While occasional school absenteeism may not be problematic, excessive absenteeism has shown to have a negative impact. Students with poor attendance records are found to be at a disadvantage both academically and socially. Compared to their peers, these students are more at risk of academic under-performance and early school leaving. They are also at risk of having more restricted opportunities in terms of further education and employment, and are likely to experience social and emotional problems in adulthood. Missing school can be a habit-forming behavior and can be challenging to deal with despite growing awareness of the causes of absenteeism.
