Decker Elementary scores 31 of 100 on SchoolScope's Scope Score — the 20th percentile of 5,744 California elementary schools (CDE CAASPP 2025).

Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →

🌱 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 “30% proficient” and call it done. Decker deserves a closer read. The school sits in Pomona, where three in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Test scores are one lens, and at this school they're a rough one right now. The sections below show the fuller picture — including the parts that are working.

Worth a school visit

Ask what changed in the last two years, and what the school is asking families for. Growth shows up in these numbers a year or two after it shows up in classrooms.

  • 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 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.

These measure different things: this figure is spending attributed to this campus, while district-wide figures also include central administration, districtwide programs, and the state's pension contributions made on the district's behalf — costs that never get assigned to a single school. The district number runs higher at nearly every school, not just this one.

Frequently asked questions

Is Decker Elementary a good elementary school?

Decker Elementary has a Scope Score of 31 out of 100, placing it in the 20th percentile of California elementary schools and ranked #4,594 statewide. 11.4% of students exceeded the state standard on the 2025 CAASPP assessment, which is 9.9 percentage points below 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 Decker Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 29.8% of students at Decker Elementary met or exceeded the state standard in ELA and Math combined, and 11.4% exceeded it. The gap between those numbers matters: 18.4% of students are at the proficiency floor, while 11.4% 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. 331 student-subject combinations were assessed.

How does Decker Elementary rank in California?

Decker Elementary ranks #4,594 among California elementary schools by Scope Score, placing it in the 20th 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 Decker Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Decker Elementary decreases by 12.4 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 Decker Elementary?

23.8% of students at Decker Elementary are chronically absent (missing 10% or more of school days), compared to the California average of 17.9%. The suspension rate is 0.1%, 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 Decker Elementary compare to other schools in Pomona?

Decker Elementary scores 31/100 (20th percentile) among California elementary 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 437 students.

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.
