Nursing is a great career with many options and pathways. If he can get the ADN/RN while he is in high school, via a community college while in high school program, he definitely should. It’s worth two years of college and probably 15-20K in tuition and fees to him. I’m assuming that he will be 18 yrs old before he is graduated from high school? And that he would be able to finish the ADN/RN by the time he is graduated from high school? Then he absolutely should do that, and at the same time should be investigating the transfer to a 4 yr college’s shortened ADN/RN to BSN program. He should plan on working as an ADN/RN for at least a semester, and maybe a year, before he enters the shortened ADN/RN to BSN program.
He will miss out on the college experience of making lots of friends while living at college as a freshman. That’s both good and bad - there’s a lot of bad behavior that goes on, sometimes with tragic consequences. But he’ll be able to earn a good living from right after high school, and a better living two years after that, and possibly a great living by the time that he’s about 23. Contrast that to the traditional 4 yr BSN starting at age 18, plus a couple of years of work, and then the NP or DNP program, which all would put him done by about 25-26 at the earliest.
Look into his getting his CNA this summer, so that he can start doing some CNA work. It’s the dirty work of nursing. These days, a lot of the practical nursing care is done by CNAs, with an RN or BSN supervising several CNAs. If he absolutely despises CNA work, then maybe he should go an alternate route, like surgical tech, and do shift work while he goes to college for something else.
