What occurs if a license's expiration date is changed?

When a license's expiration date is changed, the correct outcome is that license fees are prorated based on the validity period. This means that if the expiration date is extended or moved, the fees associated with the license are adjusted proportionally to reflect the new duration of the license’s validity. This ensures that the license holder is not unfairly charged for a full term when they are receiving a license for a different length of time, promoting fairness in the licensing process.

In contrast, the other options do not accurately describe what happens when a license's expiration date is altered. The renewal fee is not always full; the proration ensures fee equity based on the adjusted period. Additionally, a change in expiration does not automatically lead to automatic renewal of the license, nor does it necessitate additional training requirements for the holder. The proration of fees is a common practice in licensing systems to ensure that holders only pay for the time they are authorized to operate under that license.
