Reminder schedule

The 90/60/30-day system that stops lapsed certs

The most common reason certifications lapse isn't negligence — it's no system. This is the schedule used by trade shops that never miss a renewal.

-90

90 days out

Send first reminder to employee + manager. Verify renewal requirements haven't changed.

-60

60 days out

Send second reminder. Confirm employee has registered for or scheduled renewal course/exam.

-30

30 days out

Send urgent reminder. Escalate to ops manager if employee hasn't confirmed renewal progress.

Day 0

Expiration date

Flag in compliance dashboard. Employee may not be assignable to jobs requiring this cert until renewed.
