The Intercollegiate Bureau of Academic Costume (IBAC) assigned an unusual hood lining that featured a bi-chevron to San Francisco Theological Seminary in the 1930s or early 1940s. A 1948 IBAC list described the hood as cardinal with a blue and gold chevron. This indicated a standard three- or four-inch wide chevron that had been divided into two parts: a blue chevron 1½ to two inches in width and a gold chevron 1½ to two inches in width. The cardinal lining did not show between them.

The Bureau had occasionally used tri-chevrons since 1895, but this was apparently the first time a bi-chevron was assigned.

The IBAC may have redesigned the hood to something more traditional in the 1950s, because a list of hood lining patterns compiled by Kevin Sheard in 1962 cited the seminary as having a hood lined scarlet above a golden yellow chevron, with royal blue below. A 1972 Intercollegiate Bureau list uses a slightly different description: “scarlet over blue” separated by a gold chevron.

To avoid confusion with a similarly-designed hood the Bureau assigned to Blue Mountain College, here the original (and unusual) IBAC design has been retained.
