New CompTIA A+ Exam Requirements

CompTIA A+ Exam Requirements

The A+ exam was just updated to the 220 1001/1002.  Below is what to expect.

Price

pepi-stojanovski-509192-unsplash

The  CompTIA A+ Exam A+ exam is broken down into two exams:

  •  CompTIA A+ Exam 901 – Focuses on hardware 170$ US
  •  CompTIA A+ Exam 902- Focuses on software 170$ US

Total examination costs =330$ US (varies depending on location).  

To become  CompTIA  A+ certified students must successfully complete both exams

Time

lukas-blazek-263122-unsplash

You have 90 minutes to complete the CompTIA A+ Exam.  However, once the exam has started there are no breaks given unless there is a malfunction with the test.

Questions

evan-dennis-75563-unsplash

The CompTIA A+ exam has a maximum of 90 questions.  There is a myriad of questions types such as:

  • Multiple Choice
  • Multiple Answer
  • Drag & Drop
  • Simulation

Passing Score

julian-lozano-549084-unsplash

The passing score for each test is as follows:

  • 901- 675 out of 900
  • 902- 700 OUT OF 900

Recertification

sydney-rae-408416-unsplash

Students must recertify every three years.  Students can waive recertification by enrolling into CompTIA’s continuing education for an annual fee.  Another route to recertification is by simply acquiring a higher level certification.  For example, a student who is A+ certified, can get security+ certified as well.  In doing so they not only obtain the Security+ certification but also renew their A+ certification.
