Plainsburg Union Elementary scores 30 of 100 on SchoolScope's Scope Score — the 16th 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 “39% proficient” and call it done. Plainsburg Union deserves a closer read. The school sits in Merced, where two in five 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 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.

What are Plainsburg Union Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 39.0% of students at Plainsburg Union Elementary met or exceeded the state standard in ELA and Math combined, and 11.0% exceeded it. The gap between those numbers matters: 27.9% of students are at the proficiency floor, while 11.0% pushed past it. Most rating sites report only the combined "proficient" number.

How does Plainsburg Union Elementary rank in California?

Plainsburg Union Elementary ranks #4,797 among California elementary schools by Scope Score, placing it in the 16th 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 Plainsburg Union Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Plainsburg Union Elementary decreases by 2.5 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 Plainsburg Union Elementary?

The suspension rate is 0.5%, 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.
