Go here and read this: https://grow.google/certificates/#?modal_active=none You don't have to send him there, but it will give you a better understanding of the various directions he could go. 

After that you need to spend time with him deciding what he's interested in, because if he's not interested he won't follow through. As you do that reference this list: https://www.roberthalf.com/blog/salaries...t-valuable to see what certs line up with his interests. The CompTIA certs are perfect for beginners, A+ and Network+ can get him started then move to company-driven programs like Microsoft, Cisco, Adobe and Oracle that all offer specific training that includes certification. 

My undergrad is Computer Science and I never worked a day in the field because I didn't enjoy the work, but I spent a lot of time on certificate programs in addition to my degree just to keep up on the trends. Then around 2008 I just dropped it entirely in favor of grad school to enhance my healthcare career where I ended up using almost all of the same skills I learned working in IT/IS. The skills are useful long term and transferrable even if he doesn't want to stay in technology for his entire career. College will certainly help if he decides to go into leadership, but the stuff here will lead to a solid career if he applies himself.
