“…Apart from cognitive ability (e.g., Deary et al, 2007;Laidra et al, 2007;Li et al, 2019;Roth et al, 2015), it is well established that socioeconomic status (SES) is intimately linked to academic achievement such as grades and scholastic assessment tests in a variety of national and international contexts (e.g., Sirin, 2005;Tan, 2015;Kim et al, 2019), inclusive of Sweden (e.g., Gustafsson & Yang Hansen, 2018;Myrberg & Rosén, 2009;Wiberg & Rolfsman, 2021).
