How certain is he that he wants to be a nurse?
It sounds like your son is still in high school and has the opportunity to complete an AS early, so I don’t see the rush. He’ll still spend the same amount of time in school as if he majored in someone else, and getting a transfer degree keeps his options open. If he’s just now starting, I’m guessing he’s between 15 and 17 - that’s pretty early in life to lock yourself into a specific career path. I think there’s also major value in the developmental phase of college outside of just vocational training - especially for a nurse, who may be dealing with people who are having some of the worst experiences of their lives. Some life experience and perspective can only be helpful.
That said, nursing is a thriving career that will always be needed and a great base for a variety of other careers (I know at least two former nurses who work at my tech company, in two different roles, neither related to healthcare tech). And I’d understand if money was a concern. (However…I would like to emphasize that with this route, assuming he’s 16 now, we’d be talking about a practicing nurse at between 18 and 20 years old, and he may have a hard time finding a job that young…)
Either way, I have a lot of family in nursing (including my mother and several close cousins), and I’d strongly recommend that he works a few years after getting his BSN. It’s a practical degree, and it’s meant to be built on top of a foundation of experience in nursing. I think many hospitals would be wary to hire a DNP without any actual nursing experience - you can’t go into the nurse leadership roles that DNPs usually inhabit, as none of the other nurses would ever listen to you (nor could you manage them), but you’d be too expensive to employ in a regular nursing role that they could just hire a BSN for.
Also - he has to think about his future career in nursing, not just the situation right now. While ADN/RNs may be getting hired right now, especially because of the pandemic, the field is moving towards a BSN being the base for the nursing career. It carries many benefits for patient care.
My mom made this mistake in an earlier era - she went to a diploma program to get her LPN at a time when LPNs were still getting hired but many facilities were moving towards hiring only RNs. While she did get hired, she found that she got the worst shifts, low-level tasks, and she couldn’t advance in her career there - her lack of an RN was holding her back. She also got paid a lot less than the RNs (and a LOT less than the BSNs). She can’t work anymore, but if she could, I think she’d have a hard time getting hired in a hospital - and she’s said as much herself. (She worked as a school nurse before she became disabled.)
