The correct answer is school systems refused to honor the ruling and contiued to operate seperate but equal schools until 1977.
Even though the Brown vs. Board of Education decided that separate but equal facilities for white and black students violated the 14th amendment of the US Constitution, many Southern states chose to ignore this ruling. For example, Central High School in Arkansas refused to follow this ruling until the national guard was called in and forced the integration of this school. Other schools and universities (like the University of Alabama) took a similar stance against integration, refusing to allow black students to enter unless forced to by the federal government.
