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, 2015 becomes the Renewal Date for that Certification.)
- 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.
Approved Continuing Education activities include:
Certificants may complete any combination of approved Continuing Education activities to reach the number of hours required for renewal.
