During Pennsylvania recertification, a school bus driver fails the skills examination three times. What does PennDOT say must happen?

1. The current School Bus Endorsement card must be surrendered and the driver must reapply for an S endorsement learner's permit and complete all new-driver training requirements
2. The driver may keep operating until the next four-year cycle
3. Only the failed maneuver must be practiced for 30 minutes
4. The driver may switch to a smaller bus without retesting
