The National Association of Boards of Pharmacy just released the 2015 North American Pharmacist Licensure Examination (NAPLEX) passing rates for pharmacy schools in the United States.

In 2014, 9 US-based pharmacy schools saw 100% of its students pass the NAPLEX on their first attempt. This year, however, significantly fewer schools achieved the same accomplishment.

Only 2 schools saw 100% of their students pass the test on their first try, but 3 other schools weren’t far off, with around 99% of their students passing.

Here are the top 5 schools with the strongest NAPLEX passing rates.

(Note: One school that is not on this list, Lebanese American University, achieved a 100% passing rate, but since it is not located in the United States and 2 students took the exam, it is not included here. However, Lebanese American University is an accredited American University; it operates under a charter from the state of New York.)
