According to Wikipedia, desegregation busing is:
Desegregation busing in the United States (also known as simply busing) is the practice of assigning and transporting students to schools so as to redress prior racial segregation of schools, or to overcome the effects of residential segregation on local school demographics.
In an article on presidential hopeful Joe Biden's opposition to busing at the time, they write:
It was more than four decades ago as a battle raged across the country -- and in Congress -- over sending white students to majority-black schools and black students to majority-white schools often far away from their own neighborhoods.
What policies are used to prevent segregation in education today? One example that I can think of, in addition to busing, is setting racial quotas (e.g. forcing that schools have at least a certain % of people from racial minorities), though I'm not sure if that's used in any country right now.
I know this might seem broad, but most of the things I have found relate to the United States and date back to the previous millennium. Please note that I'm asking for current examples. Please include a detailed description of the desegregation policy in your answer.
