During a recent school trip by the regional band, Hahn is alleged to have visited a student's hotel room to share pizza with three female band members and a female alumnus who currently is a student at Kutztown University. There is no allegation that he engaged in any inappropriate behavior, but this kind of fraternization during a school trip is supposedly a violation of school district policy.
Hahn is considered a mentor to one of the female students with whom he shared pizza. While his behavior might be nothing more than an innocent mistake in judgment, I believe this investigation is appropriate.
Pennsylvania's Department of Education's Professional Standards and Practices Commission prohibits teachers from sexually harassing or engaging in sexual relationships with students, but this is inadequate to stop grooming. Many school districts now also bar teachers from entertaining, socializing or spending extra time with students so they don't forge an unprofessional relationship.
