The key to the Linux community is the openness of the technology. It is the strength and the foundation of the community. To create a successful certification program, that sense of community must be maintained and supported. As the corporate environment increases its support of Linux computing, there will be a corresponding demand for proof of experience. As we have seen other professional certifications become the benchmark for measuring a candidate"s qualifications, Linux certification will increase in demand as candidates compete for these jobs. The LPI exams were developed with the focus on principles and theories, rather than vendor-specific facts. LPI"s certification levels are being designed with the goal of establishing a candidate"s comprehension of the architecture of a solution, allowing the details of implementation to be covered by vendor-specific elective portions of their exams. There are three levels of testing currently planned, but they have not been named.
