Signal Academy is a primary combat school located on the island of Patch, just off the coast of Vale. Ruby Rose is a former student of Signal Academy, where she forged and learned to wield Crescent Rose. However, she was moved up two years due to an invitation to join Beacon Academy from the headmaster, Professor Ozpin.
Ruby and Yang Xiao Long's father, Taiyang Xiao Long, is a teacher, and their uncle, Qrow Branwen, was a teacher at Signal Academy. At Signal, all students are required to craft their own weapons. Ruby is also the only known student in the series to attend Signal thus far; however combined with the fact that both her father and uncle taught there, it is likely that Yang also attended Signal.
In "Ruby Rose", when asked where she learned to fight the way she does, Ruby answers that she learned at Signal, surprising Ozpin with the skill she displayed with such a dangerous weapon. She then admits that her uncle, Qrow, a teacher at Signal, had actually taught her how to fight using her scythe. Later, when flying to Beacon Academy, Ruby says that she can see Signal from the airship.
The night before the Beacon Academy Initiation, Ruby writes a letter to her friends back at Signal to tell them what Beacon is like. Yang Xiao Long teases her a bit, but Ruby objects by noting she did not get to bring her friends when she left Signal and how it was odd to not have anyone else with her that she knows at Beacon.
- As seen with Beacon, Signal and Pharos, combat schools in Vale seem to be named after buildings or devices made to navigate, communicate or attract attention.
