Previous to the 1978-79 school year, U-46 high school students that lived in Streamwood attended either Elgin High School or Larkin High School, which were open campuses.   Streamwood High School was under construction from fall of 1976 to fall of 1978.  Streamwood High School opened in August of 1978 with only sophomore and junior classes.  Seniors were allowed to finish their high school career at Elgin or Larkin High School.  Campuses were closed once Streamwood High School opened.  In the fall of 1979 Streamwood High School became a three-year campus.

Prior to 1982, all freshmen were housed at district junior high schools, Tefft and Canton for Streamwood residents.  If the fall of 1982, all district high schools became four-year campuses. 

Streamwood High School has seen three additions to the building since it opened.  The first addition added the wing that houses the south gym and the classrooms on the second and third floors above the south gym.  The second addition added rooms on the first floor east side of the building.  The third addition added our AVID center.

Millennium Field opened in the fall of 1997.  Until that point, the three high schools in the district - Elgin, Larkin and Streamwood - all played their home games on Memorial Field at Elgin High School.  Millennium Field was a welcome addition to the Streamwood High School Campus and became the home field for Bartlett High School and South Elgin also, until their fields were built.

The 2020-2021 school year will be Streamwood High’s forty-third in operation.  The current administration and faculty will continue to strive for excellence in both academics and extra curricular activities.
