The certification actually requires a passing score on two separate tests, currently numbered 901 and 902. The CompTIA A+ test undergoes almost constant revision, due to frequent innovations in the technology industry. The previously used test series (801 and 802) is no longer valid and may not be combined with a 900 series score to achieve certification.
The CompTIA A+ test content is driven by industry, not vendors. If a specific identifying word of a device or system is not mentioned in study materials, it does not mean you won’t be tested on that system or device. It just means that questions won’t cover things unique to that device.The two tests and the competencies they cover are:
Mobile Devices (17%)
Hardware and Network Troubleshooting (28%)
Windows Operating Systems (29%)
Other Operating Systems and Technologies (12%)
Software Troubleshooting (24%)
Operational Procedures (13%)
The percentages above indicate the portion of questions on that topic that usually appear on the CompTIA A+ 901 and 902 tests. You should note, however, that the questions within each test are not presented by topic in each section but are, rather, mixed.
Types of test items are multiple-choice (some with multiple responses possible), “drag and drop,” fill-in-the-blank (capital letters may count), questions that include an “exhibit,” and performance-based questions. Performance-based items include a given situation for which you need to find a solution. Most of these are near the beginning of the test.
CompTIA A+ certification is valid for 3 years from the test date and may be renewed by submitting proof of 20 continuing education credit hours in the field.
