Particularly due to San Carlos' proximity to San Francisco, which had prompted social activism stemming from the
Summer of Love, San Carlos High School experienced changes in the early 1970s. In the 1969–1970 school year, students participated in moratoriums, electing to stay home from school every 15th of the month, allegedly in protest of the Vietnam War. Several years later, the Supreme Court ruled on the use of busing to achieve racial integration at schools, bringing change to the student makeup at San Carlos High School, which, due to the composition of San Carlos residents, had been significantly white. Beginning in 1970, 125 African-American students from East Palo Alto were bused into San Carlos, a number that increased each year. Often, bus routes departed these neighborhoods at 6 a.m. to arrive in San Carlos before the start of school. Despite training for teachers on how to accommodate new students, the integration contributed to tension among students and sent shock waves throughout the San Carlos community. In 1976 and 1977, this tension escalated into continual fights between students, leading to police presence on campus and frequent intervention:"I have vivid memories of the riots. The school was built like a big wagon wheel, like a half circle with a big area in the middle where people could hang out and do activities. One of the activities in the school was called a 'Slave Auction.' Well, we should have thought ahead of time that this term might not be a very polite way to put it, as far as getting along with new people from East Palo Alto. A fight broke out. And eventually, there were a lot of policemen on campus with guns and dogs, and riot gear, and tear gas. But I never saw anyone get shot. I can recall grabbing some kid in a bear huge and hauling him off to the office. There were no real serious injuries, but it was pretty obvious that what we were doing wasn't working real well." — Bill Hayes, teacher at San Carlos High School from 1965 to 1982, as narrated in Linda Wickert Garvey's
