†Not meeting the sampling requirements

As the table shows, the largest variance between schools is in Ger­
many (0.55), the lowest is in Slovenia (0.11). Next, Model 1 includes indi­
vidual SES at Level 1, and Model 2 incorporates school-level SES at Lev­
el 2. Both models use random intercepts and fixed slopes. Level 1 SES is
centered around the group mean and Level 2 aggregated SES is centered
around the grand mean in Model 2. The equations for these two models
are presented in Equations 2 and 3.
