The chevron was by far the most common heraldic division the Intercollegiate Bureau of Academic Costume (IBAC) employed to divide the two or three colors in an institution’s hood, but beginning in 1895 the “double chevron” was also used quite frequently. The typical width of a normal chevron was between three and four inches, but the double chevron pattern used two chevrons of about 1½ inches in width placed approximately two inches apart so that the color of the hood lining showed between them.

Iowa State Teachers College was cited in IBAC lists from 1927, 1948, and 1972 as having a hood lined gold with two purple chevrons. The college must have sent the Bureau a sample of its old gold color that was closer to a bright gold, which would explain the IBAC’s slightly inaccurate assignment of the college’s hood lining colors. Here the correct colors of old gold and purple have been used.
