To receive Linux® certification you should begin by ensuring you have the knowledge needed to pass Linux® certification exams. You will then need to take some type of certification exam or exams, depending on the type of certification and level of experience you are looking to establish. These are offered by a number of different providers, though you should try to ensure you are testing with a group that is established and respected within the information technology (IT) industry. Once you are certified, you will be able to use that certification on your resume, often as a way to demonstrate an established standard for knowledge and performance.
Linux® is a system of open source software programs and projects that are developed and utilized by thousands of users all across the world. It is a UNIX® based system and can often be found in many major network infrastructures, such as Internet networks and major server setups. Linux® itself can be utilized in anything from small personal devices like wireless phones and digital watches to major supercomputers and mainframes.
In order to establish someone’s proficiency with Linux®, most people undergo some form of Linux® certification that provides prospective employers with some idea as to how much training or understanding someone has of Linux®. The major problem with this, however, is that there is no single industry standard as to what is required to gain Linux® certification. This means that simply having the certification is often not enough; since many people may be certified by a disreputable group or simply state they have the certification without really being able to back it up.
To receive Linux® certification and be sure that you do not waste your time or money on a certification that will not be respected or demonstrate real knowledge, do some research behind any certifiers before paying to take their tests. You may be able to take the tests over the Internet, but some certification centers require testing in person to prove you are the one taking the exam. The Linux® Professional Institute® (LPI) is one group that strives to provide competent testing and authentic Linux® certification.
You might also look into certification from specific software developers, such as the Red Hat® Certified Engineer (RHCE) certification offered by Red Hat Inc®. These types of Linux® certification may cost more than others, and can be limited by the affiliation with a major company, but they can also provide you with certain advantages such as brand name recognition and established industry standards. Receiving your Linux® certification can also be a hefty investment, as full certification may require several tests at various levels.
