Sierra High: Most kids here clear the bar, year after year. The question is what happens after that.

Sierra posts 52% meeting the standard, and 23.5% going well past it. Most kids here keep up. Fewer get pushed further. Ask the school what it does for a child who already finds the work easy.

ranked #636 statewide · #1 of 7 in Manteca Unified

Sierra High scores 57 of 100 on SchoolScope's Scope Score — the 71st percentile of 2,160 California high schools (CDE CAASPP 2025).

CDE CAASPP 2025

Most rating sites would stop at “52% proficient” and call it done. Sierra deserves a closer read. The school sits in Manteca, where more than half of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Sierra's low-income kids hit 64.9% 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.

Worth a school visit

Ask how the school challenges kids who clear the standard early. The gap between meeting and exceeding is where pacing shows.

  • Ask whether extra support — tutoring, counseling, small groups — reaches kids across income lines, not just the students already ahead.
  • 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.

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, 72% of this class's predecessors enrolled in college somewhere within a year. More of the class of 2023 enrolled at community colleges (186) than at UC (22).

Worth Knowing

On the state's science test (CAST), 44% 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.

Frequently asked questions

Is Sierra High a good high school?

Sierra High has a Scope Score of 57 out of 100, placing it in the 71st percentile of California high schools and ranked #636 statewide. 23.5% of students exceeded the state standard on the 2025 CAASPP assessment, which is 7.7 percentage points above the California average of 15.8%. 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 Sierra High's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 51.7% of students at Sierra High met or exceeded the state standard in ELA and Math combined, and 23.5% exceeded it. The gap between those numbers matters: 28.2% of students are at the proficiency floor, while 23.5% pushed past it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it reveals whether a school's curriculum challenges students beyond minimum proficiency or paces toward it. 837 student-subject combinations were assessed.

How does Sierra High rank in California?

Sierra High ranks #636 among California high schools by Scope Score, placing it in the 71st 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 Sierra High?

13.0% of students at Sierra High are chronically absent (missing 10% or more of school days), which is better than the California average of 30.2%. The suspension rate is 2.4%. 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 Sierra High compare to other schools in Manteca?

Sierra High scores 57/100 (71st 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 1,670 students. Use the schools in Manteca page or the map view to compare all high schools nearby.

How does Sierra High serve low-income and underrepresented students?

At Sierra High in Manteca, 64.9% of low-income students met or exceeded the ELA standard in 2025, compared to 32.7% district-wide and 38.2% statewide. Sierra High outperforms its district average for low-income students by 32.2 percentage points in ELA. Other subgroups: Low-Income students (33.3% Math proficient); Hispanic students (59.1% ELA proficient). The largest proficiency gap is 55.2 percentage points for disabilities students. Data source: California Department of Education, CAASPP 2024-25. 242 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 Sierra High?

Sierra High's teachers are authorized to teach 2 of the 40 AP subjects the College Board offers, per the 2025 - 2026 AP Course Audit: Physics 1, Precalculus. 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 Sierra High go to UC?

In fall 2025, 17 Sierra 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.
