The Best Certifications to Land an IT Support Interview
What hiring managers actually look for on an IT support resume
Most people asking "How do I pass the screening for a helpdesk job?" have already noticed the pattern. Job posts list three or four certifications, recruiters ping the ones that match keywords, and everyone else waits. If you are trying to break into IT support, the certification you pick first shapes the next twelve months of your career. Pick well and you interview within weeks. Pick poorly and you spend a semester studying for something no one asks about at the entry level.
This is an opinionated ranking of the IT support certifications that consistently move resumes to the interview pile, and the order I think you should attempt them. For a deeper dive, check out Are IT Certifications Still Worth It in 2026?.
Tier one: CompTIA A+
A+ is the closest thing IT support has to a default credential. It is vendor neutral, it covers the hardware, operating systems, mobile devices, networking basics, and troubleshooting method that a level-one technician actually uses, and hiring managers recognise it without needing to Google it. When recruiters filter for CompTIA A+ jobs, this is the exact string they type.
The exam is split into two parts, Core 1 and Core 2, and you need both to be certified. Core 1 is the hardware and networking half, and it is where most candidates underestimate the breadth of the objectives. Do not walk in without a full-length rehearsal. A timed practice exam for CompTIA A+ Core 1 tells you within ninety minutes whether your weak spot is printers, cloud concepts, or subnetting, and it is far cheaper to find out on a mock than at a Pearson VUE seat.
Before you sit the official exam, a free CompTIA A+ Core 1 readiness check can tell you whether your review time is pointed at the right section.
If you buy one thing before your booking, buy the A+ Core 1 mock test pack and work through it twice. Looking for more detail? See The Highest-Value IT Certifications to Target This Year.
Tier two: the vendor entry certifications
Once A+ is on your resume, the follow-on choice depends on where you want to work.
- Microsoft 365 Fundamentals (MS-900) or Azure Fundamentals (AZ-900) — almost every organisation runs on Microsoft 365, and a fundamentals badge signals that you can talk to end users about licensing, Teams, SharePoint, and identity without freezing.
- Google IT Support Certificate — not a formal certification in the same sense, but it is well recognised for career changers and pairs naturally with A+.
- ITIL 4 Foundation — cheap, quick, and it teaches you the language of tickets, incidents, and change control that every service desk uses. Managers notice it.
None of these replace A+ at the entry level. They stack on top of it.
Tier three: Network+ and Security+
These are where the "IT support to sysadmin" path really begins. Network+ deepens the networking coverage A+ only skims, and Security+ opens the door to any role that touches compliance, which today is most of them. I would not attempt either before A+ unless you already work in the field, because the assumed baseline is exactly the material A+ covers.
If your goal is to be a network technician or a junior security analyst within two years, plan the sequence now: A+ this quarter, Network+ next, Security+ after that.

Certifications that are overrated for entry-level support
A few credentials get recommended in forums that I think are traps for someone still trying to land a first interview.
- CCNA is a serious networking certification and worth pursuing later, but studying for it before you have a job wastes months. It does not qualify you for helpdesk roles that A+ would have unlocked in a fifth of the time.
- Cloud architect certifications at the associate or professional level. Employers hiring for support do not expect them, and studying for them without production access is painful.
- Any cybersecurity certification above Security+ as a first credential. CISSP explicitly requires five years of experience. Do not try to skip the ladder.
A realistic six-month plan
Month one and two: study A+ Core 1, using the exam objectives as your table of contents. Month three: sit Core 1. Take a full-length mock test the week before, and again two days before, to calibrate pace. Month four and five: Core 2. Month six: pick MS-900 or ITIL 4 Foundation based on the job posts in your city.
If that outline feels too rigid for your schedule, the free CompTIA A+ Core 1 study plan can stretch or compress it around the hours you have.
Every stage above is easier when you rehearse in the format the awarding body uses. A properly timed practise exam trains the pacing muscle that content review alone never touches. Grab the Core 1 practice pack when you start month two, run it under exam conditions, and treat every miss as a study prompt for the following week. That is the shortest honest route from zero credentials to an interview invitation.
