Are there any nursing schools or classes for male nursing that are available while still attending high school?

There are no differences in classes between "male" and "female" nurses, there are only Nurses and there is only Nursing School. Nursing school for RN's are 4 year programs in college like just about any major. LPN's may do it sooner but they are paid significantly less than RN's in many cases as RN's are deemed by states to have more qualifications to perform more duties and carry more responsibility. There are some science classes such as college chemistry and anatomy and such that you may get dual credit for college while in high school (check with colleges to see prerequisites for nursing schools so that you may fulfill some of them in high school as AP courses or whatever your high school provides). You may however take CNA (Certified Nurses Aide) classes at a career center/vocational school while in high school and work in a hospital as a nurses aid and get very good experience working in a healthcare setting as opposed to saying "I want to become a Nurse" while having no real idea of what that entails or what working in a hospital is like. I promise you, if you have never done it before, it is far different than you truly think it is at this point in your life. The armed forces have nursing programs as well, and they are quite good. Speak to your counselor about this and speak to an Army recruiter about this, they pay quite well and will pay for your school most likely. Good luck
