First of all one must say thanks to the internet, those who would normally have educational options closed to them due to the time involved now have new options to consider. It is now possible to get an online nursing degree without ever stepping into a classroom, from a Licensed Practical Nurse (LPN) all the way up to a Doctor of Nursing Practice. The overwhelming convenience of having classes available 24 hours a day and 7 days a week is a powerful draw, as is the ability to move as slowly or as quickly through the course as necessary to match your learning needs.
There is a big shortage of nurses today all over the country and all sorts of establishments are looking for people to fill positions. Programs have been developed to deal with that shortage, including accelerated online nursing degree programs that are used to get nurses out into the workforce as quickly as possible. These often require the student to already have a bachelor degree, but an RN is not required - that will come once the course is done. This is a great option for those who don't want to, or are unable to, take full time classes.
