Minimum charge by 1/2 hour, in 1/2 hour increments.

This will also serve to keep the phone calls focused and discourage multiple interruptions.
...but only if the teacher calling your wife knows how the school is being charged for her time. In most cases, your wife would be billing the school directly, and the teacher calling for help will never see a bill or know how your wife is charging---unless school administration tells the teacher to stop calling because it's so expensive!
