Network and Systems Administrator

One ladder, four rungs, and only the top two are growing

This page covers a family, because in Florida they are taught together and people move up through them. The honest picture is a shrinking bottom and a growing top.

⚠⚠⚠ This is the only path on this site whose anchor occupation is projected to shrink — 323,600 jobs falling by 13,200 over the decade. That is not a reason to avoid it. It is a reason to enter it with a plan to move.

⚠ O*NET and the BLS agree on direction and differ on size: O*NET puts administrators at a decline of 1% or lower on the 2024–34 projections; the BLS puts it at −4% on 2025–35. Both say down. There are still 14,300 openings a year, because replacement demand does not stop when growth does — so the jobs exist; the number of them is not increasing.

What the work actually is

O*NET, on network and computer systems administrators: installing, configuring and maintaining an organisation's networks and servers; planning and implementing network security measures; performing data backups and disaster recovery; diagnosing and resolving hardware and software problems; monitoring network performance and user access.

⚠ It is the most hands-on computing job on this site, and the one where a home lab teaches you most of what the course does. It is also the one most exposed to being on call: when the network is down, nobody else can work.

⚠⚠ Why the middle is shrinking, and what to do about it

The BLS names the two advancement routes explicitly: administrators “may advance to become computer network architects” and “also may advance to managerial jobs in IT departments, such as computer and information systems managers”. Separately, the support-specialist handbook says support staff “advance to other information technology positions, such as information security analysts, network and computer systems administrators and software developers”.

⚠⚠⚠ Read those two statements together and the strategy writes itself. The federal projections show the routine administration and support work contracting while design (architect, +7%) and defence (security, +21%) expand. The rung is a good place to stand and a poor place to stay.

• Aim at architect if the infrastructure itself is what interests you: $134,050, growing, and the natural promotion from this job.
• Aim at security if incidents and defence interest you: $129,180, growing fastest of any computing path here, and the federal handbook says this administration job is the usual place analysts come from.
• Aim at IT management if the organisational side appeals — the other route the handbook names.
• ⚠ Learn cloud deliberately, whatever your programme teaches. The shrinkage is in on-premises administration; the same skills applied to cloud platforms are not shrinking.

⚠⚠ Florida teaches this more widely than any other computing subject — mostly in clock hours

56 Florida public institutions award in this family, producing 1,733 credentials in the 2023 award year. It is where the technical colleges dominate: on the networking code, Sheridan 59, FSCJ 38, Atlantic Technical 23, Immokalee Technical 22, Tom P. Haney 21, Traviss 19, Emerald Coast 19, Radford Locklin 18. On the systems-administration code the balance flips to the state colleges: Valencia 414, Miami Dade 205, Broward 106.

⚠⚠⚠ The clock-hour courses reach four times as many institutions as the credit-bearing ones. The PSAV stack is genuinely well designed — CTS 0022 help-desk assistant, CTS 0023 network support administrator, CTS 0024 senior network administrator, each 150 hours, each an exit point you can work from. It is a real and sensible route into the work.

⚠⚠ But look again at the ladder table at the top of this page. The rungs those certificates reach are the ones projected to decline; the rungs that are growing — architect, security, management — expect a degree. So the clock-hour route gets you working fastest and positions you worst for the direction this field is moving. If you take it, take it knowingly, and plan how you will add the credit later.

Necessary skills

• TCP/IP and routing, properly. Not memorised for an examination — understood well enough to diagnose from a packet capture.
• Linux and Windows server administration. Both. Programmes that teach only one leave a gap employers notice.
• Scripting and automation. PowerShell, Bash, Python. This is the difference between an administrator who scales and one who is replaced by the automation.
• Cloud platforms. The part of this job that is growing, and the part many Florida programmes still treat as an elective.
• Methodical troubleshooting under pressure, with people waiting and a manager asking for an estimate.
• Documentation. The network you cannot hand over is the network you can never leave.

Advice

⚠⚠ Enter here, but do not plan to retire here. The jobs are real and there are 14,300 openings a year, but the occupation is contracting. Pick your next rung — architect, security or management — in your first year, not your fifth, because it determines whether you need the degree.

⚠ Get certified, and get certified early. Employers in this field screen on vendor certifications more than on the degree. Ask a programme which examinations it prepares you for, whether the fee is included, and what its pass rate is.

⚠ Decide the credit question with the ladder in front of you. The clock-hour route is faster to a first job and does not transfer. If architect or security is the destination, the credit route is worth the extra time.

And build a home lab. Second-hand switches, a virtualisation host, a few virtual machines. Nothing else in computing rewards it as directly: this is a field where employers will happily hire someone who can clearly demonstrate that they have broken and fixed the thing already.
