The team graduated from Beacon Academy before the start of the series. Qrow reveals that they were rather well known during their time at Beacon, meaning they likely had similar reputations and accomplishments to the team which their children became part of, Team RWBY.
After Team STRQ first formed, Taiyang and at least one other member, likely Summer by process of elimination, played a prank on Qrow. He had never seen a school uniform before, so they told him that the girl's uniform skirt was actually a kilt. When Qrow appeared in class, then-Teacher's Assistant Peter Port had to leave and privately laugh. Later, Qrow had to publicly work on his landing strategy while wearing the skirt, a memory Taiyang would find hilarious for years. Taiyang also claims that this prank did Qrow a favor as it helped him catch the positive attention of girls in the school.
