The current study, based on a survey of 1799 parents, explored parental perspectives of school absence in relation to approved grades, challenges, demands and obstacles in education for children with autism spectrum disorder. The results revealed a relatively high rate of school absenteeism for reasons other than illness. Girls had higher rates of absenteeism than boys for short durations of absence. Absenteeism was primarily caused by a lack of teacher competence regarding autism and inadequate adaptation of teaching. There were no significant differences between genders in approved grades, but the rate of failure to achieve approved grades was approximately 50%. The most common form of educational support was support from special needs teachers and adapted pedagogy.
