Is it more sensible to enter an RN program vs a LPN in nursing since the LPN part time is 2 academic years?

If one is going straight from high school it is best to take all the health, science and math courses available and try to get into a RN program. There are still 2 and 3 year diploma programs but most hospitals are requiring a 4 year degree (BSN). Since there is a difference in skill, education, and ultimately state licensing required, I would recommend speaking with your high guidance counselor regarding an aptitude test or discuss your potential of getting into and succeeding in a 4 year degree program. There are a lot of scholarships and grants along with financial aid packages for nurses. Try private universities first, you may be surprised, they often have alumni who give back money specifically for nursing students who need it most!
Go for your RN, you'll be glad you did! I've met too many LPN's who've wished they started out in a RN program, first. But if you guidance counselor or tests reveal if best for you to take the LPN route first, then do that. After working a couple years(mostly nursing homes and some home health) you will have the confidence to go back and take what is required to then take you state board licensure exam for your RN license. All the best of luck to you!

I agree with Mary. If your goal is to become a nurse, start with nursing. Some colleges have "bridge" programs from LPN-RN, but they are rare in our area. This just lengthens the time it takes you to complete a degree in nursing. If you start as a freshman, you may qualify for more scholarships. Most four year colleges are trying to increase enrollment and offer better financial aid packages to freshman.
