It’s particularly valuable because it is regularly updated to reflect the latest IT trends and technologies. It covers foundational skills critical for various IT roles and is an essential stepping stone for anyone starting in IT.

This article will provide a comprehensive understanding of the intricacies of the CompTIA A+ test, the broad spectrum of topics included, and how you can equip yourself with the knowledge needed to pass the exam and thrive in the dynamic world of IT.

Understanding CompTIA A+ Certification

CompTIA A+ is an entry-level certification for those starting in the IT field. It covers fundamental computer and networking knowledge, focusing on the practical, hands-on skills required for IT operational roles and technical support. The certification recognizes the importance of not only understanding theoretical concepts but also being able to apply that knowledge in real-world scenarios.

The A+ certification was recently revised to focus primarily on the technologies and skills IT professionals need to sustain a hybrid workforce, including the ever-increasing reliance on SaaS applications and virtualization. As a result, the exams are designed to confirm that a candidate can troubleshoot and remotely diagnose and correct common software, hardware, or connectivity issues.

The Core 1 exam covers fundamental topics such as hardware, networking, mobile devices, and hardware troubleshooting. The Core 2 exam delves into operating systems, security, software troubleshooting, and operational procedures.

Exam Details

Those who wish to earn the A+ certification must complete two exams: Core 1 (220-1101) and Core 2 (220-1102). Both are computer-based tests with a combination of 90 multiple-choice, drag-and-drop, and performance-based questions. Test takers have a time limit of 90 minutes to complete each exam.

Preparing for the Exam

The most challenging aspect of passing these exams is the breadth of topics covered. It's not just about memorizing facts; it's about understanding a wide range of hardware, software, and troubleshooting concepts and applying them in practical scenarios. It varies per individual, but on average, it takes about 10-12 weeks of dedicated study. This can be longer for those new to IT or shorter for those with some experience or prior knowledge in the field.

Practical experience is not necessary before taking the exam, but it is highly beneficial as the exams include performance-based questions that test hands-on skills. Gaining some practical experience, even through labs or simulations, can be crucial for understanding the real-world application of the concepts.

Third-party materials can also be beneficial, but the focus should be on understanding core concepts and terms found on the exam. The best resources for exam preparation are the official CompTIA study guides and practice tests:

Guided Training Courses: Self-paced learning should always be part of your study plan, but training courses are the next best thing to real-world experience in IT. They provide a structured curriculum that aligns with the CompTIA A+ exam objectives. New Horizon’s CompTIA A+ course provides the background knowledge and skills you will require to be a successful A+ technician and will help you prepare to take the CompTIA A+ Core Series certification examinations (exam numbers 220-1101 and 220-1102).

Online Resources: Communities such as Reddit and the online CompTIA forums offer great and insightful discussions about IT concepts, professional experiences, and advice from others who plan to take or have already completed the CompTIA A+ exams.

Practice Tests: CompTIA offers official mock exams to help you familiarize yourself with the exam format and identify areas needing more attention. Completing practice tests reinforces the information you've studied, exposes you to different question formats, and can boost your confidence before completing the official exam.

The most important thing when preparing for these tests is to maintain consistency. Tailor your study plan to your learning preferences, establish a schedule, and assign regular study hours.

Registration and Taking the Exam

Each exam costs $246 and can be completed in person or online. Pearson OnVUE is a remote exam proctoring service that provides a secure and easy way to complete your CompTIA certification exam.

Certification candidates must agree with the CompTIA Candidate Agreement whether you take the exam online or in person. Beyond that, there are different requirements for online testing vs. in-person.


Online A+ Exam

There are online testing policies and procedures related to system requirements, your exam workspace, and testing for candidates under 17. You will have to run a system test on the same computer and network you will use to take your exam. You must also take photos of yourself and your exam workspace to confirm it meets CompTIA's requirements. That includes moving all books and writing objects out of arm's reach, unplugging additional monitors and computers, and clearing your walls of any writing.

CompTIA A+ Testing Center

On the day of your exam, you should arrive at least 15 minutes before your scheduled exam time. You will need to complete the sign-in procedures, which require you to present two forms of identification. Please note that you cannot bring personal items into the testing room, including bags, books, notes, computers, tablets, smartphones and smartwatches.

Make sure to get a good night's sleep before taking the exam. Start your day with a healthy breakfast, and arrive or log on early so you have time to check in and get settled before the test. Use your time wisely and do your best to answer every question.

After the Exam

Once you finish the A+ exam, you will be asked to complete an optional exit survey of about 12 multiple-choice questions. You will then receive your test scores: Candidates need at least 675 out of 900 to pass the 220-1101 exam. To pass the 220-1102 exam, test takers need a minimum passing score of 700 out of 900.

CompTIA does not offer free re-tests or discounts on exam retakes, and candidates must pay the exam price each time they attempt the exam. There is no waiting period between the first and second attempt to pass the exam; only before the third or any subsequent attempt is there a mandatory waiting period of at least 14 calendar days from the date of the last attempt.

Achieving the A+ certification will open new career paths and make you eligible for additional IT certifications. Many choose to pursue more advanced CompTIA certifications to specialize in specific IT areas, such as:

  • CompTIA Network+ for networking knowledge, such as network infrastructure and protocols.
