Establishing whether the student's consent was voluntary can be difficult, and the burden is on the school officials to prove voluntary consent. If a student agrees to be searched out of fear or as a result of other coercion, that consent will probably be found invalid. Similarly, if school officials indicate that a student must agree to a search or if the student is very young or otherwise unaware that he has the right to object, his consent will also be held invalid. School officials may find it helpful to explain to students that they need not consent to a search. In some cases, standard consent forms may be useful.

If a student is asked to consent to a search and refuses, that refusal does not mean that the search may not be conducted. Rather, in the absence of consent, school officials retain the authority to conduct a search when there are reasonable grounds to justify it, as described previously.

Special Types of Student Searches

Schools with severe drug problems may occasionally wish to resort to more intrusive searches, such as the use of trained dogs or urinalysis to screen students for drug use. The Supreme Court has yet to address these issues. The following paragraphs explain the existing rulings on these subjects by other courts:

SUSPENSION AND EXPULSION

A school policy may lawfully provide for penalties of varying severity, including suspension and expulsion, to respond to drug-related offenses. The Supreme Court has recently held that because schools "need to be able to impose disciplinary sanctions for a wide range of unanticipated conduct disruptive of the educational process," a school's disciplinary rules need not be as detailed as a criminal code.[ [17] Nonetheless, it is helpful for school policies to be explicit about the types of offenses that will be punished and about the penalties that may be imposed for each of these (e.g., use, possession, or sale of drugs). State and local law will usually determine the range of sanctions that is permissible. In general, courts will require only that the penalty imposed for drug-related misconduct be rationally related to the severity of the offense.

School officials should not forget that they have jurisdiction to impose punishment for some drug-related offenses that occur off campus. Depending upon State and local laws, schools are often able to punish conduct at off-campus, school-sponsored events as well as off-campus conduct that has a direct and immediate effect on school activities.
