A+ Certification, sponsored by CompTIA, is one of many IT certifications currently available. The certification program is designed to provide an individual with sufficient skills and knowledge to obtain an "entry level" position as a PC Technician.
Whilst this may not be the ideal job for everyone, one of the main benefits of the A+ Certification Programme is that it introduces you to a wide range of subjects, both hardware and software, that can give you a good basic understanding of how PC systems work and this understanding WILL assist you in any Information Technology studies you may be considering.
