SchoolDigger Rank ?

of 2,135 California High Schools

Better than 23% of California high schools

Summary

Grizzly ChalleNGe Charter is a small high school in San Luis Obispo, serving 241 students in grades 10–12 in San Luis Obispo County. Its reported outcomes point to comparatively strong graduation and attendance, but its academic proficiency results are a serious concern: in 2025–2026, only 13% of students were proficient in English language arts (ELA) and 2% in math.

Science is the school’s strongest subject compared with nearby schools, its district and the state. About 30% were proficient, above the 29% average among nine nearby schools with reported scores and the San Luis Obispo County Office of Education result of 20%, though below the state’s 36%. ELA and math were above district results—13% versus 9% in ELA and 2% versus 1% in math—but far below state results of 49% and 38%. Among those nearby schools, Grizzly’s ELA result was second-lowest, and its math result was below five of the nine; its science result was fifth-highest. Graduation was 89%, compared with 88% statewide, while chronic absenteeism was 2%, versus 18% statewide.

Results have changed unevenly: science rose 22 percentage points from 2022–2023 to 2025–2026, including a 25-point jump in the latest year, while ELA fell 13 points and math fell 2 points over that span. SchoolDigger placed the school at the 23rd statewide percentile with 1 star in 2025–2026, up from the 11th percentile the year before but still in the lower quarter. Its 2024–2025 student–teacher ratio was 16.3. In that same year, 85% of students were free/reduced lunch eligible; California provides free school meals statewide, so this eligibility figure is context, not a measure of meal access. SchoolDigger’s statewide measure for how well the school serves Special Education Students was at the 2nd percentile in 2025–2026, compared with the school’s overall 23rd percentile. For English Language Learner Students, its latest reported measure was higher: the 38th percentile in 2023–2024, versus the school’s overall 13th percentile that year.
