After many years of time spent toiling classrooms and study halls, many students welcome graduation. Graduating high school or college is a major milestone. It is associated with many symbols that have endured for some time. As graduates prepare to receive their diplomas or degrees, they might be curious to know what's behind some notable symbols of graduation ceremonies.

· Gown: The gown is a customary garment worn on graduation day. The Georgia Institute of Technology says gowns historically were heavy robes worn by medieval scholars for warmth in the largely unheated universities. Today, graduates don gowns not for warmth (as most graduation ceremonies take place in the spring and summer), but to symbolize the level of degree being conferred.
