In the United States, the term tutor is generally associated with one who gives professional instruction (sometimes within a school setting but often independently) in a given topic or field.
A large portion of tutors are academic and work for high schools, colleges, or universities. Tutors are usually very well-versed in the subject they are teaching and are able to effectively convey that knowledge to their students. Good tutors provide a friendly and productive learning environment for their clients.
