The survey of average wait times, while interesting and fun, is definitely not scientific. It only considers Facebook users who are members of certain groups on Facebook. Here are the wait times from the school itself:
November 2008 - 7 to 9 months
November 2009 - 7 to 9 months
October 2010 - 7 to 9 months
October 2011 - 3 to 5 months
September 2012 - 3 to 5 months
September 2014 - 6 months
I am only missing 2013 out of this set, but as you can see, it's not unusual for the wait times to ebb and flow.
Another consideration in the informal survey is that many students call a couple of times a day to secure a last-minute cancelation spot — that is truly the way to go if you are on fire to finish quickly!
Another item to mention: the reason that Excelsior has now instituted major changes to its acceptance policy is to limit the number of people enrolling. They no longer allow RTs or students who have completed a certain percentage of a traditional nursing program, they are requiring students to qualify via the TEAS exam, and they are requiring verification of student experience via a form signed by students' supervisors, and that form must be periodically resubmitted. I believe part of the increase in wait times is due to an increase in CPNE failures, and those students get back in line to test again and increase those numbers.
Best of luck with your educational goals! My advice, for what it's worth — ADN programs usually aren't too much longer than LPN, and then you can do an RN-to-BSN bridge while working if you desire. LPNs are very underutilized in some areas, so while it might be a faster path to licensure, it might not give you that experience you're seeking. But given that you have looked into this, I can imagine you have done your due diligence there as well.
