What Beginners Get Wrong About IT Certifications

Certifications help when they match a role and are backed by proof — not as a scoreboard. The problem Beginners are told certifications are the key to IT, so they buy the most popular one, pass it, and are surprised when interviews still go badly. A certificate proves you can pass an exam; it does not, on its own, prove you can do the job. Why this matters now Certifications remain useful signals, and official providers like CompTIA, Microsoft, AWS, Cisco and Google keep their exam objectives public and current. But as AI makes it easier to grind practice questions, employers lean harder on whether you can actually apply the knowledge. The value of a certificate is increasingly in what you can demonstrate alongside it. There is also a cost reality. Exams, courses and retakes add up in money and time, and career changers usually have limited amounts of both. Spending three months and a chunk of savings on a certificate that no target role actually asks for is one of the most common and most avoidable mistakes in an IT transition — which is exactly why the order you choose them in matters. The practical framework Use certifications as targeted evidence, not as a scoreboard. Three rules: Match objectives to a job. Open the certification's published objectives next to a real job description. Overlap means it is relevant; no overlap means it is a hobby. Prove the same skills in practice. For each major objective, build one small artefact that shows you can do it, not just recall it. Stop at enough. One well-chosen, well-demonstrated certification beats three unrelated ones. Sequence them to roles, not to availability. Which one first? Let the target role decide, not the brand with the loudest marketing. As a rough guide: a vendor-neutral foundation (such as CompTIA A+ for general IT support, or Network+/Security+ as you specialise) suits broad support roles; a cloud-fundamentals exam (Microsoft Azure or AWS) suits cloud-leaning roles; Cisco-flavoured paths suit networkin
