Parental Research depends on the student/parent personalities and relationship.
Student may be overwhelmed with school/work/ECs etc. My D appreciated my research, she still made all the decisions, but I laid out affordable schools in her geographic preference range from home.
And this potential major/career seems to be one that colleges might vary widely in their course concentrations. I think it makes sense for a parent to gain a better understanding of the scope of a major/possible careers.
