The CompTIA A+ certification is the industry standard for establishing a career in IT. This performance-based certification validates foundational skills across a variety of devices and operating systems, making it the go-to credential for technical support and IT operational roles. The CompTIA A+ core series requires passing two exams: Core 1 (220-1101) and Core 2 (220-1102).
It is designed for individuals looking to enter the IT workforce, including high school or college students, career changers, or entry-level technicians who want to validate their skills and enhance their employability.
This certification covers the essential knowledge needed for entry-level IT roles. The curriculum is split across two domains, corresponding to the two required exams:
CompTIA A+ Core 1 (220-1101) focuses on mobile devices, networking technology, hardware, virtualization, and cloud computing.
Mobile Devices: Installing and configuring laptops and other mobile devices.
Networking: Explaining types of networks and connections (TCP/IP, WIFI, SOHO).
Hardware: Identifying, using, and connecting hardware components and devices, including printing.
Virtualization & Cloud Computing: Comparing and contrasting cloud computing concepts and setting up client-side virtualization.
Hardware & Network Troubleshooting: Troubleshooting device and network issues.
CompTIA A+ Core 2 (220-1102) focuses on operating systems, security, software troubleshooting, and operational procedures.
Operating Systems: Installing and configuring Windows, Mac, Linux, and mobile OS.
Security: Identifying and protecting against security vulnerabilities for devices and their network connections.
Software Troubleshooting: Troubleshooting PC and mobile device issues, including application security support.
Operational Procedures: Following best practices for safety, environmental impacts, communication, and professionalism.
The CompTIA A+ certification consists of two separate exams (220-1101 and 220-1102). You must pass both to earn the certification.
Exam Format: Each exam features a maximum of 90 questions. The questions are a combination of multiple-choice (single and multiple response), drag-and-drop, and performance-based questions (PBQs). PBQs test your ability to solve problems in a simulated environment.
Time Limit: You have 90 minutes to complete each exam.
Passing Score: The passing scores are different for each exam:
CompTIA A+ 220-1101 (Core 1): 675 (on a scale of 100-900)
CompTIA A+ 220-1102 (Core 2): 700 (on a scale of 100-900)
Successfully passing the CompTIA A+ exams requires a combination of conceptual knowledge and hands-on experience.
Study Strategies:
Official Study Guides: Start with official CompTIA CertMaster Learn materials or reputable third-party study guides (like those by Mike Meyers or Professor Messer).
Practice Tests: Taking practice exams is crucial. They help you get used to the question format, manage your time, and identify areas where you need more review.
Hands-on Labs: Use virtual lab environments or set up your own practice lab with old computers to gain practical experience with hardware and software configuration.
Exam Centers: CompTIA exams are administered by Pearson VUE. You can take the exams in two ways:
In-Person Testing: You can schedule your exam at one of the thousands of Pearson VUE authorized testing centers worldwide. This offers a traditional, proctored environment.
Online Testing (OnVUE): You can take the exam from the comfort of your home or office. This option requires a reliable internet connection, a webcam, and a private space, and it is proctored remotely.
Earning your CompTIA A+ certification significantly boosts your resume for entry-level IT positions. The certification is highly recognized by employers and unlocks several career paths, including:
Help Desk Technician
