I'd also look into the number of candidates sent to take NCLEX. Some schools may have 100% pass rate but with fewer number of candidates. For example, Trinity College had 9 candidates who took NCLEX but with 100% pass rate. Now contrast that with Loyola University with 208 candidates with a 93% pass rate --> Illinois Center for Nursing.
Just curious, where did you get your data regarding NCLEX pass rate? According to the Illinois Center for Nursing Devry Chamberlain in 2010 shows a 97% pass rate. Of 36 candidates, 35 passed. While Purdue University in Calumet is showing a 92%. It doesn't show the number of candidates though --> Indiana Center for Nursing.
Other factors to consider:
1. Flexibility of schedule
2. Clinical sites
3. Academic Probation Policy (i.e., if you fail, how many chances do you get to repeat a course.)
4. Remediation process
5. Grievance Process
7. Transfer of credits policy
8. Other services (tutoring, mentoring, job assistance)
