The building is an unusual example of Second Renaissance Revival. This Renaissance Revival style is best identified by its horizontal divisions defined by belt or string courses and by the use of different treatments in each division, notably changes in the shapes, sizes, and surrounds of windows. Arched openings and projecting cornices with dentils are also characteristic of this style. The Crowley School possesses all these distinctive qualities. However, its unusual and elaborate cupola creates an interesting expression of the style. The Second Renaissance Revival was most common in Colorado between 1900 and 1930. The vernacular examples are generally less ornate and on a smaller scale. The Crowley School, its elaborate cupola notwithstanding, is indicative of that pattern. The school is also the only known example of the style in Crowley County.〔
