A good recertification policy ensures that employers who make hiring and management decisions informed by a certification have a relevant, up-to-date tool. Over time, technology changes, so it's important to gauge whether your knowledge and skills have kept pace.
It's also important that you use your certification skills regularly enough to keep them sharp. Inactivity with a technology can mean that you're unfamiliar with a newer release and might not have retained skills on an earlier one.
Until the release of Red Hat® Enterprise Linux® 6, a certification holder remained current for 2 major releases. For example, if you earned your Red Hat Certified Engineer (RHCE®) credential under Red Hat Enterprise Linux 3, you remained current until 60 days after the release of Red Hat Enterprise Linux 5.
With the release of Red Hat enterprise Linux 6, a new 3-year calendar-based current window is in effect for Red Hat Certified System Administrator (RHCSA) and RHCE certifications earned or recertified on Red Hat enterprise Linux 6. If an RHCSA or RHCE earned on Red Hat enterprise Linux 6 passes a higher-level exam during that 3-year period, Red Hat will reset the 3-year current window to the date of the most recent exam.
These changes to the current window ensure that employers can count on Red Hat-certified individuals to be able to demonstrate the skills needed for today's technology.
