Located in Rani Pokhari, Kathmandu, it previously taught only members of the ruling family, but was opened to private citizens in 1902.

Feeling humiliated by not being able to communicate in English during his visit to Europe, Jung Bahadur Rana set up a school at his residence in 1853 with two teachers imported from England to teach children of the ruling families.

In 1876, the school began admitting children of high class government officers too.

Initially, the school as a feeder institution was affiliated with Calcutta University, and students had to travel to Kolkata for their high school entrance examination until an examination centre affiliated with Patna University was opened in Kathmandu in 1929.

In 1933, the government established the School Leaving Certificate Examination Board and students did not have to travel to India for their exams.

The school has also started teaching Robotics and Programming classes from Grade 3 and formed a STEAM CLUB (Initiative of KMC Mayor).
