Yes, middle schools in the State of New York were desegregated in 1966. School desegregation was decided for the entire United States in the famous case Brown vs. Board of Education in 1954, but even prior to that segregation was forbidden in the State of New York. (For a visual of pre-1954 segregation laws by state see map here.) Add to this the reality ...
