The Office of National Drug Control policy has put together this guide to assist educators, parents, and community leaders in determining whether student drug testing is appropriate for their schools. The aim is to provide anyone considering a drug-testing program in his or her community with a broad understanding of the issue and solid, up-to-date information on which to base a decision. The guide explains, generally, what drug testing is all about, who pays for it, who does the testing, what it tells about an individuals drug use, and equally important, what it does not reveal. The booklet describes what services should be in place for communities to deal effectively with students who test positive for drugs, and it also offers case histories showing how several schools used testing to address their drug problems. Their experiences may help others determine whether testing is right for their communities. (GCP)
