In a school district in California, Latinos demanded and got a prom separate from the Anglos. I remember the story from a couple of years ago, but I have forgotten the details.
Social separation is hard to get away from in areas where there are two large groups with a distinct difference between them. The differences take time to be resolved and careful solutions by those in authority.

In my city, more and more students are entering private, or charter schools. These schools are encouraged by the Provincial government. Separation is by income level and intelligence quotients, but since immigrants generally have smaller incomes as well as more difficulty in passing entrance requirements, a high degree of racial separation results. Catholic and non-Catholic students have had separate schools for many years. As would be expected, the non-Catholic public school system is suffering the most from loss of students.

Segregation of one type or another is alive and well.
