CompTIA A+ Certification and Why You Need It

The benefit of the CompTIA A+ Certification is that it is proof that you know and have validated the hardware and software knowledge necessary to troubleshoot and repair computers. The CompTIA A+ Certification can be presented to employers and clients alike as proof of your competency and skill in this area. This certification is valid for three years from the day that you attain the certification, after which time you must renew by taking the newest version of the exam, or by taking a higher level certification exam. You can find out more on the subject at https://certification.comptia.org/continuing-education.

Formed in 1982, CompTIA was originally named the Association of Better Computer Dealers. It is a company focused on providing research, networking, and partnering opportunities to its 19,000 members in 100 countries. In 1993, in response to the need for vendor-neutral, entry-level PC certification, the company created the A+ Certification.

Prior to CompTIA creating the A+ Certification, there were many places where a person could get hardware and software certifications. However, such training was often very expensive, difficult to get, and not designed for accessibility for most people. Microsoft, Novell, IBM, and other software companies offered software certifications, but these were specifically focused on teaching high-level support skills for these products, were difficult for average users or support people to attain, and lacked relevance for most day-to-day work.

IBM, HP, Compaq, Sun, and other hardware companies offered hardware repair and maintenance certifications, but again, these were specifically focused on their hardware — and more on the peculiarities of their own platforms, and not always covering the basics of configuration and maintenance. CompTIA stepped in to fill the gap that a majority of users fell into, which is a hardware and software neutral certification that covered all the basics required by a support person. This certification can then be followed by vendor-based certifications, if desired, but the A+ Certification by itself proves a firm grasp of the basics.

An A+ Certification gives employers confidence that existing employees or new recruits have a level of knowledge with which they can do their jobs efficiently. It also gives employers a yardstick against which recruits and employees can be measured. And an A+ Certification also allows clients to rest assured that the person they hire to fix their computers has the knowledge to do so without blowing up equipment or deleting valuable data. This provides clients with peace of mind and increases repeat business. In the end, with the CompTIA A+ Certification on your side, you have more opportunities open to you in your career path.

Checking Out the Exams and Their Objectives

You have to take two exams to get your CompTIA A+ Certification. Both exams are required. The first required exam is the CompTIA A+ Exam 220-1001, which focuses on the hardware aspects of computer repair. The second required exam is the CompTIA A+ Exam 220-1002, which focuses on configuring and troubleshooting the software aspects of a system in a corporate network environment.

Revised exams for CompTIA A+ were released in 2019. In addition to traditional multiple-choice questions, the CompTIA A+ exams include an unspecified number of performance-based questions (PBQs); these are short exercises that test your ability to solve problems in a simulated environment. The CompTIA website has a sample performance-based question that can be viewed at http://certification.comptia.org/testing/about-testing/performance-based-questions-explained.

You have 90 minutes to complete each exam; Table 1-1 contains the number of questions and passing score for each exam. CompTIA is releasing the exams as linear format exams — standard timed exams — taken on a computer. After CompTIA gathers grading statistics, it might re-release the exams as adaptive exams (what CompTIA has done in the past), but there is no current announcement that this is planned. In this adaptive exam, you will be asked a minimal number of questions (usually about 15), and then asked additional questions based on any incorrect answers. The exam adapts to your wrong answers by choosing additional questions for you from the area where you are weaker.
