In Model 1, we found a significant positive main effect of ethnicity [ b = 48.20, SE = 6.29, t (656) = 7.67, p < 0.001] and a marginally significant negative main effect of percentage of Turkish-origin students [ b = −0.57.45, SE = 31.76, t (656) = −1.81, p = 0.07], but unexpectedly no cross-level interaction effect on students' performance ( p = 0.81; see Table 2 ).
