Exam Terms and Conditions

Exam Policies:

Certification Renewal / Recertification:

To keep your certification status, you have to go through recertification. Unless the detailed exam descriptions say otherwise, Google Cloud certifications are good for two years after you get them. Recertification involves retaking the exam and getting a passing score within a specific time frame. You can start the recertification process 60 days before your certification expires.

Retake Exam:

Google works hard to keep the certified user group secure by ensuring exam security and enforcing testing rules. Google Cloud is committed to carefully and consistently following program regulations. If you don’t pass an exam, you can retake it within 14 days. If you don’t pass the second attempt, there’s a 60-day wait before your next try. Failing the third time means you need to wait 365 days before attempting the exam again.

Cancellation and reschedule policy:

If you miss your exam, you won’t get your money back. If you cancel less than 72 hours before an onsite exam or less than 24 hours before an online exam, your exam fee is forfeited without a refund. Rescheduling within 72 hours of an onsite exam or within 24 hours of an online exam incurs a fee. You can set a new exam date and time by logging into your Webassessor account, choosing “Register for an Exam,” and selecting “Reschedule/Cancel” from the Scheduled/In Progress Exams option.
