Truancy is any intentional, unjustified, unauthorized, or illegal absence from compulsory education. It is a deliberate absence by a student's own free will and usually does not refer to legitimate excused absences, such as ones related to medical conditions. Truancy is usually explicitly defined in the school's handbook of policies and procedures. Attending school but not going to class is called internal truancy. Some children whose parents claim to homeschool have also been found truant in the United States.
