The RHCSA certification is designed for experienced Red Hat administrators and is required by some organizations to meet U.S. Department of Defense Directive 8570. It's also a prerequisite credential for the Red Hat Certified Engineer (RHCE).

Red Hat recommends three training classes to prepare for the RHCSA certification. The Windows admin classes are Red Hat System Administration I (RH124) and Red Hat System Administration II (RH134). Candidates may also take a Linux/UNIX admin class — RHCSA Rapid Track Course RH199 — to prepare for the RHCSA exam.

To obtain RHCSA certification, candidates must pass the 2.5-hour RHCSA Exam (EX200).

With the majority of Fortune 500 companies currently using Red Hat open source solutions, the value of IT professionals well-versed in Red Hat Linux technologies has long been recognized. Trained Red Hat professionals are a key ingredient to the successful creation and maintenance of Red Hat solutions that deliver enduring value. Regardless of the type of Red Hat technology deployed, there is a consistent, established ongoing requirement for IT professionals qualified to server as administrators, system engineers and architects.
