What this means for your family

Ask what happens for a kid who shows up behind — a high ceiling for the top can sit right next to thin support at the bottom, and the score alone won't show you which.

What gets spent · FY 2024–25

It spends $14,283 per student, about the same as the California average.

Context — never part of the Scope Score

These measure different things: this figure is spending attributed to this campus, while district-wide figures also include central administration, districtwide programs, and the state's pension contributions made on the district's behalf — costs that never get assigned to a single school. The district number runs higher at nearly every school, not just this one.

$115 per student arrives as federal Title funding — a measure of concentrated need, not school quality.

The district's current expense of education per student, from CDE's annual SACS filing — the freshest district spending figure the state publishes.

Worth knowing

At 155 students, this school is much smaller than the typical California high school (≈1450).

On the state's science test (CAST), 92% met or exceeded the standard — science is tested in grades 5 and 8 and once in high school, and it never enters the Scope Score.

What should I do next?

Worth a school visit

Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.

  • Ask what share of students complete the full college-prep course sequence, and who gets steered into it.
  • Ask whether the tour can step into a working classroom — watch how the teacher handles a student who's stuck.
  • Ask to tour while school's in session, and notice how hallways and transitions feel — culture shows up between classes, not just in them.
  • Ask how the school communicates with families when a child starts to struggle.
  • Ask what a typical day looks like for a new student in the first few weeks.
Questions

Frequently asked questions

Is William & Marian Ghidotti High a good high school?

The Scope Score weights 7 dimensions for high schools: graduation rate (25%), exceeded standard (22%), college/career readiness (20%), met or exceeded (proficient) (18%), chronic absenteeism (5%), suspension rate (5%), and ELPAC English Learner proficiency (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.
What are William & Marian Ghidotti High's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 94.5% of students at William & Marian Ghidotti High met or exceeded the state standard in ELA and Math combined, and 79.2% exceeded it. The gap between those numbers matters: 15.3% of students are at the proficiency floor, while 79.2% went beyond it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it shows how many students go beyond the standard rather than only meeting it. 72 student-subject combinations were assessed.
How does William & Marian Ghidotti High rank in California?
William & Marian Ghidotti High ranks #100 among California high schools by Scope Score, placing it in the 94th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), chronic absenteeism, and suspension rate. Unlike single-number ratings, the Scope Score shows what drives the ranking so parents can decide what matters most to their family. See full methodology.
What is the attendance and school culture like at William & Marian Ghidotti High?
17.4% of students at William & Marian Ghidotti High are chronically absent (missing 10% or more of school days), which is better than the California average of 23.1%. The suspension rate is 1.1%, indicating a low-discipline-incident environment. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
How does William & Marian Ghidotti High compare to other schools in Grass Valley?

Use the schools in Grass Valley page or the map view to compare all high schools nearby.
How does William & Marian Ghidotti High serve low-income and underrepresented students?
At William & Marian Ghidotti High in Grass Valley, 100.0% of white students met or exceeded the ELA standard in 2025, compared to 66.5% district-wide and 61.8% statewide.

Data source: California Department of Education, CAASPP 2024-25. 29 students tested. SchoolScope shows disaggregated test scores by demographic subgroup so you can see how a school performs for your child's specific group — not just the school-wide average. Subgroup data is context, not part of the Scope Score: we don't penalize schools for who they serve. See our equity approach.

A closer look at the evidence

William & Marian Ghidotti High: reading the evidence

William & Marian Ghidotti posts 79.2% exceeding the standard — versus 19.8% statewide — with climate numbers better than most. That doesn't make it perfect. It makes it worth a visit to find what numbers can't measure.

Subject proficiency describes tested students, while graduation describes a graduating cohort. These figures are not successive stages followed by the same students.

Ask what happens for a kid who shows up behind — a high ceiling for the top can sit right next to thin support at the bottom, and the score alone won't show you which.
