The institution is classified as a C2 category school, formerly known as an Extra-County school, under the Ministry of Education’s revised institutional classification. It serves learners drawn mainly from Uasin Gishu County and surrounding regions.
In line with ongoing education reforms, the school transitioned to St. Catherine Girls’ Senior School under the Competency-Based Education (CBE) framework.

Admissions into the senior school from January 2026 are determined by learner performance in the Kenya Junior Secondary Education Assessment (KJSEA).
