How Important Are Math, a CS Degree, and Certifications for SysAdmin or Networking Careers?
Asked by

I'm a high school student interested in becoming a systems administrator or network engineer. My parents believe I need advanced theoretical math and a five-year computer science degree to succeed, and they think attending a technical institute while earning Linux or Cisco certifications would be a waste of time. For people working in IT operations, how much advanced math do you actually use day to day? How are certifications, hands-on experience, and practical skills valued compared with a traditional four-year degree?
Answers
You generally won’t use much advanced math in systems or network administration. Day-to-day work is more about troubleshooting, logical reasoning, learning unfamiliar technology, and communicating with users and project teams. Subnetting and basic budgeting are about as mathematical as most roles get, and tools can handle the calculations.

A technical program plus practical experience and respected certifications can absolutely get you started. Linux and Cisco credentials are useful when paired with labs, home projects, and real troubleshooting experience. This route may get you into the workforce faster and at lower cost, although you may need additional education or experience later to move into certain roles.

A bachelor’s degree is not strictly required to become a sysadmin or network administrator, but it can make getting past hiring filters much easier. Some employers require a four-year degree even when the actual work does not involve advanced theory. A degree also gives you broader options if you later move toward engineering, software, security, or management.

Neither path is automatically a waste. A university degree usually offers broader foundations and a higher career ceiling, while a technical institute and certifications provide a quicker, more focused entry into IT. If university is affordable and you are unsure what area of technology you want long term, the degree gives you more flexibility. If you already know you want infrastructure work, a technical program with certifications, labs, and entry-level experience is a valid route.

A computer science degree is especially valuable if you want programming, systems development, research, or a deep understanding of how computing works internally. For hands-on IT operations, the most important abilities are diagnosing problems, automating repetitive tasks, understanding operating systems and networks, and continuing to learn as technology changes. Choose based on the kind of work you want rather than assuming one credential is required for every technology career.

AmberLynx54: That degree requirement can still matter years later. People with plenty of practical experience sometimes get screened out automatically when a job lists a bachelor’s degree as a requirement.
