School's Interest

• The courts put the school's interest in student discipline and safety over a student's privacy rights. A reason why warrants are not needed to search a student's school locker is because he or she has less protection under the law. Students are in the care of the school, and schools are bound morally and legally to protect students from harm. Having to get a warrant to protect students is not necessary.
  
  

Reasonable Suspicion

• School officials can search student school lockers based on suspicious activity. Warrants are not need to search student lockers when facts or circumstances lead school officials to believe the student is involved with criminal activity. If a tip comes in that a student is selling drugs out of his school locker and a lot of unusual traffic is seen at that locker, officials can search the locker without a warrant.
  
  

Access

• Control of the lockers is held by the school. A warrant isn't needed to search a student's locker because the lockers are school property. The Fourth Amendment applies to a person's personal effects, and lockers are not deemed as student's personal effects.
  
  

Deter Crime

• Another reason why warrants are not needed to search a student's locker is schools need to deter criminal activity. School officials must maintain the right be able to inspect student lockers at any time. As long as students are aware of this they are less likely to have forbidden things in the lockers.
