Tutors are individuals that offer supplemental education. Tutors may work privately, in learning centers, or in schools.

There are tutors in elementary school, middle school and high school, as well as college. Tutors provide assistance and supplemental education in the subjects of all mathematical classes, and all levels of biology. There are chemistry tutors, English tutors for the language's many parts such as grammar, writing, and reading tutors for the interpretation of certain works of literature, tutors for history and foreign languages. Spanish tutors, French and German tutors, or any other language courses offered in the school's curriculum are usually available as well.

How tutoring works is the subject (or subjects) of difficulty are approached in a manner of breaking down the subject into parts and reviewing what is known about the subject, and then advancing toward completion of certain projects and class assignments. At the beginning of every tutoring session what will be covered is gone over and a goal for that session discussed. Overall, tutors should have a goal in mind as to what will be accomplished overall by their tutoring sessions, so that the result of tutoring sessions will be a thorough enhancement of knowledge in the given subjects.
