What you need to know

Preparation

Red Hat encourages you to consider taking Red Hat System Administration I (RH124) and Red Hat System Administration II (RH134) to help prepare. Attendance in these classes is not required; you can choose to take just the exam.

While attending Red Hat classes can be an important part of your preparation, attending class does not guarantee success on the exam. Previous experience, practice, and native aptitude are also important determinants of success.

Many books and other resources on system administration for Red Hat products are available. Red Hat does not endorse any of these materials as preparation guides for exams. Nevertheless, you may find additional reading helpful to deepen your understanding.

Exam format

The Red Hat Certified System Administrator (RHCSA) exam is a hands-on, practical exam that requires you to undertake real-world tasks. Internet access is not provided during the in-person exam, and you will not be permitted to bring any hard copy or electronic documentation into the exam. This prohibition includes notes, books, or any other materials. For most exams, the documentation that ships with the product is available during the exam.

This exam can also be taken virtually as part of our remote testing format. Find out more about remote exams to see if this is the right choice for you.

Scores and reporting

Official scores for exams come exclusively from Red Hat Certification Central. Red Hat does not authorize examiners or training partners to report results to candidates directly. Scores on the exam are usually reported within 3 U.S. business days.

Exam results are reported as total scores. Red Hat does not report performance on individual items, nor will it provide additional information upon request.

You are eligible for one exam retake if you are unsuccessful on your first attempt. For more information please read our Training Policies page
