<p>I would check with the school to see whether this will be counted as an excused or unexcused absence.</p>
<p>In some school systems, a week’s unexcused absences could prevent a student from graduating on time. In the area where I live, there is a limit on unexcused absences; if you exceed it, you have to repeat the grade. This has mostly caused issues for students who wanted to go to grandparents’ funerals in foreign countries, but it could apply to a situation like your daughter’s as well. Your school system might have the same problem.</p>
<p>Also, I wonder whether the professor has considered problems that might arise because of the student’s age. Even if she is 18, she might be too young to rent a hotel room in the Eastern European city, for example. Has this professor taken high school age students to this city before? I’m wondering whether it might be a good idea for an older family member to accompany the student to avoid hassles of this sort.</p>
