I used to teach software development at a part-time bootcamp. The part-time program was especially interesting because it tended to attract an older crowd, people with families and full-time jobs.

I don't know if I ever had students in their 60s, but I'm pretty sure I had students in their 50s (I don't know their birthdates so I'm really just guessing when it comes to age).

On average, it was definitely harder for the older students to find work, but it's absolutely possible. Some companies will really appreciate having people with more life experience, more maturity.

I think the first step would be to see if your dad actually enjoys doing software development. Lots of people just hate it. Doing some beginner JavaScript or Python tutorials could be a good place to start. If it sparks excitement, I think he should absolutely consider doing a bootcamp or similar program.

I think it's an uphill climb, but if he enjoys doing it and he doesn't give up easily, I'm confident it could be a viable path for him.
