Troy High: High scores, healthy climate, strong attendance. We looked for a catch — we didn't find one.
Troy posts 64.8% 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.
Troy High scores 88 of 100 on SchoolScope's Scope Score — the 98th percentile of 1,647 California high schools (CDE CAASPP 2025).
Measures graduation, test performance, college readiness, attendance, and climate — not arts, community, or your kid. How we score →
High Ceiling — 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.
Most rating sites would stop at “83% proficient” and call it done. Troy deserves a closer read. One in three of its students qualify for free or reduced lunch (California: 64%) — and reading the numbers without that context misreads the school.
Troy's low-income kids hit 77.7% proficiency in ELA — a number the same group reaches at 38.2% statewide. If you're trying to read past zip-code-driven test scores, that's the signal worth weighing.

Of 100 students here: 83 are proficient by 11th grade → 95 graduate → 88 pass an AP exam. The gaps between those bars are the questions to ask.
Troy's most underrated number
77.7% of low-income students met the ELA standard — versus 38.2% for the same group statewide. That's the strongest kind of signal a school can post: it holds across income lines.
The 7 things our score weighs
Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.
- Ask whether extra support — tutoring, counseling, small groups — reaches kids across income lines, not just the students already ahead.
- 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.

In fall 2025, 140 of Troy's 627 graduates enrolled in the University of California system — Riverside the most common landing, with 38 enrollees.
campuses never sum to the universitywide figure — students apply to several
Peak: 177 enrolled, 2016
UC publishes this trend back to 1994 — no other destination has a comparable multi-year record
UC is one road of many — the full destination mix for the class of 2023 is below. And who applied isn't who the school taught: the ratio between the two reflects the self-selected pool of students who chose to apply, not what happened in the classroom. By the state's 2023 count, 89% of this class's predecessors enrolled in college somewhere within a year. More of the class of 2023 enrolled at community colleges (180) than at UC (122).

The people teaching here
Pay is set by the district, not the school.
Troy's teachers are authorized to teach 26 of the 40 AP subjects the College Board offers — well above the 14-subject median among California schools that offer AP at all — including Calculus BC, Calculus AB, and Physics C: Mechanics.

What gets spent here
$87 per student arrives as federal Title funding — a measure of concentrated need, not school quality.
