There is no country or economy participating in Pisa 2012 that can claim that all of its 15-year-old students have achieved a baseline level of proficiency in mathematics, reading and science. Poor performance at school has long-term consequences, both for the individual and for society as a whole. Reducing the number of low-performing students is not only a goal in its own right but also an effective way to improve an education system's overall performance – and equity, since low performers are disproportionately from socio-economically disadvantaged families.Low-performing Students: Why they Fall Behind and How to Help them Succeedexamines low performance at school by looking at low performers' family background, education career and attitudes towards school.
