Carlton Elementary · San Jose

Carlton Elementary: More than half of kids exceed the standard. But this year's 5th graders test below its 3rd graders.

Carlton is one of the strongest elementary schools in San Jose by raw achievement. The catch worth understanding: the cohort doesn't gain ground year-over-year.

⭐ High Ceiling · Strong
ranked #389 statewide · #3 of 6 in Union Elementary

Carlton Elementary scores 72 of 100 on SchoolScope's Scope Score — the 93rd 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 →

⭐ High Ceiling — Ask what happens for a kid who shows up behind — a high ceiling for the top can sit right next to thin support at the bottom, and the score alone won't show you which.

Most rating sites would stop at “77% proficient” and call it done. Carlton deserves a closer read. It sits at the 93rd percentile of 5,744 California elementary schools — but the ranking is the least interesting thing on this page.

The headline number: 56.1% of students scored in the top band on the state test. The California average is 21.3%.

The school's 5th graders aren't posting a wider lead than its 3rd graders. One question worth asking on a tour: are the strongest students being pushed, or coasting? A school visit and conversation with teachers will tell you more than this number.

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 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.

Frequently asked questions

Is Carlton Elementary a good elementary school?

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 Carlton Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 76.5% of students at Carlton Elementary met or exceeded the state standard in ELA and Math combined, and 56.1% exceeded it. The gap between those numbers matters: 20.5% of students are at the proficiency floor, while 56.1% 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. 636 student-subject combinations were assessed.

How does Carlton Elementary rank in California?

Carlton Elementary ranks #389 among California elementary schools by Scope Score, placing it in the 93rd 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 Carlton Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Carlton Elementary decreases by 4.5 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 Carlton Elementary?

2.8% of students at Carlton 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 1.0%, 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.
