What happens if I fail a test?
As with every Cloudera test, you are given a score report that informs you of your overall score and how you scored on each section of the test. From this score report, you will know which areas of the test you need to study before scheduling to take the test again.Candidates who fail a test must wait a period of seven (7) calendar days, beginning the day after the failed attempt, before they may retest for the same test. There is no limit to the number of retakes a candidate may attempt. There are no discounts for retake exams.
I passed, but I’d like to take the test again to improve my score. Can I do that?
Retakes are not allowed after the successful completion of a test.A test result found to be in violation of the retake policy will not be processed, which will result in no credit awarded for the test taken. Repeat violators will be banned from participation in the Cloudera Certification Program.What do I get when I pass my tests?
You receive a printed score report at the test center. This is provisional until validated by Cloudera. You may use this to show you completed the exam but it is not proof of certification. If you pass and your score is validated by Cloudera, you receive an email within 7-10 days from certification@cloudera.com. The email includes:How do I verify a certification?
Email certification@cloudera.com with the verification request. Include your name, email used at the time of the certification, Pearson VUE Cloudera testing ID, and the test date. We are working to launch a verification portal to automate this process.In what languages are the tests delivered
We release all exams in English and Japanese. Language release dates are specified on the individual test pages.
