The lamp at the apex is a symbol of knowledge and learning.

It was redesignated for the Army Information School and amended to change the wording on the scroll on 25 Jan 1955. On 1 Jul 1964 the device was reassigned to the Defense Information School and amended to change the wording in the scroll.
