Summary

Corning High is a public high school located in Corning, California, serving grades 9-12 with a total enrollment of 956 students. The school is part of the Corning Union High School District, which is ranked 1340 out of 1543 districts in California and has a 1-star rating from SchoolDigger.

Corning High faces several key challenges, including below-average academic performance, high chronic absenteeism, and a student population with significant socioeconomic disadvantages. The school's academic performance, as measured by standardized test scores, is generally below the state average, with only 41.74% of students proficient or better in English Language Arts/Literacy and 15.61% in Mathematics. Corning High's performance on the California Science Test (CAST) is also below the state average, with only 19.18% of 11th-grade students and 18.95% of all students proficient or better. The school's four-year graduation rate has fluctuated in recent years, ranging from 86.2% to 97.4%, which is generally on par with or slightly below the state average, and its dropout rate has varied from 1.0% to 8.9%, which is higher than the state average.

Interestingly, Corning High's academic performance is generally lower than that of nearby schools, such as Hamilton High and Los Molinos High, which have higher proficiency rates in English Language Arts/Literacy and Mathematics. The school's ranking for female students is generally higher than for male students, indicating potential gender-based achievement gaps. Despite the school's relatively high spending per student, which has increased from $12,907 in 2021-2022 to $17,725 in 2023-2024, its academic performance remains below the state average, suggesting that factors beyond just funding may be contributing to the school's challenges.
