This is exactly what the resorts I've been to do. Dives are free (All inclusive, Couples Jamaica) but if don't have a dive book with a signed off dive in the last year it is 50$ for a refresher/skills test.
I've normally felt really safe on these but once there was way to many people for them all to be babysat and the group actually got split up due to 'issues' that the following guide had to help with.
