The drama program has performed four different plays since the birth of the school; Dracula, Into the Woods, Kurt Vonnegut Jr.'s Welcome to the Monkey House, and Bye-Bye Birdie.

[3] In 1879, St. Louis' College, a religious boarding school for girls, was built in a location in the present-day Mission Flats.

Foresight, analysis, and predictions proving incorrect later resulted in the demise of this location, as the city began to expand eastward, towards present-day Valleyview, instead of proliferating west, as was expected.

This made the religious campus, which was located in the far-west, then-undeveloped suburbs of the town, somewhat impractical when it came to transport and access.

[7] In 1950, a new proposal was prepared which put less emphasis on the more lavish features of the building, and focused more on dedicated facilities for proper education, which were designed to last much longer than those built at the previous campus.

This time, the referendum passed, and construction began in 1951 on the new school, located between Eighth and Ninth Avenue on Munro Street.

The dormitory present in the original proposal was ultimately built, and residential students from neighbouring districts without a dedicated secondary school stayed here.

This new sector, consisting entirely of science-oriented classrooms and labs, was built to specification equalling or exceeding university or senior secondary scientific facilities, and boosted KJSS's reputation as a school with academic-oriented intentions.

In 1970, the old auditorium at the school was deemed antiquated and inadequate, and was subsequently replaced in 1978 by the present Sagebrush Theatre, which was built on a joint contract with the City of Kamloops, and now serves as a joint school-public theatre, providing a location for school drama classes and also serving as a base for many public productions.

[12] In recent years, numerous proposals have been pitched to replace the aging SKSS building with brand-new facilities, but none have succeeded.
