Australien: „Being an immigrant has a uniformly positive effect on mathematics, reading, and science performance […] This ‚immigrant advantage‘ is likely due to two interrelated factors. First, Australia’s skills-based immigration policy prioritises immigrants with high levels of educational attainment and occupational status. Second, many immigrants, especially those who voluntarily migrate to multicultural immigrant countries such as New Zealand, the US, Canada and Australia, possess attributes and aspirations that promote school success.“
