A tutor can be a professional educator with certification, a fellow student, or a person with demonstrated expertise in an area of study. Tutors may be found in a school setting, but are often independent entities. Tutors have existed throughout history, mainly in the employment of the upper class and royal families. Today, tutoring services can be found for almost any subject for students of all ages, in the form of test prep centers, learning centers, private services, and online services.
