Most of the colleges are full for 2004. I was accepted into the Nashua Tech this year for their 2004 nursing program, but decided not to attend there, but Rivier instead. They only had 16 spots available at first, and 1 week after I got a rejection letter, I got a phone call saying they had approval for 16 more spots, but these would have to be evening students. Since I already had my acceptance for Rivier also, it took me a while to decide (especially the difference in tuition!), but ultimately I got a nice scholarship from Rivier and really wanted a day program, which they offered me.
But to answer your question, most of the colleges, especially the community tech's, don't have waiting lists. You need to re-apply each year, though the Nashua tech (which is a sister school with Claremont) said they would put me on the waiting list for their Keene program, which is just getting off the ground. I've been attending NHTI in Concord for over 2 years, and applied twice. They are very hard to get into, and want ALL of your pre-requisite courses done before you apply. Pretty stingy.
It's amazing that all of tech college, even though related, have different requirements for admission. My NLN scores were not high enough to get into Manchester this year, but NHTI, Nashua and Rivier thought they were fine. Go figure.
It's frustrating, but my advice, having gone through it several times, is to apply EVERYWHERE. I also decided if I didn't get into a program this year, I would apply to LPN programs and even go to the Red Cross to get my CNA. I also was going to apply to the Surgical Technician program in Concord, but ultimately didn't because I did get my acceptances.
Good luck to you! Don't give up!
