I would say that a good share (if not all) of nurses chose their educational paths based on their life situations and abilities to complete a particular program.
I started in LPN school because the ADN and BSN programs had waiting lists a mile long. Then I got my ADN, now in a BSN program.
But that's not the best way to go about it, IMHO, if you are in a position financially and otherwise to go straight through a BSN program from the start.
When you take the career ladder approach like I did, you will end up being in school a lot longer and possibly be paying for more tuition, fees and books depending on employer reimbursements.
Like another poster pointed out, LPN programs are a full time year minimum if not longer, yet the majority, if not all ADN and BSN programs only give one semester of advanced placement credit for LPN's.
So the LPN to RN student ends up taking a lot more coursework meaning more time and money than the straight through ADN or BSN student.
In my BSN program, many of us had to complete a considerable amount of prereq's before actually starting the program. So even though you can complete a BSN in 4 semesters while working full time as an RN, many are still completing chemistry, statistics, world religions, or whatever wasn't required of them in their ADN programs. Hence, more school, more money, more time.
If you are in a position to complete a BSN right off the bat as your basic nursing education, go for it.
The longer you wait, school only gets more expensive as tuition at most schools increase just about every year, and the older you get, the more complicated your life gets in terms of fitting school into the picture.
