I wouldn’t be so sure of that. The actual passing score for the exam is zero (it’s essentially pass/fail), and, for example, over 96% of test takers in NH pass:

First Time NCLEX Pass Rates and Schools
According to the NCSBN, the national first time NCLEX-RN pass rate for US educated nurses in 2020 was 86.5% and the PN pass rate for the same period of time was 83%. The pass rate for repeat RN test-takers was only 42.9% and for PN 35.6%. The NCSBN publishes annual and quarterly NCLEX pass rates on a state level, if you’re interested in seeing how your school stacks up. Regardless of your school’s pass rate, remember that your ability to properly prepare for and pass the NCLEX is 100% in your own hands.
Some nursing schools do not graduate the students who do not pass. So the school has a 100% pass rate. Example I know a school that took in 90 students annually but routinely graduated about 54. Excellent nurses but they were all put through a wringer.
Along with the students who were expelled They would routinely evaluate school tests and inform students that they were not graduating. The students had the option of staying another semester. Then taking the state retest.
Those were the days when the exams were taken in civic centers over two days at long tables of 4 with 200 nurse-lngs and a ton of proctors.
