It had been open for centuries until it was closed in 1872, when the First Accords were signed, as a show of good faith that Downworlders and Shadowhunters were no longer at war.
In 2012, after Inquisitor Robert Lightwood was killed, Centurion Diego Rosales hid the faerie Kieran within the Scholomance to protect him from the Cohort. Kieran was eventually found and tormented by the Cohort until Diego, Rayan Maduabuchi and Divya Joshi rescued him and sent him away.
After the Cohort banished themselves to Idris, several staff members joined them, while Jia Penhallow took over the school, with Ragnor Fell among the teachers. Tiberius Blackthorn started attending the Scholomance.
The Scholomance trains the most elite Shadowhunters, particularly those that graduated with the highest honors from the Shadowhunter Academy. Before admittance, one had to pass a series of harsh tests. What was learned at the school was not to be shared with others. Students who graduate from the school become Centurions.
The Scholomance is a castle, with towers and corridors carved into the side of a mountain in the Carpathians. It is said to be much harder and lonelier than the Academy, and some of the students have wound up failing out with nervous breakdowns.

- Tiberius Blackthorn wanted desperately to one day go to the Scholomance, before he met the Cohort.
