What was the last public school to desegregate in the United States? What was the date of completion for that schools desegregation?
In 1979, the American Civil Liberties Union reopened the Brown suit, asserting that the existence of 13 racially segregated schools on either side of Topeka Boulevard violated the 1954 High Court ruling. Signing on to the suit was Linda Brown Thompson, who was 11 when her father and other black parents brought the first Brown suit.
After years of legal maneuvering, in 1993 a Federal court agreed with the A.C.L.U. Now the Topeka district is proposing to close some of the segregated schools, bus more of its 15,000 students across neighborhood lines and create magnet schools, all in the name of integration.
This information is also shown on the museum of Brown Vs Board of education which I recently visited and they have a board that say the last school was desegregated in 1994.
In 2016 a federal court ordered the Cleveland, Mississippi, school district to desegregate by consolidating its virtually all-black high schools with the high schools that were historically white.
The court’s ruling will result in the immediate and effective desegregation of the district’s middle school and high school program for the first time in the district’s more than century-long history.

Boston Massachusetts was the Last to desegregate. Mississippi was forced to desegregate at gun point before the Schools in the North were forced to by riots. The riots in Boston, 1974-1976, were Worse than any in Mississippi.
May 17th 1954 congress decided it was against some amendment and you can find the details on PBS website however from what I could find it seems that Mississippi as a whole did not want integrated schools but stuck out for freedom of choice and it's worth reading about how racist people were and it seems it eventually came about in Mississippi in 1970,
