Over the last two decades, reading has shifted from taking place on paper to, increasingly, screens. As digitalisation spreads, there have been growing concerns about unbalanced access to new types of resources between socio-economically advantaged and disadvantaged students. PISA 2018 results show that while disadvantaged students are catching up in terms of access to digital resources, their access to cultural capital like paper books at home has diminished, and the socio-economic gap has been persistent over the last two decades. This policy brief draws education stakeholders’ attention to this issue and provides evidence for the discussion of equity in education by examining how access to books at home is related to students’ prevalent mode of reading books, their performance in reading and their enjoyment of reading.
