Linux Foundation Certified Engineer (LFCE)

The Linux Foundation Certified Engineer exam is designed for the Linux engineer looking to demonstrate a more advanced level of Linux administration and engineering skill.


The Linux Foundation Certified Engineer is the ideal certification for the Linux engineer with at least three to five years of Linux experience. It is designed for the engineer looking to demonstrate a higher level of skill set to help qualify for a promotion or land a new, more advanced job. The exam is performance-based on the command-line, and includes items simulating on-the-job scenarios.

There are no pre-requisites for this exam.

Domains & Competencies

The Linux Foundation worked with industry experts and the Linux kernel community to identify the core domains and the critical skills, knowledge and abilities (“competencies”) applicable to each certification. Performance-based exams were then developed based on the competencies that were identified.
