From 1955 to 1970, an avalanche of over 5,000 pupils descended upon the York County school system. This influx was largely due to white flight as families moved from the neighboring cities of Hampton and Newport News to the county following the 1954 Brown v. Board of Education decision by the US Supreme Court that ordered racial integration of public schools. Cold War era expansions at military installations and defense industries in the area also brought some families in from out of state. Many changes to the schools came during that period as well. The year 1964 was the last year the school received funds from the district school levy. As of 1964, racial integration of YCSD schools began and the fall of 1967 marked the end of segregation. The James Weldon Johnson School, built on the same floor plan as YHS under the "separate but equal" emphasis during Segregation, became Yorktown Intermediate School.
