Every sixth student in Estonia does not complete upper secondary education during the nominal period and the share of early school leavers in Estonia is higher than in the EU on average. Low levels of education increase socio-economic vulnerability, reduce competitiveness in the labour market and create societal tensions and divisions. In order to prevent this, it is necessary that more young people complete secondary education. The project Alarm bell identifies risk factors for dropping out in upper secondary school based on data analysis. Based on these, an early detection system will be created in eKool (i.e., an online school management tool; eSchool in English), which provides students, parents, form masters and support specialists information about student's progression in their studies and enables interventions to be implemented in a timely manner.
