Frequently Asked Questions

What is the CompTIA A+ certification?

CompTIA A+ is an entry-level IT certification that validates foundational skills in hardware, software, networking, and troubleshooting. It's widely considered the starting point for a career in IT support and help desk roles. The certification is vendor-neutral, meaning it covers concepts across different operating systems and device manufacturers rather than focusing on a single brand.

How many parts does the CompTIA A+ have?

The CompTIA A+ requires you to pass two separate assessments - Core 1 (220-1101) and Core 2 (220-1102). Core 1 focuses on mobile devices, networking, hardware, and cloud computing. Core 2 covers operating systems, security, software troubleshooting, and operational procedures. You have to pass both to earn the full A+ certification.

What scores do I need to pass the CompTIA A+?

Core 1 (220-1101) requires a passing score of 675 on a 100-900 scale, and Core 2 (220-1102) requires 700 on the same scale. CompTIA uses scaled scoring, so it's not a simple percentage calculation. The different passing thresholds reflect the varying difficulty levels between the two parts.

How much does the CompTIA A+ cost in total?

Each CompTIA A+ voucher costs $358 USD, and since you need to pass two separate assessments, the total registration cost is $716. That doesn't include study materials or training courses. It's worth looking into CompTIA's bundled pricing or checking if your employer offers certification reimbursement - many companies in IT will cover the cost for you.

How long should I study for the CompTIA A+?

For someone with little or no IT experience, plan on about 2-4 months of consistent studying, spending around 1-2 hours per day. If you've already been working in an IT support role, you might be ready in 4-6 weeks. A lot of people tackle Core 1 first, take it, and then shift their study focus to Core 2. Hands-on practice with actual hardware and virtual machines is just as important as reading the textbook material.

What topics does the CompTIA A+ 220-1101 (Core 1) cover?

Core 1 covers five main domains: Mobile Devices (15%), Networking (20%), Hardware (25%), Virtualization and Cloud Computing (11%), and Hardware and Network Troubleshooting (29%). The troubleshooting domain carries the most weight, so you'll want to make sure you're comfortable diagnosing common hardware and connectivity issues. Expect questions on ports, cables, RAM types, motherboard components, and wireless networking standards.

What topics does the CompTIA A+ 220-1102 (Core 2) cover?

Core 2 focuses on four domains: Operating Systems (31%), Security (25%), Software Troubleshooting (22%), and Operational Procedures (22%). Operating systems make up the biggest chunk - you'll need to know Windows, macOS, Linux, and mobile OS concepts. The security section covers malware removal, physical security, and best practices. Don't overlook operational procedures, which covers documentation, change management, and disaster recovery basics.

Does the CompTIA A+ certification expire?

Yes, the CompTIA A+ is valid for three years from the date you pass. To renew it, you need to earn 20 Continuing Education Units (CEUs) within that period or pass the current version of the certification again. You can earn CEUs through training courses, webinars, higher-level certifications, and other approved activities. Earning a higher CompTIA cert like Network+ or Security+ also automatically renews your A+.
