i can only offer you my opinion; this is a question that will yield many answers/suggestions.
i began my rn-msn search about 2 1/2 years ago, and like you wished to "skip" the bsn portion as i had been a nurse for over 10 years with much success in my respective fields. as such, there was little a bsn could offer me that i hadn't already accomplished. after extensive research i narrowed my decision to chamberlain and excelsior, ultimately enrolling in excelsior college. i chose excelsior based on the curriculum, rollingenrollments, lack of gre requirement (which was essential for me) and interaction with advising staff prior to enrollment. i officially enrolled july 2010 and will be graduating from both programs next month (july 2012) with a 4.0 gpa.
the classes are typically 15 weeks, with a few consisting of 8 week intervals. for asn or diploma prepared rns, there is also the opportunity to test out of several bsn "fundamental" courses as well as prerequisites that may be lacked. this saved me much time as i tested out of 4 bsn classes and the humanities prereq i lacked. classes require a weekly post (short essay supported by research) with at least 1 or 2 responses to your peers’ posts. there are no midterms or final exams, replaced instead by research papers typically of your choosing within a given generalized category (example: ethics, theory...). typical course load per semester is two classes; however, i averaged three with a couple semesters of four courses (one of which was always only 8 weeks in duration). it should be mentioned that i stopped work to become a full time student and have no obligations outside of a somewhat self reliant husband whose job requires extensive travel. i found the classes not only engaging but also relevant to the healthcare arena in general. nearing completion, i also feel confident in my education and overall leadership abilities.
the advising staff was always readily available and helpful in an encouraging and positive way. excelsior is not "pushy" nor do they employ a sales department. when i made initial contact for advising purposes i was able to send over unofficial transcripts for review and essentially better guidance. as a result, there were no surprises in my overall course requirements. excelsior is not only 100% on-line with any campus time required; they are also cognizant of various times zones with the advising offices open late on mondays and wednesdays to accommodate. all advising sessions were always followed with an email summarizes the questions and recommendations.
i cannot speak of enrollment fess or tuition costs as i utilized my husband's gi bill. however, from what i have heard (heresy) excelsior’s fees are substantially less than most academic institutions. excelsior does have some difficulties with initial rn credibility within certain state boards, but there seems to be no difficulties with rn's seeking employment with advanced or bridge program educations.
overall i have been very happy with my academic journey and would honestly recommend excelsior college. if they offered a dnp program i would in all honesty continue my educational journey within their domain. i hope this helps.
