„Education systems in which teachers with a specialisation in supporting low-achieving students ('remedial teachers') are involved in learning support provision have, on average, lower percentages of low achievement among fourth grade students in mathematics. The role of specialised teachers varies from coordinating learning support provision, developing individualised learning programmes and communicating with parents to actual teaching.”
