Summary

Rancho Cucamonga High is a 3,221-student high school serving grades 9–12 in Rancho Cucamonga, in the Chaffey Joint Union High district.

The school scores above state and district levels in all three subjects. Its proficiency rates were 70% in English language arts, 46% in math and 47% in science, compared with state rates of 49%, 38% and 36%.
