  • the finance industry
  • manufacturers

Qualifications and training required

There are routes into this career for both graduates and school leavers.

It's occasionally possible to enter this profession with a degree in any subject. However, many employers favour relevant subjects such as computer science, software engineering and electronic engineering. Once in employment, candidates are often expected to study for further professional qualifications.

Network administrators need to understand how to connect devices to form a fast and efficient network. Therefore it helps if graduates have experience of running networks on specific network operating systems, perhaps in a school, a university or in a company's IT department. You can also apply for industrial placements and summer internships.

For school leavers, taking a short course in networking or network design (such as those run by Cisco) can be helpful but may not be a requirement of all school leaver employers.
