Schools around the U.S. have seen a huge increase in cheating over the past 20 years. Students placement test scores have gone down close to 9% in the past 20 years. And many believe that this is caused by students cheating their way through daily assignments and tests.
In most cases of cheating it is two people working together, this can be through passing answers or sharing photos or even doing your friends assignment. All these can result in a suspension, Detention, or a zero on your assignment.
Plagiarism is the practice of taking someone else's work or ideas and passing them off as your own. This is seen a lot when students are writing essays many students take words and ideas from others but where you get into trouble is when you decide not to give that person credit for their work. The penalty for this varies in a school setting you will most likely receive a zero and can be given other punishment. If this occurs in college you could be at risk for more harsh punishment like the possibility of getting kicked out of school.
