Are you sure it isn't a "only in Ukraine" moment. If I have passed the test, then I was the person who wrote the answers, so therefore I sat the test - I attended the test.
But yes, the (attendance) roll has to be marked and verified.
I'd go for V3 as the answer: You'll receive the certificate/ The certificate will be available, once the instructor (or 'subject co-ordinator) approves or verifies the attendance roll.
Usually the teacher supervising the test has a boss, a subject co-ordinator (they did at college) who oversees that subject/s. So, the subject co-ordinator checks that the test was run properly, and that all those particular students actually sat the test.
