If you are new to IT and want broad preparation for entry-level support work, start with CompTIA A+. Choose Network+ first if you already have equivalent IT fundamentals and want to focus on networking; choose Security+ first if you know IT and networking basics and are aiming for a cybersecurity foundation. These are practical learning recommendations, not exam prerequisites: CompTIA’s certification guide lists no formal prerequisites for any of the three.
How to choose your first certification
Choose based on what you already know and the work you want to prepare for. A+ covers a broad set of support-oriented skills; Network+ concentrates on networking; Security+ introduces foundational cybersecurity concepts. A certification can guide your learning, but the material reviewed does not establish that any one of these guarantees a job, a particular salary, or a hiring advantage.

You are starting from the basics
A+ is the clearest starting point if you need to build a foundation across devices, operating systems, troubleshooting, networking, security, and support procedures. Its breadth gives a beginner a way to study the kinds of concepts that connect everyday technical support tasks, rather than beginning with only one specialist area.
#1 Best Overall
You are still deciding on a direction
If you have not settled on networking or cybersecurity, A+ offers a broader introduction to IT support and operations. The CompTIA guide recommends 9–12 months of hands-on lab or field experience involving mobile, desktop, and networking tasks as background for A+. That is recommended experience, not an entry requirement.
When to start with Network+
Consider Network+ first if you already understand the relevant IT fundamentals and your goal is specifically networking or network administration. CompTIA’s guide recommends A+ knowledge plus at least 9–12 months of hands-on entry-level or junior networking experience. It does not make passing A+ a formal condition for taking Network+.
For the N10-009 version described in CompTIA’s Network+ exam objectives, the exam has a maximum of 90 questions, includes multiple-choice and performance-based question types, and lasts 90 minutes. The objectives assign these domain weights:

Those percentages describe the N10-009 exam objectives; they are not measures of a topic’s importance on the job or of exam difficulty. The objectives document displays a 2023 copyright, and its exact release date was not established.
When to start with Security+
Security+ is a reasonable first certification when you already understand IT and networking fundamentals and specifically want a cybersecurity foundation. It covers security concepts, threats and mitigations, architecture, security operations, and program oversight—not just isolated security terminology.
CompTIA’s guide recommends Network+ knowledge plus two years of IT administration experience with a security focus. This is recommended background, not a formal eligibility rule. If those foundations are new to you, studying A+ and networking fundamentals first can make Security+ concepts easier to place in context.
Rank #4
Is there a required order?
No formal prerequisite between these certifications is listed in CompTIA’s guide: you do not have to pass A+ before sitting Network+, or pass Network+ before sitting Security+. The suggested sequence—A+, then Network+, then Security+—is a progression of knowledge and experience, not a compulsory exam ladder. If you can demonstrate equivalent fundamentals and have a clear networking or security goal, you can choose that path directly.
CompTIA’s guide recommends 9–12 months of hands-on experience for A+, A+ knowledge plus 9–12 months of networking experience for Network+, and Network+ knowledge plus two years of security-focused IT administration for Security+. Treat these as experience recommendations, not minimum eligibility periods.

A practical decision checklist
- Choose A+: You are new to IT, want broad support-oriented preparation, or have not chosen a specialty.
- Choose Network+: You already have the fundamentals and want to concentrate on networking or network administration.
- Choose Security+: You understand IT and networking basics and want an introductory cybersecurity credential.
- Check the current exam code first: Exam versions and study materials can change. Confirm the live code and availability with CompTIA before buying a book or scheduling an exam.
How to choose study materials
Once you have selected a certification, match any study guide or exam-prep material to the current exam code—for example, the N10-009 objectives discussed above or the SY0-701 code named in CompTIA’s guide. A book is optional, not a stated requirement or a guarantee of passing. Verify the code and regional availability on CompTIA’s official pages before purchasing or booking; current prices and retirement dates for every version are not established here.
