The equalisation system does not have the ambition to completely equalise the economic situation in all municipalities, conditional on socio-economic status, but to reduce major differences. Although there is evidence indicating that homework may improve student achievement (Falch and Ronning, 2012), homework also has distributional effects, since students from a high socio-economic status typically receive more help with homework than students from a low socio-economic status. It may be particular challenging for immigrant parents to support their children with the homework.
