Tutoring can be an essential part of a developing childs life. Some children may not do as well in a large class or group learning environment, or perhaps just needs a little more one on one attention. So for those who may need this, tutoring is most definatley an option. Tutoring is a one on one experience that enables the pupil to get all the attention that he or she deserves.
Now this is not to say that tutoring is solely for children, but it is so crucial in children to ensure that they get strongly rooted in the subject they're struggling in. Tutoring younger children, and high school children is usually done by someone just a bit older, say a university student, and in university tutoring it may even be a peer tutoring.
Tutoring is nothing to be ashamed of, if anything, tutoring is something to be proud of. To be able to admit that you may need a litle more help than is regularily provided is an admirable thing.
