Mossdale Elementary scores 34 of 100 on SchoolScope's Scope Score — the 27th 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 “35% proficient” and call it done. Mossdale deserves a closer read. The school sits in Lathrop, where more than half of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

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 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.

Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.

What are Mossdale Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 35.3% of students at Mossdale Elementary met or exceeded the state standard in ELA and Math combined, and 12.3% exceeded it. The gap between those numbers matters: 23.0% of students are at the proficiency floor, while 12.3% 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. 776 student-subject combinations were assessed.

How does Mossdale Elementary rank in California?

Mossdale Elementary ranks #4,215 among California elementary schools by Scope Score, placing it in the 27th 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 Mossdale Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Mossdale Elementary decreases by 2.1 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 Mossdale Elementary?

16.2% of students at Mossdale Elementary are chronically absent (missing 10% or more of school days), which is better than the California average of 17.9%. The suspension rate is 2.1%. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
