People are hiring tutors in almost any area in which skills can be taught and acquired: academic subjects and computer use, athletic skills and hobbies. While most independent tutors have students come to their homes, some go the clients' homes or may be able to use space at the students' schools, or if they're helping students with a sport, they'll use the appropriate kind of field or facility.
Academic tutoring has been in particular demand because of the increased expectations placed on high school and even grade school students. As one tutor told us, "What used to be taught in college in the old days is now taught in high school." Crowded classrooms don't enable the individual attention many students require, and parents are finding that their children are not sufficiently prepared for college nor for the entrance examinations necessary for admission. They realize their children often need more personalized attention than they can get from classroom instruction.
