Which certifications matter most for IT support roles

The certifications that matter most for IT support depend on whether you want to support end users, manage networks, or work with cloud infrastructure. CompTIA A+ is the foundation most employers expect for desktop and hardware support. CompTIA Network+ comes next if you want to move into network troubleshooting. Microsoft certifications (like Azure Fundamentals or Microsoft 365 Certified) matter if the job involves Windows environments or cloud services. Cisco CCNA is the standard for network-focused roles, but it's harder to get and takes longer than A+.

The path you choose depends on what kind of support work appeals to you. If you're starting from zero technical experience, A+ is the realistic first step — it covers hardware, operating systems, and basic networking in a way that prepares you for actual support tickets. If you already have some hands-on experience, you can sometimes skip A+ and go straight to vendor-specific certifications like Microsoft or AWS.

Key Takeaways

  • CompTIA A+ is the entry point most IT support jobs require or prefer, covering hardware, Windows, and basic troubleshooting.
  • CompTIA Network+ prepares you for roles that involve managing routers, switches, and network problems instead of just user devices.
  • Microsoft certifications (Azure Fundamentals, Microsoft 365 Certified) matter when the job involves cloud services or Office 365 environments.
  • Cisco CCNA is the gold standard for network engineering roles but requires more study time and hands-on lab work than CompTIA certifications.
  • Many employers care more about hands-on experience and the ability to troubleshoot than about which specific certification you hold.

CompTIA A+ for entry-level support roles

CompTIA A+ is the most common first certification for IT support because it covers the things you actually encounter in a support job: Windows and Mac operating systems, hardware troubleshooting, printers, networks, and security basics. The exam has two parts (Core 1 and Core 2), and most people study for 2 to 4 months before taking it. The cost is around $300 to $400 for both exams, plus study materials.

A+ doesn't require you to have worked in IT before, which is why it's the entry point. You can study from home using practice exams, video courses, or books. The exam tests both knowledge and hands-on scenarios — you need to know how to troubleshoot a computer that won't boot, replace a hard drive, set up a network connection, and handle basic security tasks. Most support jobs that don't require a degree will list A+ as preferred or required.

The certification is valid for three years. After that, you can renew it by passing a newer version of the exam or by earning a higher CompTIA certification (like Network+). Many people use A+ as a stepping stone to more specialized certifications rather than staying with it long-term.

CompTIA Network+ for network and infrastructure roles

CompTIA Network+ is the next step if you want to move beyond user support into network administration or infrastructure roles. It covers routers, switches, firewalls, VPNs, network security, and troubleshooting network problems across an organization. The exam is harder than A+ and assumes you already understand basic IT concepts, so most people take A+ first.

Network+ takes 3 to 6 months to study for, depending on your background. The exam costs around $300 to $400. Unlike A+, which is vendor-neutral, Network+ knowledge directly applies to Cisco equipment and other major network brands, so it's a natural bridge to Cisco certifications if you want to specialize further.

Network+ is less common as a strict requirement than A+, but many mid-level support roles and all network-focused positions prefer it. If you're working in a help desk and want to move into network operations or infrastructure, Network+ is the standard path.

Microsoft certifications for cloud and Windows environments

Microsoft certifications matter when the job involves Azure, Microsoft 365, Office 365, or Windows Server environments. Microsoft Azure Fundamentals (AZ-900) is the easiest entry point and takes 1 to 2 weeks to study for. Microsoft 365 Certified: Modern Desktop Administrator (MD-100 and MD-101) is more relevant if you're supporting users with Windows 10/11 and cloud-connected devices.

These certifications are cheaper than CompTIA ones — Azure Fundamentals costs around $100 to $165 for the exam. They're also faster to earn, which makes them useful if you already have some IT experience and want to specialize quickly. Many organizations use Microsoft products exclusively, so a Microsoft certification can be more valuable than a CompTIA one in those environments.

Microsoft certifications are vendor-specific, meaning they only apply to Microsoft products. If you work for a company that uses Microsoft infrastructure, they're worth pursuing. If you work in a mixed environment or want broad IT knowledge, CompTIA certifications are more portable.

Cisco CCNA for network engineering and advanced roles

Cisco CCNA (Certified Associate Network Engineer) is the industry standard for network professionals who want to design, build, and troubleshoot networks. It's significantly harder than CompTIA certifications and requires hands-on lab experience with actual Cisco equipment or simulators. Most people study for 4 to 6 months and spend $300 to $500 on exam fees and study materials.

CCNA is not an entry-level certification — employers expect you to have at least 1 to 2 years of networking experience before you take it. If you're starting from zero IT knowledge, you would take CompTIA A+ and Network+ first, then move to CCNA. The exam tests real-world scenarios like configuring routers, setting up VLANs, and troubleshooting network failures.

CCNA is worth the effort if you want to work as a network engineer, network administrator, or infrastructure specialist. It's less relevant for help desk or user support roles. The certification is valid for three years, and Cisco offers a clear path to higher certifications (CCNP, CCIE) if you want to specialize further.

How to choose between certifications

Start by looking at job postings for roles you want. If most of them list A+ or Network+, those are your targets. If they mention Microsoft Azure or Microsoft 365, add a Microsoft certification to your plan. If you're interested in network engineering specifically, plan for CCNA but start with CompTIA certifications first.

Your current experience matters too. If you've never worked in IT, A+ is the realistic starting point — it teaches you the fundamentals you need before moving to anything else. If you have 1 to 2 years of help desk experience, you can skip A+ and go straight to Network+ or a Microsoft certification. If you have 2+ years of networking experience, CCNA becomes a reasonable target.

Consider also whether you want to specialize or stay broad. CompTIA certifications are vendor-neutral and teach general IT knowledge that applies everywhere. Microsoft and Cisco certifications are more specialized but more valuable in environments that use those products heavily. Many IT professionals earn multiple certifications over their career — A+ first, then Network+, then a vendor-specific one based on where they work.

Study methods and realistic timelines

Most people study for certifications using a combination of video courses (like Professor Messer or Udemy), practice exams, and study guides. Video courses typically cost $10 to $50 and take 20 to 40 hours to complete. Practice exams cost $20 to $100 and are essential — you should score 80% or higher on practice exams before taking the real one.

The timeline depends on how much time you can dedicate per week. If you study 10 hours per week, A+ takes 2 to 3 months. If you study 5 hours per week, it takes 4 to 6 months. Network+ typically takes 50% longer than A+ because the material is harder. CCNA requires 100+ hours of study and hands-on lab work, so plan for 4 to 6 months minimum.

Many people study while working full-time, so realistic planning matters. Set a study schedule you can actually stick to rather than cramming. Most certification exams let you schedule them weeks in advance, so book your exam date before you start studying — it creates accountability and a real deadline.

Frequently Asked Questions

Do I need a certification to get an IT support job?

No, but most employers prefer it or list it as required. Many help desk jobs will hire someone with hands-on experience and no certification, especially if you can demonstrate troubleshooting skills. However, having A+ makes you more competitive and often leads to higher starting pay. Some larger companies and government contractors require certifications by policy.

Can I skip A+ and go straight to Network+ or Microsoft certifications?

If you already have IT experience or strong technical knowledge, yes. Some people with 1 to 2 years of help desk work skip A+ and go straight to Network+ or a Microsoft certification. However, if you're starting from zero, A+ teaches foundational knowledge you'll need for anything else. Skipping it usually means a longer, harder study process for the next certification.

How long are certifications valid?

CompTIA certifications (A+, Network+) are valid for three years. Microsoft certifications vary but are typically valid for one to two years. Cisco CCNA is valid for three years. After expiration, you can renew by passing an updated exam or by earning a higher certification in the same track. Many employers don't care if your certification has technically expired if you're actively working in the field.

Which certification pays the most?

Cisco CCNA typically leads to the highest salaries because it's the hardest to earn and most relevant for network engineering roles. Microsoft certifications pay well in organizations that use Microsoft infrastructure heavily. CompTIA certifications lead to entry-level and mid-level support roles, which pay less than specialized network or cloud roles. Your actual salary depends more on the job title and employer than on the certification itself.

Do I need to renew my certification?

Yes, but renewal is usually easier than the original exam. You can renew CompTIA certifications by passing a newer version of the same exam or by earning a higher certification. Some people renew by passing a related exam (like earning Network+ to renew A+). Check the specific certification's renewal policy before your expiration date.
