While you can certainly take into consideration whether heavy drinking is pervasive, don’t penalize a school for heavy ER visits. There will be some alcohol at basically every college and all students should be comfortable calling for emergency services when a person drinks or uses drugs and needs medical attention. Deaths occur when students are afraid they’ll be suspended, expelled or arrested for underage drinking. No one should die because they drank too much.
So my point is, check the level of partying at prospective colleges. but more importantly check that there are Good Samaritan rules in place. It could save YOUR child’s life.
