Exam Details

Exam Format

Certification Exams are performance-based and Candidates will need to perform tasks or solve problems using the command line interface in their chosen Linux distribution. For exam security, Candidates are monitored by a proctor during the exam session via streaming audio, video, and screensharing feeds. The screensharing feed allows proctors to view candidates' desktops (including all monitors). The audio, video and screensharing feeds will be stored for a limited period of time in the event that there is a subsequent need for review.

Candidates must ensure they meet the System, ID, and Other Requirements for Taking the Exam.

The following choices of Linux distributions are offered for the Exam. Candidates will be prompted to select from one of these choices when registering for the Exam.

  • CentOS 6* (see upcoming changes for CentOS below)
  • openSUSE 13.1
  • Ubuntu 14.04

*Beginning July 21, 2015 at 19:00 UTC, the version of CentOS available for selection during purchase will be CentOS 7. If you want to select CentOS 6 for an Exam, you must register and pay for the Exam before July 21, 2015.

If you completed an Exam purchase before July 21, 2015 and wish to switch to CentOS 7, you must wait until July 22, 2015 to request a switch. Find out how to make a request to change distribution here.

System, ID, and Other Requirements

System Requirements:

Candidates are required to provide their own front-end hardware (laptop or workstation) with Chrome or Chromium browser, reliable internet access, and a webcam and microphone in order to take exams. Candidates do not need to provide their own Linux installation or VM; they will be presented with a VM in their browser window using a terminal emulator. Candidates should use the compatibility check tool to verify that their system and testing environment meet the minimum requirements.

Candidates are required to provide a means of photo identification before the Exam can be launched. Acceptable forms of photo ID include current, non-expired: passport, government-issued driver's license/permit, national ID card, state or province-issued ID card, or other form of government issued identification. If acceptable proof of identification is not provided to the exam proctor prior to the exam, entry to the exam will be refused. Candidates who are refused entry due to lack of sufficient ID will not be eligible for a refund or rescheduling.

Other Requirements

Candidates should also be sure to review Policy and Terms for Certification and Exams.

    How to Renew Certifications

    Linux Foundation Certifications are valid for 2 years. Candidates may renew Certification by completing one of the renewal requirement options below. Renewal requirements must be completed prior to the expiration of a Certification. Any renewal requirements completed before the Renewal Date of a Certification will not carry over to the new period.

    Options to meet Certification renewal requirements:

    • Achieve (or renew) a higher-level Certification. When using a higher-level Certification to extend a lower-level Certification, the expiration date of the lower-level Certification will be extended to match the expiration date of the higher Certification. For the lower-level certification, the date on which the expiration date is extended becomes the Renewal Date. (For example, if Certificant has one year left on their LFCS Certification and earns LFCE Certification, then both their LFCS and LFCE certifications will be made to expire 24 months from the date that LFCE certification was achieved. The date on which LFCS Certification has its expiration date extended becomes the Renewal Date for the LFCS Certification.)
    • Complete at least 16 hours of Continuing Education. Certificants must complete at least 16 hours of approved Continuing Education activities before the expiration date of their Certification and will need to submit an Application for Continuing Education Credit to receive credit towards renewal. Continuing Education credits will be applied to the highest-level of Certification that is current for a Candidate. The 16 (sixteen) hours of activities must align to at least four (4) of the Domains for that Certification. Certificants who complete the necessary Continuing Education requirements on time will have their applicable Certification extended for an additional 24 months on the expiration date of their Certification. (For example, if Certificant’s LFCS Certification expires on January 25, 2015 and Certificant completes Continuing Education requirements on October 1, 2014, their LFCS Certification will be extended for an additional 24 months on January 25, 2015. The expiration date for Certification is extended to January 25, 2017 and January 25, 2017 becomes the Renewal Date for that Certification.)
    • Approved Continuing Education activities include:

      • Advanced training courses from The Linux Foundation’s Developer and/or Enterprise curriculum (designated with a Linux Foundation course code of 300 or higher, e.g. LFD320 or LFS426).
      • Approved training from another provider, e.g. from a Linux Foundation Authorized Training Partner or from an established Linux training provider such as Red Hat, Oracle, IBM, HP, SUSE and other similar programs.

      Certificants may complete any combination of approved Continuing Education activities to reach the number of hours required for renewal.
