The population in Cyprus, a recent European Union member, has become much more heterogeneous during the past decade. Here, we examine the attainment patterns of minority and native students enrolled in six secondary schools from different cities in Cyprus, and identify factors responsible for these patterns. The combination of examined factors has not, to our knowledge, taken place in previous studies. Findings confirm that ethnic minority groups perform significantly lower than native students. In terms of aetiology, we show that ethnic background, gender, parental education, parental occupation, generation status, absenteeism and school minority concentration have a significant effect on student attainment.
