After the Second World War, the population of Palatine had outgrown the capacity of Palatine High School, and a second facility was needed to handle the additional students. In 1961, Palatine High School South opened at the intersection of Quentin Road and Illinois Street. Originally, PHS South served only freshmen and sophomores, with juniors and seniors attending Palatine High School. After three years, the two schools both became four year high schools, and PHS South was renamed in honor of William Fremd, who served on local school boards for over four decades. Fremd High School had its first graduation in 1968.

Over the next four decades, the school progressively grew, adding to both the curriculum and the building as the area’s population burgeoned and science and technology advanced. Today, in the 21st Century, Fremd High School hosts nearly 3,000 students and has a faculty of over 200 teachers. FHS has received countless awards, honors, and recognition for its excellence in academics, athletics, and the fine arts.

William Fremd High School, in partnership with the community, dedicates itself to challenge and inspire all students toward academic excellence, positive social development and mutual respect. Our goal is for all students to meet their highest level of achievement as determined by appropriate and meaningful evaluation. We commit ourselves to a comprehensive system of support to ensure student growth.
