    RHCE Certification:

    RHCE and RHCT Exam Preparation Guide

    Performance-based Exams

    The Red Hat Certified Engineer (RHCE) and Red Hat Certified Technician (RHCT) exams are performance-based evaluations of Red Hat Enterprise Linux system administration skills and knowledge. Candidates perform a number of routine system administration tasks and are evaluated on whether they have met specific objective criteria. Performance-based testing means that candidates must perform tasks similar to what they must perform on the job.


    Authorized Training Partners


    Only Red Hat and Red Hat Certified Training Partners administer the RHCE and RHCT exams. Prospective candidates should exercise due diligence when purchasing a seat in an RHCE or RHCT exam from a provider other than Red Hat itself. They should verify that the provider is, in fact, an authorized training partner in good standing. Logic is an authorised Training partner for many years.
    Official scores for the RHCE and RHCT 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 three (3) US business days.
    Exam results are reported as section scores. Red Hat does not report performance on individual items, nor will it provide additional information upon request.


    Preparation for the RHCT and RHCE Exams


    While attending Red Hat's classes can be an important part of one's preparation to take the RHCE or RHCT exam.Many books and other resources on system administration for Red Hat's OS products are available.
    Format of the RHCE and RHCT Exams
    The RHCT exam is a subset of the RHCE exam delivered separately. Effective May 1, 2009, this exam is a single section lasting 2.0 hours. Previously, it had been two sections lasting a combined 3.0 hours. Consolidation and reorganization have made it possible to cover the same material more efficiently.
    Effective May 1, 2009, the RHCE exam is a single section lasting 3.5 hours. Previously, it had been two sections lasting a combined 5.5 hours. The content has be consolidated and reorganized into a single section in which time is used more efficiently. The RHCE exam consists of RHCT components (essentially the RHCT exam) plus RHCE-specific components. It is possible to earn RHCT in an RHCE exam if one has met the RHCT requirements but not the RHCE ones.
