What Is the CompTIA A+ Certification? A Certification to Start Your IT Career

The CompTIA A+ certification is an entry-level qualification in the information technology (IT) industry. Issued by the IT association CompTIA, the A+ certification is widely accepted as an industry standard certification often used to kickstart a career in IT.

Here's a quick look at the basics:

• The CompTIA A+ is composed of two exams in the Core Series—220-1201 and 220-1202.

• Each exam costs £133 in the UK as of August 2025, totaling £266 [1].

• The exams will test your knowledge of operating systems, data, security, networking, hardware, and help desk services.

• There are several training programmes that will prepare you for the CompTIA A+ exams, including the Google IT Support Professional Certificate, and the CompTIA CertMaster Learn for A+ Core 1.

What jobs can I get with the CompTIA A+ certification?

The CompTIA A+ certification is widely recognised as the go-to certification for an entry-level position in IT. Here are a few entry-level jobs that often call for the CompTIA A+ certification and their average UK salaries, according to August 2025 data from Indeed:

• Help desk analyst: £25,779 [2]

• IT technician: £28,088 [3]

• Help desk specialist: £28,109 [4] 

• Technical support specialist: £28,531 [5]

• Desktop support analyst: £32,630 [6]

Keep in mind that this number might change depending on where you’re located—IT jobs in large cities, such as London, might pay more than those in smaller towns to adjust for the cost of living, for example. Other factors, like your education level and previous experience, can also influence your salary.

What’s on the CompTIA A+ exam?

The exam for the certification combines multiple-choice questions and performance-based questions. The exam broadly tests your knowledge of various IT basics, including hardware, software, networking, operating systems, and security. Expect questions to cover the following domains:

How to get a CompTIA A+ certification

There are several ways you can prepare for the CompTIA A+ exam: 

• Online, instructor led-courses can prepare you for the exam. 

• Classroom training through a CompTIA Authorised Partner.

• Self-study—learning through online videos or books without an instructor—can also work. 

Whatever method you choose, CompTIA recommends dedicating 120 hours to prepare for the test and 12 months of hands-on experience

CompTIA A+ training courses

CompTIA offers several resources, including books, instructor-led online courses, and training programmes that allow you to progress at your own pace. For example, the CertMaster Learn + Labs for A+ is an online course that includes lessons, practice questions, and a practice exam. 

The Google IT Support Professional Certificate programme has five courses that cover the entry-level fields of IT, incorporates hands-on projects that simulate real-world scenarios.

Here’s a quick breakdown of the two.

• Price: $59 (approx £44 as of August 2025) a month subscription, with a free trial week (subject to change).

CompTIA A+ vs. CompTIA IT Fundamentals (ITF+)

CompTIA offers several separate entry-level certifications, including the CompTIA A+ and the CompTIA IT Fundamentals, or ITF+. They’re each slightly different. The CompTIA A+ is billed as a certification that will test you on the knowledge needed to land an entry-level IT job. The ITF+, on the other hand, is designed for students and professionals who want to see if IT is the right career fit for them. The ITF+ exam is also used by non-IT professionals who want a broad introduction to the field.

Which should you choose?

If you’re still on the fence about whether you’d like a job in IT, getting the ITF+ can be a good way to test the waters. If you know you want to commit to IT work and are ready to gain job-ready skills, the A+ certification is probably a better path.

Leveraging your certification

If you’ve passed the exam, take some steps to ensure the certification is visible to key players. Add it to your CV and LinkedIn, and if you’re already in a related career, inform your employer. It may also be worth looking at other entry-level IT certifications—keeping an eye on other certifications may help you make decisions on what you’d like your future career to look like.

What's next after the CompTIA A+?

For many IT professionals, the CompTIA A+ is the first of many certifications earned over the course of their careers. Since the A+ certification is fairly general, you may choose to move into an IT specialisation, like networking, cybersecurity, or cloud computing. CompTIA offers more advanced certifications in these fields, as do many other reputable organisations.
