The school was established in the 19th century, moving into its own building in 1891 with an 1897 addition coming subsequently, and joining the Kansas City school system in 1898 as Westport was annexed to Kansas City.^[1] The high school was across the street from Westport Middle School and it opened in the fall of 1908. It was considered the finest school in Kansas City and among the finest in the county, at a cost of nearly $500,000, and built of stone and vitrified brick.^[2]

Westport High School was the last school to become Achievement First in 2009-2010. The purpose was to prepare students for post-secondary education and high-quality careers.
