@BostonStudentNurse: Just curious, where are your clinical placements? How far along in your ABSN are you?
The ABSN students at my shcool seem to get the same clinical opportunities that the traditional and DENP students get (same locations/instructors). I have had students in my cohort complain about their placements, and most of the time giving this feedback to the school gets them moved to a different clinical site (provided it isn't just a personal preference issue). I have also witnessed or heard reports of some instructors that don't do many med admins with first semester (MS-1) students and some that allow quite a bit of independence. This is almost totally resolved by senior practicum.
Also, I found that one of my best clinics was NOT a major Boston hospital and one of my least favorite (and most restrictive) WAS a major Boston hospital.
As far as selecting a program, look at the NCLEX pass rates (on MA Board of Nursing site) for different schools
/programs during your school choice. There are some "cheaper" school with great pass rates and some "pricey" schools with marginal rates. Also, talk to students currently enrolled, they often will dish about any drama in programs.
