current interpretation

While students are present at a non-private public school, their rights to being searched are slightly different than if they were an adult being searched by a law enforcer/police officer. While a student is at school the teachers, officials, and principles are "in loco parientes" meaning the school faculty should take the place of the students' parents while they're kids are at school. Just like parents, the teachers shall be able to search students and their belongings with certain suspicion in an appropriate way. depending on the severity of the issue, and the potential harm the student could cause with whatever him/her are being searched for, the faculty should treat the problem and apprehend the issue with an appropriate amount of attention and handle it by its level of dangerousness to the student body in an individual level and in sense of the amount of harm it can cause the student body as a whole. some schools in different areas of the USA handle this in different ways depending on the amount of problems with students and contraband in the schools therefore having different policies on student searches to keep other students in their opinion "safe", but do their policies follow the fourth amendment and are they necessary in all situations?
