The former Waterville High School in Waterville, Maine is eligible was listed in the National Register of Historic Places at the local level of significance for its architecture as a distinctive example of early 20th century Collegiate Gothic style school design and construction with later, sympathetic Art Deco-influenced additions. With multiple architects and builders informing the design of the school and two additions over a period of three decades, the variation and execution of architectural style creates an overall cohesive design that reflects the time and function for which the building was created and altered. It is also for its association with local education practices as the first school built specifically for high school education in Waterville after its incorporation as a city. Striving to maintain a high quality of public education for the community, Waterville High School enrolled students for half a century and evolved to accommodate growing attendance and changes in curriculum, especially during the Depression era. As the curriculum shifted from classical studies to more practical subjects preparing students who would not continue to higher education, new facilities were required to accommodate new subjects. The Manual Arts Training Wing and Gymnasium additions were constructed to meet the needs of the changing curriculum and growth of student enrollment which were directly influenced by the agrarian and industrial bases of the economy in Maine. Constructed between 1909 and 1913, with Works Progress Administration (WPA) funded additions in 1936 and 1938, the property retains integrity of location, design, setting, material, workmanship, feeling and association and has a period of significance from 1909-1940.
