I did not attend Oakton, but I wanted to let you know about the NLN exam. It is a service that many schools
use for testing, to weed out candidates. What you need to get into the school depends on how many people apply. In Illinois, and probably other states too, the school must have no more than 10 students per clinical instructor. If your school has 6 instructors per semester, it can only handle 60 new students at a time. If 250 students apply for admission into the program, they must weed out 190 students.
Scores and composite scores are meaningless for the most part. What they do is compare your scores electronically with 20,000 other scores for that period, around the entire US. Then you get ranked into a percentile. You have a percentile for the science, math and verbal sections. Schools look at the overall percentile ranking. If it comes down to a tie for the last slot available, they will look at the individual percentiles (probably focusing on the science portion of the score). They will also look at completed coursework and grades in a tie situation. Percentiles are tabulated and should be on the sheet you receive back from the NLN testing people.
Someone that is prepared for nursing school
will probably score over an 80th percentile. Most nursing schools take something around, (just under or over), the 90th percentile these days. They also do not take people from out-of-district. Most of the people that went to my school when I started scored between 90th percentile and 95th percentile, however some scored higher. I managed a 99th percentile, which by the way is the highest possible ranking. I still missed 3 or 4 in science, 6 to 8 in math I think and about 11 in the verbal sections. But overall, it was ranked a 99th percentile.
