Understanding the 2/10 Rating
Corning Union High School District has earned an overall SchoolDistrictFinder rating of 2/10, placing it in the low-rated tier. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in California’s CAASPP Smarter Balanced assessments (2023–24 school year). We average each district’s reading and math proficiency, then rank it against other districts in the same state to produce a 1–10 score. Because California is compared only against itself, the rating reflects how this district performs relative to its in-state peers.
Corning Union High School District holds a low overall rating, with reading and math proficiency among the lowest in California on state assessments. Test results reflect many factors beyond the classroom, including community and economic conditions; a low score is a signal to research carefully, not a verdict on any individual school or teacher. Families in this area should research all available alternatives: inter-district transfers, charter schools, and magnet programs. Contact the district directly to understand exactly what programs are available at your assigned school.
