What are the ISTQB exam dates? ISTQB exam dates can be selected by you because there are not set dates for ISTQB exams. Follow these steps to choose your ISTQB exam date and time: Purchase an ISTQB exam voucher – it is valid for 365 days. Log into “My Account” and click the button under Schedule My Exam. Choose from the open dates and times within those 365 days. If you need to change your exam date or time, you can do so without any additional cost by making the change at least 72 hours before your exam. Simply log into your account once again and click the button under Schedule My Exam. If you have questions, please contact us.
