Just like the other schools that use the NLN test, in Illinois, there is a maximum ratio of teachers to students. This is required at clinical sites. That ratio is 10 students maximum to one instructor. A particular school will need to weed out a number of students that exceeds their limit each semester. They do this fairly by using the nationally recognized NLN exam. they do not know the score required until they compare the percentile rankings, but they use those rankings to sort out the students. Percentile ranking requirement could actually go down if there is a drop in enrollment.
Someone else pointed out in/out of district. They are right. It has gotten so tough to get into a local school that community colleges have restrectided admission to county residents. I know of one guy that worked in Lake County, and he chose CLC because it was near his work, but he was denied enrollment in the program because he lived in another district.
If a student is in district, however there is a tie for the last slot, lets say at 91 percentile, they look at academics. That is, they compare grades and other course completion for the tie breaker.
In these programs, they also expect the student to be doing all the leg work. If you get accepted, be sure to check your requirements continuously with the nursing department. If you get through part of the program and are missing something like part of your health check or currency in CPR certification in the right program, you will be dropped from the program.
If you get into the program and you do not qualify for financial aid, you may be able to get scholorships. They are not too hard to get. Nurisng is expensive. Plan to spend $800 + on books. You will be buying a decent stethoscope and/or other items as time goes along. Flash cards can be helpful and I like the Mosby's nursing drug reference book. The 2010 one is quite good. I like the one for Iphone (on skyscape), but the paper one will do just fine. And be prepared for expenses for graduation, pinning, NCLEX registration, photos and other school requirements to finish. Its not cheap!
The programs are tough to get into, because if you aren't willing to put in extra effort, someone else will. Good Luck.
