Case
The teacher quietly walks over to the student and removes the test

During a 5th grade social studies exam, a teacher thinks that a student is cheating by looking at another student's paper across the aisle. The teacher quietly walks over to the student and removes the test. She tears the exam in half and drops it in the waste basket. Upon hearing about this situation, the student's parents are angry and demand a response from the principal in regards they view as an improper use of power. What ethical and legal considerations should the principal contemplate when addressing this issue?

Solution #1
The teacher should have stood between the students as a warning, she shouldn't have torn up the test.
Solution #2
There has to be some kind of proof, I have had students cheating. I move myself to be closer to them, then I allow them to finish their test. After class we have a conference about the cheating and they are allowed to defend themselves. I fortunately haven't had a student deny cheating, they always tell the truth. I think it has to do with not making a scene in the classroom and them having to save face. I then make them call their parents and explain to them what they did, then I get on the phone and talk to the parent and ask them if taking another test after school on their own would be a viable solution. This has worked in my favor so far.
Solution #3
The teacher should not have torn the exam up and thrown it in the trash.
Solution #4
The teacher should not be passive aggressive with any one student. The teacher should have allowed all of the students to finish the test and reviewed the results. The teacher could then address the issue with out being aggressive.
Solution #5
If the teacher had any suspicions then they should have talked to the student after class. Then grade the test and if the answers were similar then have each student involved retake the test at different times. Ripping up the test in front of the student, especially when you do not know the truth, is disrespectful and rude.
