nursing program that requires an admissions test, it is important to look at which test it is. Different nursing tests generally assess the same knowledge and skills, but certain programs may require more depth or subjects to assess their candidates. As a result, they will require the HESI over the TEAS. There may be an instance where your program of choice only requires the TEAS, but you are lacking course fulfillment in a subject that you can demonstrate your knowledge of on the HESI. Perhaps one program you are applying to requires the TEAS, but another one requires the HESI. Can the HESI be accepted in lieu of the TEAS in such instances? For more information, you will have to check with a program and its advisors for acceptable exceptions.
