I completely agree.

One of the reasons I replied is to show that, regardless of the stated purpose of the survey, the FERPA rules appear to favor of the school even if they should decide to use the survey for other purposes. From my reading, FERPA may very well not protect these kids from a school's decision to ultimately convey this information to police.
