Endeavour Middle scores 17 of 100 on SchoolScope's Scope Score — the 6th percentile of 1,714 California middle schools (CDE CAASPP 2025).
Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “12% proficient” and call it done. Endeavour deserves a closer read. The school sits in Lancaster, where four in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: 28.0% of English learners reached the top ELPAC level, versus 17.7% statewide.

Frequently asked questions
Is Endeavour Middle a good middle school?
Endeavour Middle has a Scope Score of 17 out of 100, placing it in the 6th percentile of California middle schools and ranked #1,612 statewide. 1.8% of students exceeded the state standard on the 2025 CAASPP assessment, which is 15.5 percentage points below the California average of 17.3%. The Scope Score weights six dimensions for middle schools: exceeded standard (43%), met or exceeded (22%), grade 3-to-5 growth (15%), chronic absenteeism (10%), ELPAC English Learner proficiency (5%), and suspension rate (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.
What are Endeavour Middle's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 11.6% of students at Endeavour Middle met or exceeded the state standard in ELA and Math combined, and 1.8% exceeded it. The gap between those numbers matters: 9.8% of students are at the proficiency floor, while 1.8% 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. 1,494 student-subject combinations were assessed.
How does Endeavour Middle rank in California?
Endeavour Middle ranks #1,612 among California middle schools by Scope Score, placing it in the 6th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), grade-level growth (Grade 6 to grade 8 growth), 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.
Is Endeavour Middle getting better or worse?
Based on 2025 CAASPP data, proficiency at Endeavour Middle decreases by 0.6 percentage points from Grade 6 to grade 8 growth. This downward pattern doesn't necessarily mean the school is failing — it can reflect cohort differences, demographic shifts, or curriculum changes. A campus visit and conversation with teachers can reveal what the numbers can't. Growth trajectory is weighted at 15% in the middle Scope Score because it measures what the school does, not just who walks in the door.
What is the attendance and school culture like at Endeavour Middle?
28.0% of students at Endeavour Middle are chronically absent (missing 10% or more of school days), compared to the California average of 19.1%. The suspension rate is 10.6%. 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 Endeavour Middle compare to other schools in Lancaster?
