Six-month renewal window
You can take the renewal assessment any time during your six-month eligibility window, via Microsoft Learn. Once you pass, your certification will be extended one year from the expiration date.
Assessments are short and unproctored
The assessments focus on recent industry and technology updates, so are shorter than the original exams. You can take the assessment as many times as you want as long as you pass before your certificate expires.
