if you are in rn school or going to be soon enrolling in rn school, then you either know about ati testing or soon will! i have been using ati at my school now for over year and with graduation coming soon in march we just took our first ati comprehensive predictor test! i searched online trying to find out information about this test prior to taking it - mainly how high of a score i would need to have my colleges requirement of a 90% predictability of passing the nclex, which is what my school requires for graduation. i had a hard time finding the information and what i did find i was not sure if it was corrrect. i wanted to share this information from my comprehensive predictor that i took! this will break down your score on the ati and then give you the equivalent or percentage rate of passing the nclex -rn the following information is based on the ati 2010 version column one is the rn comprehensive predictor individual score and column 2 is the predicted probability of passing the nclex-rn: 80.7%-100% = 99% 78.0%-80.0% =98% 74.7%-77.3% =96-97% 72.0%-74.0% = 94-95% 70.0%-71.3% = 91-93% 68.7%-69.3% = 89-90% 66.0%-68.0% = 84-88% 64.7% -65.3% = 81-82% 62.7%-64.0% = 75-79% i am stopping here as you can see that the individual scores are down in the low 60 % and you still have a 75% chance of passing the nclex-rn on your first try, however since most schools such as mine require a 90% probability of passing to graduate i didn't want to go on any further. if you need more information please let me know and i will continue the chart; when you take your first proctored comprehensive predictor you will get a chart on the last page of your report from the ati test, but i wanted to share this for those of you, who are like me and wanted information before going in to take the test! best of luck to all!
