Roxxy,
I'll try to answer your questions on Stratham. The answers may apply for Manchester as well because the two programs just split a year ago. Until then you could move back and forth without a transfer application, but they are now two distinct programs. I don't know much about the other programs around here.
A&P I&II took the whole summer. We started the last week of May and finished around the second or third week of August. It was intense. The summer program is taught by a professor with a fierce reputation. He's a little bit 'old-school', but I feel like I really learned the material, so I'm not going to knock him. The class met 3 times a week, from 8:00 - 1:15. This time included both lecture and lab. As I recall it basically worked out to be a test every two weeks and they were tough. I'm glad I did it. The program requires you to get at least a 'C' in A&P I&II concurrent with (or prior to) Nursing I&II. If you don't get the 'C' then you can't continue on with Nursing. Then you have to wait a year for the right class to come along before you can re-enter, and then you are dependent on a space being open. That's another reason I liked having it out of the way. I didn't need that stress.
The clinicals have mostly been close to Stratham. Dover, Portsmouth, Exeter, and Brentwood. The only locations far away have been for the psych rotation. Some students ended up an hour away. But you only do psych for a half-semester, so that shouldn't be too big a problem for most.
I'll give my opinion of the program, but of course it is biased and I'm naive about the competition. The faculty in Stratham is very dedicated and involved in our development. Most of the teachers are very good. There are a few who are less dynamic. The clinical sites that I've been to have been excellent; they welcome students and go out of their way to provide interesting opportunities. I think that I've been fortunate; I'm not sure that all of the clinical sites (particularly first semester extended care facilities) have been too exciting for everyone. Then again, students who are already LNAs have already 'been there, done that', and may be bored stiff with the first semester clinical.
Outside of the nursing program things are a little different. Stratham is definitely a 'junior' college. If you are smart enough to get into the nursing program, you'll feel like a rocket scientist in the GenEd classes. Test out of as many as you can! Do it for your sanity!
Finally, it is my understanding that the Stratham program has a 100% pass rate on the board tests for graduates in the past two years. I think that demonstrates that the program is focusing on the right subjects and presenting it clearly. Some people might judge that they are teaching to the test, but I personally feel like that's appropriate in a field where you need to be licensed.
My experience in Stratham has been a positive one. I'd recommend it to my friends.
I hope this helps. And remember, 'your mileage may vary.'
