If you have used one of the ORS4 licensing exemptions (1409, 1410, 1411 and 1412) please note that when revalidating the rating/class by proficiency check or check with instructor, the expiry date will be 12 months or 24 months (dependent on the rating/class) from the month when the check was taken.
ORS4 extensions of validity are not part of the normal revalidation process, and this would be in non-COVID-19 times be a renewal.
