Is it getting better · CAASPP 2019 to 2025
Slipped from the 60th to the 42nd percentile since 2019.
Most rating sites would stop at “37% proficient” and call it done. Colony deserves a closer read. Two-thirds of its students qualify for free or reduced lunch (California: 64%) — and reading the numbers without that context misreads the school.
Colony's low-income kids hit 51.5% 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.
482 tested · 1 of 1 grade published
Colony High scores 50 of 100 on SchoolScope's Scope Score — the 42nd percentile of 1,647 California high schools (CDE CAASPP 2025).
This school hasn't fully recovered from the pandemic: 37% meet the standard today, versus 47% in 2019 — a gap worth asking about on a visit.

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, 67% of this class's predecessors enrolled in college somewhere within a year. More of the class of 2023 enrolled at community colleges (156) than at UC (39).

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 how the school follows up when a student starts missing days — chronic absence often starts outside the classroom, not inside it.
- 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.
Questions
Frequently asked questions
Is Colony High a good high school?
Colony High has a Scope Score of 50 out of 100, placing it in the 42nd percentile of California high schools and ranked #955 statewide. 15.8% of students exceeded the state standard on the 2025 CAASPP assessment, which is 4.1 percentage points below the California average of 19.8%. 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 Colony High's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 37.3% of students at Colony High met or exceeded the state standard in ELA and Math combined, and 15.8% exceeded it. The gap between those numbers matters: 21.6% of students are at the proficiency floor, while 15.8% 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. 964 student-subject combinations were assessed.
How does Colony High rank in California?
Colony High ranks #955 among California high schools by Scope Score, placing it in the 42nd 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 Colony High?
31.4% of students at Colony High are chronically absent (missing 10% or more of school days), compared to the California average of 23.1%. The suspension rate is 4.9%. 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 Colony High compare to other schools in Ontario?
Colony High scores 50/100 (42nd percentile) among California high schools. To compare with nearby schools, SchoolScope shows the same metrics side by side: exceeded rate, proficiency, growth trajectory, and school culture indicators. The school serves 2,109 students. Use the schools in Ontario page or the map view to compare all high schools nearby.
How does Colony High serve low-income and underrepresented students?
At Colony High in Ontario, 51.5% of low-income students met or exceeded the ELA standard in 2025, compared to 63.9% district-wide and 38.2% statewide. Colony High trails its district average for low-income students by 12.4 percentage points in ELA. Other subgroups: Low-Income students (18.8% Math proficient); Hispanic students (58.1% ELA proficient). The largest proficiency gap is 41.9 percentage points for disabilities students. Data source: California Department of Education, CAASPP 2024-25. 357 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.
What AP courses are offered at Colony High?
Colony High's teachers are authorized to teach 3 of the 40 AP subjects the College Board offers, per the 2025 - 2026 AP Course Audit: 3-D Art and Design, Psychology, U.S. Government and Politics. Authorization means the school may teach a course, not that a section is running this year, and it's separate from AP exam pass rates. Data source: College Board AP Course Audit, analyzed by SchoolScope.
How many students from Colony High go to UC?
In fall 2025, 36 Colony High graduates enrolled at University of California campuses, universitywide. That figure can't be split into a per-campus sum — students apply to several UC campuses at once, so campus-level counts don't add up to the universitywide total. UC is one destination among many: this says nothing about graduates who chose a CSU, a private college, a community college, or work, and it is a count, not a rate or a ranking. Data source: University of California Office of the President (UC Information Center), fall 2025 admissions cycle.
