These guidelines were prepared to assist Idaho schools in developing policies and procedures for internal systems to respond to adolescent chemical use. Response to chemical health issues is discussed in terms of the school's role, need for policy, confidentiality issues, and administrative coordination of efforts. Staff training, primary prevention, early identification, crisis intervention, and aftercare are also discussed, as are the benefits of outside consultants. A section on legalities and responsibilities under Idaho law includes the responsibility and liability of school officials. The appendices contain suggested guidelines for selecting consultants, a list of prevention education providers and private providers of substance abuse intervention and rehabilitation services, community resource information, school law enforcement relationship guidelines, a student assistance process development flowchart, and a student assistance program intervention flowchart.
