Does “in loco parentis” mean “don’t tell the parents”? From NYT:

Federal privacy and antidiscrimination laws restrict how universities can deal with students who have mental health problems.
For the most part, universities cannot tell parents about their children’s problems without the student’s consent. They cannot release any information in a student’s medical record without consent. And they cannot put students on involuntary medical leave, just because they develop a serious mental illness.
