North Kansas City Schools has four unique high schools: North Kansas City, Oak Park, Staley and Winnetonka.
North Kansas City High School, also known as "Northtown", was the district's first high school. It was followed by Oak Park High School, which opened in the 1965-1966 school year, and later by Winnetonka High School that opened to students in March of the 1970-1971 school year.
The three high schools handled the growing student population of grades 9-12 until 2008, when the fourth high school -- Staley High School -- was completed. The new high school opened in the 2008-2009 school year as Missouri's 1st “Green” High School and was certified as LEED silver, built by U.S. Green Building Council certification standards.
