Truancy is a term used to describe any intentional unauthorized absence from compulsory schooling. Children in America today lose over five million days of their education each year through truancy. Often times they do this without the knowledge of their parents or school officials. In common usage the term typically refers to absences caused by students of their own free will, and usually does not refer to legitimate "excused" absences, such as ones related to a medical condition. It may also refer to students who attend school but do not go to classes. Because of this confusion many schools have their own definitions, and as such the exact meaning of the term itself will differ from school to school and district to district. In order to avoid or diminish confusion, many schools explicitly define the term and their particular usage thereof in the school's handbook of policies and procedures. In many instances truancy is the term referring to an absence associated with the most brazen student irresponsibility and results in the greatest consequences.
Many educators view truancy as something much more far reaching than the immediate consequence that missed schooling has on a student's education. Truancy may indicate more deeply embedded problems with the student, the education they are receiving, or both. Because of its traditional association with juvenile delinquency, truancy in some schools may result in an ineligibility to graduate or to receive credit for class attended, until the time lost to truancy is made up through a combination of detention, fines, or summer school. This can be especially troubling for a child, as failing school can lead to social impairment if the child is held back, economic impact if the child drops out or cannot continue his or her education, and emotional impact as the cycle of failure diminishes the adolescent's self-esteem.
