Complete Overview
CompTIA A+ is the industry-recognized credential for launching a career in IT. This certification validates foundational IT skills across multiple technologies and operating systems, proving you have the skills to perform critical IT support tasks. A+ is the starting point for millions of IT professionals worldwide and remains the most sought-after entry-level IT certification.
CompTIA A+ certification requires passing two exams: Core 1 (220-1101) and Core 2 (220-1102). Core 1 covers mobile devices, networking, hardware, virtualization, and cloud computing. Core 2 focuses on operating systems, security, software troubleshooting, and operational procedures. Together, these exams validate that you possess the essential skills for entry-level IT support roles.
The A+ certification is unique because it's vendor-neutral, meaning the skills you learn apply across all manufacturers and platforms. Whether you're supporting Windows, macOS, Linux, iOS, or Android devices, A+ provides the foundational knowledge you need. This vendor-neutral approach makes A+ holders valuable in any IT environment, from small businesses to Fortune 500 enterprises.
A+ has been around since 1993 and has certified over 1.3 million IT professionals worldwide. The certification is regularly updated to reflect current technology, with the most recent update in 2022 introducing expanded coverage of remote work support, automation, and cloud technologies. Major employers like Dell, HP, Intel, Apple, and the U.S. Department of Defense recognize A+ as proof of technical competency.
For those just starting in IT, A+ provides structured learning and validates your skills to employers. For career changers from other fields, A+ offers a clear path into the technology industry. The certification is also approved by the U.S. Department of Defense, making it valuable for government and contractor positions.

Common Mistakes to Avoid
Studying outdated material
Always use current exam objectives (220-1101/1102). The exam updates regularly with new technologies.
Ignoring performance-based questions (PBQs)
PBQs require hands-on skills. Practice in virtual labs or build a home lab to prepare for simulations.
Memorizing without understanding
Focus on understanding concepts. The exam tests application of knowledge, not memorization.
Underestimating Core 2
Core 2 has a higher passing score (700 vs 675) and covers more abstract concepts. Don't assume it's easier.
Not getting hands-on experience
Build a home lab, volunteer for IT tasks, or use virtual labs. Practical experience is essential.
Skipping the troubleshooting methodology
CompTIA's troubleshooting methodology appears throughout both exams. Know the steps cold.
Exam Day Tips
- 1
Tackle performance-based questions (PBQs) last if you're unsure - flag them and return
- 2
Read every word in the question - CompTIA is known for tricky wording
- 3
For multiple-answer questions, note how many answers are required
- 4
Use process of elimination for difficult questions
- 5
Manage time carefully - 90 minutes for 90 questions means 1 minute per question
- 6
Don't leave any questions blank - there's no penalty for guessing
- 7
Review flagged questions if time permits
- 8
Stay calm with simulations - they test the same concepts as multiple choice

Frequently Asked Questions
Do I need to pass both exams?
Yes, A+ requires passing both Core 1 (220-1101) and Core 2 (220-1102). You can take them in either order and have three years to complete both.
Which exam should I take first?
Most people take Core 1 first as it covers more tangible hardware topics. Core 2 is more abstract with OS and security concepts.
How long should I study?
With no IT experience: 3-4 months. With some experience: 6-10 weeks. Plan for about 100-150 hours total study time.
Is A+ worth it for career changers?
Absolutely. A+ is the fastest path into IT for career changers. It proves foundational knowledge to employers who might otherwise require experience.
Does A+ expire?
Yes, A+ is valid for three years. You can renew through continuing education (CEUs) or by taking a higher-level certification.
A+ or Network+ first?
A+ should come first. It covers foundational concepts that Network+ assumes you already know. The CompTIA pathway starts with A+.
