Willow Elementary · Glendora

Willow Elementary: English learners reach fluency faster than the state rate. But this year's 5th graders test below its 3rd graders.

Willow has real strengths and one number that complicates them. Most rating sites show you one or the other. Both belong on the same page.

Willow Elementary scores 50 of 100 on SchoolScope's Scope Score — the 67th percentile of 5,744 California elementary schools (CDE CAASPP 2025).

🌱 Building Momentum — This label means the data doesn't clearly sort the school one way or the other — ask what the school is proud of, and what it's working on.

Most rating sites would stop at “59% proficient” and call it done. Willow deserves a closer read. The school sits in Glendora, where two-thirds of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Willow's low-income kids hit 51.9% 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 the principal what changes between grade 3 and grade 5. Ask who teaches the older grades, and what the school does when a child starts falling behind.

  • Ask how the school follows up when a student starts missing days — chronic absence often starts outside the classroom, not inside it.
  • Ask what changes between grade 3 and grade 5 here, and who teaches the older kids.
  • 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.

On the state's science test (CAST), 35% met or exceeded the standard — science is tested in grades 5 and 8 but never enters the Scope Score.

Frequently asked questions

Is Willow Elementary a good elementary school?

Willow Elementary has a Scope Score of 50 out of 100, placing it in the 67th percentile of California elementary schools and ranked #1,910 statewide. 34.3% of students exceeded the state standard on the 2025 CAASPP assessment, which is 13.0 percentage points above the California average of 21.3%. The Scope Score weights 6 dimensions for elementary schools: exceeded standard (38%), grade 3-to-5 growth (27%), met or exceeded (proficient) (20%), 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 Willow Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 58.9% of students at Willow Elementary met or exceeded the state standard in ELA and Math combined, and 34.3% exceeded it. The gap between those numbers matters: 24.6% of students are at the proficiency floor, while 34.3% 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. 280 student-subject combinations were assessed.

How does Willow Elementary rank in California?

Willow Elementary ranks #1,910 among California elementary schools by Scope Score, placing it in the 67th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), grade-level growth (Grade 3 to grade 5 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 Willow Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Willow Elementary decreases by 49.8 percentage points from Grade 3 to grade 5 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 elementary 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 Willow Elementary?

24.6% of students at Willow Elementary are chronically absent (missing 10% or more of school days), compared to the California average of 17.9%. The suspension rate is 1.4%, 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 Willow Elementary compare to other schools in Glendora?
