“…Successful identification of the dropout risk factors enables us to calculate the likelihood of school leaving among students affected by those factors. For example, there is more chance that a student with the history of absenteeism and grade repetition (Lee & Burkam, 1992;, an underachieving student (Bryk & Thum, 1989) or a student who has somehow alienated from school life (Finn, 1989;Hammond, Linton, Smink & Drew, 2007;Wilson, Tanner-Smith, Lipsey, Steinka-Fry & Morrison, 2011;Lee & Burkam, 2003) will leave school at a certain point. At the same time, many studies point out that students who enrol in poorer schools and are taught by less qualified teachers often face a decrease in academic achievements and have fewer chances for further education (Aikens & Barbarin, 2008;Hanushek, Kain & Rivkin, 2009;Hattie, 2009;Hidi & Harackiewicz, 2000;Ingersoll, 1999).…”
