Northside College Preparatory High School

Northside College Preparatory High School (commonly referred to as Northside College Prep, Northside Prep, or simply Northside) is a public 4-year selective enrollment magnet high school located in the North Park neighborhood on the northside of Chicago, Illinois, USA. Founded in 1999, it was the first new Chicago Public High School to be built in 20 years. It is a selective enrollment school, teaching at the Honors and AP levels only (excluding the P.E. department). Northside quickly earned a reputation for academic excellence, and has been consistently ranked as the #1 public high school in Illinois by US News and many other publications. Since its inception, it has scored very high in the state on the Prairie State Achievement Exam scores, administered to juniors.

In 2003, the school's Academic Decathlon ("acadec") team defeated Chicago's Whitney Young High School to take first place in the state; it was the first time in 18 years Whitney Young had not gone home with this title. It went on to win the United States Academic Decathlon (USAD) Division III National Championship.

The school's establishment, part of Chicago Mayor Richard M. Daley's ongoing plan to reinvent the city's public school system, generated controversy in the city and in the education community. The facilities were built with a $52.5 million budget that critics said could have better served other schools in the city. The student body comprises approximately 1,100 students. Given its extremely competitive academic environment, Northside successfully lobbied the Chicago Board of Education to eliminate class rankings. This effort was led by Dr. James Lalley.
