South Shore High School is one of the two defunct New York City public high schools in Canarsie, Brooklyn, the other being Canarsie High School. Opened in 1970, it had a capacity of 4000 students in grades nine through twelve. At the peak of enrollment, during the 1972-74 school years, the comprehensive high school had a student population of 6,800, making South Shore the second largest high school in the United States at the time. To accommodate the large capacity of students 13 class periods were provided. The freshmen and sophomores were accommodated in the afternoon–early evening, while juniors and seniors were instructed in the early to late morning. An evening adult education center opened in 1973.
