Final answer:
A student permit can become invalid if the student violates the conditions of the permit, no longer meets the requirements, or if it expires.
Step-by-step explanation:
In order for a student permit to become invalid, there are several circumstances that can apply. One common reason is if the student violates the conditions or terms of the permit. This may include engaging in illegal activities, academic dishonesty, or disciplinary issues.
Another reason a student permit can become invalid is if the student no longer meets the requirements or qualifications for the permit. For example, if a student's grades drop below a certain level or they fail to maintain a necessary GPA.
Lastly, a student permit may become invalid if it expires. Permits usually have an expiration date, and if the student fails to renew it in time, it will no longer be valid.
