SES Qualified Source Test Individual and Observer (QSTI /QSTO) Program

Updated Examination Policy

For the online exams, candidates will be permitted to make changes to an existing LOP appointment no less the 24 hours in advance of the scheduled appointment, be it a reschedule or cancelation of the appointment. Candidates may do so by accessing their confirmation email, received after scheduling, or their Notice to Schedule email. Once the rescheduling request is submitted, they will automatically receive an email of confirmation of their new appointment time. Candidates who do not reschedule or cancel the appointment will need to test at the scheduled time of the exam. Should they not for the exam, they will be considered a no-show and have their eligibility canceled. They will have to reapply to sit for the exam, paying the registration fee again.
