At its creation in 1959, Sunset High School was part of the Hayward Union High School District, and continued to be until 1963, when that district was dissolved and all of its high schools became part of smaller
unified school districts. At that time, Sunset High School became part of the Hayward Unified School District. On September 25, 1959, the newly chartered State College for Alameda County – now
California State University, East Bay – welcomed its first 293 students to classes in temporary quarters at Sunset High School. The high school was able to share space with the college because, during the 1959–1960 school year, the high school consisted of only the 9th and 10th grades. September 1961 was the first time Sunset had all four high school classes. In the summer of 1966, runners from the track team got together and ran a continuous relay around the clock with the goal of beating Tennyson High School's World Record of a little over 4,000 miles completed in the summer of 1965. After 52 days, Sunset High School did set a World Record of 10,035 1/2 miles of non stop running. Each of the 24 runners ran one hour each. In 1970, social studies students at Sunset High School researched and wrote the book
A History of Hayward. The school closed in 1990 due to declining enrollment. ==Notable alumni and teachers==
