Staley High School is a public high school in Kansas City, Missouri. It is one of the four high schools in the North Kansas City School District along with North Kansas City High School, Oak Park High School, and Winnetonka High School. The school was named after the nearby Staley Farms and the road of the same name. The school opened in the 2008–09 school year with an enrollment of nearly 1,000 students from Oak Park High School. It is the first Green school in Missouri; however, other schools are in the process of being built and/or planned. The school's mascot is the Falcons, and the school's colors are green, black, and silver. Staley's original principal, Clark Mershon, retired in June 2017, and was replaced by the current principal Dr. Larry Smith.
A new District Activities Complex (DAC) for district activities such as a football & track stadium, baseball and softball fields, a soccer field, a cross-country course, and tennis courts are behind the Staley campus. Staley High School has a student capacity of 1,500, but will increase to 2,000 following a future Phase II expansion.
In 2011, the Falcons won the Class Five Missouri State Football Championship by defeating the Kirkwood Pioneers 35–21 at the Edward Jones Dome in St. Louis, Missouri. They also won the state title in 2017, in Columbia, Missouri. They beat Pattonville 36–35 on a last second two point conversion. In 2012 and 2014, The Emeralds Dance Team also won the Class 4A Missouri State Dance Team Championship. The Staley Cross Country team has won conference titles on both the boys and girls sides and sent athletes to state. In 2015, the cross country team sent both boys and girls teams to state. The Wrestling Team won the State Champion title in 2017 against Park Hill High School, the then Number one ranked team in the state. The Staley 2013–2014 Chamber Choir was selected as an MMEA State Choir, and traveled to Ireland for the World Choral Fest in 2013. State Championships and State rankings have been achieved by the choir, band, and orchestra, as well as regional and national awards for the STTV Broadcast program, the magazine, and school yearbook.
