Champion Standing was the highest award given in the Klingon Bat'leth competition on Forcas III. Winners of Champion Standing were given a trophy in the shape of the Klingon trifoil.
In 2370, Lieutenant Worf won Champion Standing at the tournament. On stardate 47391.2, he made a log entry aboard the shuttlecraft Curie while en route back to the USS Enterprise-D explaining his victory. (TNG: "Parallels")
During his time on Deep Space 9, Worf displayed his trophy on a shelf in the quarters he shared with his wife, Jadzia Dax. (DS9: "Resurrection" et al)
