  • How to register and prepare for Jenkins Certification exams

    You should take a look at our Certification Guide. This guide walks you through the key need-to-know about Jenkins Certifications.

    Preparation and many Jenkins courses are also available as self-paced through CloudBees University.

    Certification courses may also be offered during the annual DevOps|Jenkins World event.

  • I see new certifications available, but I already scheduled one of the older ones. Can I change which one I want to test for?

    Yes! For instance, perhaps you are scheduled to take the CCJE exam, but you want to switch to the new CloudBees CI Essentials exam. No problem!

    As long as you are more than 48 hours from your scheduled exam, simply cancel the old one and you will receive a refund. You can then schedule the new exam you want.
    If you used a voucher, you can still use the same voucher code for the new exam (it does not get used up until you actually take an exam).

    Here are the steps:

    • Go to

    • Log in with the credentials you received via email when you initially scheduled.

    • Go to My Assessments.

    • Select “Reschedule/Cancel for the exam you no longer want.

    • Choose Cancel, Submit.

    • Select Register for an Assessment and schedule the one you want.

  • Help, my self-paced Virtual Box/Vagrant environment is not working!

    Most troubleshooting tips can be found within your class’s lab troubleshooting guide. Check for the section of your course called “Install Lab Environment”

    and then browse to “Troubleshooting”

    While CloudBees produces self-paced lab environments that can be hosted locally for students, CloudBees supports these for non-CloudBees customers as “Best effort” support, meaning we will provide initial triage and support to replicate problems encountered. However if the issue is environmental or not widespread, CloudBees may not be able to immediately resolve. Most labs can be followed along with hosting your own local environment as well by downloading Jenkins from

  • When following the “Install Lab Environment” instructions for a training course, nothing happens when you run the command vagrant up. The command line exits without any output or error, or just hangs.
