David Wade Risner, Director of Pupil Personnel at PHM, developed and implemented the drug testing policy. In his deposition, he averred that students participating in extracurricular activities and student drivers, if receiving a positive test result, may be subject to exclusion from any extracurricular activities and/or to revocation of parking privileges. However, he claims that they will not be subject to suspension, expulsion, or any discipline in connection with the academic school day for receiving a positive test result. See R.37 at 2.
The policy also discusses the testing procedure. Students are selected on a random basis without advance notice. First, they fill out paperwork and list any over-the-counter or prescription medications that they are taking. Next, they remove all outer garments and leave all bags and purses outside the collection facility. Then they are asked to wash their hands with water only, and the collector checks the stall visually for anything unusual, flushes the toilet, and treats the water with dye. While the student is producing the sample, the collector remains outside the facility and notes any unusual circumstance, behavior, or appearance of the student or of the specimen. Also, the collector checks the specimen for signs of contamination and notes the temperature of the bottle. Both the student and the collector sign the ehain-of-custody form.
The test checks for the presence of alcohol, nicotine, and any drug listed as a controlled substance. The results will be provided to the designated school official who always shares the results with the student’s parents. For the first and-second positive test, the result is shared with the parents and an attempt is made to provide evaluation and/or treatment. For the third positive test, the parents are required to pay for the test. Again, the results are shared with the parents and the school, and an attempt is made to provide evaluation and/or treatment.
As to confidentiality, the policy states that the results will always be shared with the student and a parent or guardian. Thereafter, information regarding the positive test result will be shared on a “need to know” basis with school staff. Under the program, any staff member, employee, coach, or sponsor of PHM with knowledge of a student’s positive test result shall not reveal the information to anyone other than the student or the parents unless under order of a court.
B. District Court Opinion
As mentioned above, several PHM students filed suit against the School. In their suit, they alleged that the School’s suspicionless drug testing of students involved in extracurricular activities and of student drivers violated their Fourth Amendment rights against unreasonable searches and seizures.
In response to the School’s motion for summary judgment, the district court followed this circuit’s opinion in Todd v. Rush County Schools, 133 F.3d 984 (7th Cir.), cert. denied, 525 U.S. 824, 119 S.Ct. 68, 142 L.Ed.2d 53 (1998), which allows random drug testing for students participating in extracurricular activities, and upheld the . extracurricular activities prong of PHM’s policy.
For the students who possessed parking passes and who were subject to the random drug testing, the district court stated that, except for those students close enough to school to walk and “a limited category of students otherwise,” PHM provides public transportation. Therefore, students do not have a compulsion to drive themselves to school. The court explained that students sign a consent form in exchange for the privilege of parking on school premises and that the safety issues evolving from students driving to and from school while under the influence of illegal substances justifies the testing.6
