Summary

William & Marian Ghidotti High is a small, top-ranked public high school serving 155 students in grades 9-12 within the Nevada Joint Union High school district in Grass Valley, California.

The school's academic performance is exceptional, consistently ranking among the very best in the state; for the 2024-2025 year, it ranked 3rd out of over 2,100 California high schools. Proficiency rates are remarkably high, with 100% of students proficient in English Language Arts, nearly 89% in Mathematics, and over 91% in Science, far exceeding both district and state averages. This excellence is reflected in strong student outcomes, including a 97.3% graduation rate and very low chronic absenteeism and dropout rates.

Ghidotti's success is particularly striking when compared to other local schools like Bear River High and Nevada Union High in the same district, where proficiency rates are significantly lower. Interestingly, the school achieves these results with a higher student-teacher ratio and lower per-student spending than neighboring schools, suggesting a highly effective and efficient educational model. While it serves a smaller and somewhat different student population than some nearby schools, including the continuation school Silver Springs High located less than two miles away, Ghidotti has maintained its elite status for over a decade.

Ghidotti is not just a school. It's a community. Our low student count and dedicated (and awesome!) staff let us feel at home at school among our classmates. You know the names of your peers in class and are not uncomfortable with consulting your teachers when you encounter a challenge. Ghidotti is a fantastic place to learn and grow! Close Quote

This is a fabulous early college high school. The staff is engaged and caring - we are fortunate that our children have the opportunity to attend such a great school while living in a small town. Close Quote
