Summary

Sisson serves 274 students in grades 4–8 in Mount Shasta, California. In 2025–2026, its all-grade proficiency was 40% in English language arts (ELA), 29% in math, and 31% in science—about 9, 9, and 5 percentage points below state results, respectively. Grade-level results show the most pressing concern: math proficiency was just 14% in sixth grade and 16% in seventh grade, 23 and 21 points below the state.

Science is Sisson’s strongest subject relative to California, while math is weakest, though its state gap is nearly the same as ELA’s. Compared with the Mt. Shasta Union Elementary district, Sisson was essentially tied in all-grade ELA (about 40% for both), 2 points lower in math (29% versus 31%), and tied in science (31%). The supplied district results match Sisson’s in every listed grade and subject. Within Sisson, results vary considerably: fourth- and eighth-grade math were 5 and 12 points above the state, while fifth- and seventh-grade ELA were 17 and 20 points below. There are no other schools within 20 miles, so nearby-school comparisons are unavailable.

Results have shifted unevenly over time: from 2022–2023 to 2025–2026, ELA fell 3 points and math fell 6, while science rose 3. SchoolDigger’s statewide standing also declined, from the 71st percentile and 4 stars in 2021–2022 to the 43rd percentile and 2 stars in 2025–2026; its latest rank is 1,534th of 2,703 California schools. SchoolDigger’s statewide measure of how well Sisson serves White students is at the 22nd percentile, compared with 43rd overall; its measure for Low Socio Economic Status Students is at the 25th percentile, down from 78th in 2023–2024. The student-teacher ratio was 22.5 in 2024–2025, up from 19.6 in 2022–2023. Sisson reported 34% free/reduced lunch eligible in 2024–2025; this is context, not an explanation for the results.
