|"Mount Washington School, located at 570 S. Evanston Avenue, Independence, Jackson County, Missouri, is locally significant under National Register Criterion A for the area of EDUCATION and Criterion C for the area of ARCHITECTURE. Built over the course of twenty years, the property reflects the evolution of public school architecture and educational philosophy. The sections of the Mount Washington School illustrate two different property types identified in the Multiple Property Documentation Form (MPDF) ""Historic Resources of the Kansas City Missouri School District Pre-1970."" The earliest section of the building was constructed in 1903 for the Mount Washington School District. The growing local student population required additional space, resulting in two additional building campaigns in 1910 and 1924, each of which roughly doubled the size of the existing school. Andrew B. Anderson designed the 1903 block and , presumably, the 1910 block. These sections illustrate the Ward School/Graded School property type. The Kansas City Missouri School District (District) annexed the Mount Washington School District in 1911 and operated the school until 2007. Charles A. Smith, the Kansas City, Missouri Board of Education Architect, designed the 1924 addition, incorporating many of the Progressive Era features he promoted for schools in the District, such as a branch of the public library, a large ""fresh air"" classroom, and an integrated auditorium and gymnasium. The historic configuration and many finishes remain intact on both the exterior and interior of Mount Washington School, reflecting the evolution of educational philosophies discussed in the context ""Public Education in Kansas City, Missouri (1867-1970),"" specifically the ""Early Years (1867-1899) "" and ""Progressive Era (1900-1932)"" sub-contexts. The nominated resource also reflects the architectural evolution of school buildings, as described in the context ""Public School Buildings in Kansas City, Missouri,"" specifically the ""Late Nineteenth Century Schools (1867-1899)"" and ""Early Twentieth Century Schools (1900-1940)"" subcontexts. The Mount Washington School continues to communicate its historic educational function and the eras in which it was constructed. The period of significance is 1903 through 1963, beginning with the date of construction and ending with the fifty-year closing date for periods of significance where activities begun historically continue to have importance but no more specific date can be defined."
