The concern over school absenteeism stems from both the determination of government authorities to ensure compliance with compulsory schooling and the correlation between this phenomenon and socio-educational inequalities of an academic nature (poorer performance, poorer academic achievement and higher dropout rates) and other kinds of problems (juvenile delinquency, alcoholism, drug addiction, unemployment, etc.). Numerous programmes, plans and protocols have been developed to improve school attendance among children and young people. However, little research has been conducted into their effectiveness. This evidence review seeks to provide an insight into the impact of programmes to combat school absenteeism, thereby pinpointing the factors conducive to improving attendance and ascertaining whether this varies according to the student profiles or circumstances in which they apply.
