Blackford Elementary: The scores are below where anyone wants them. Here's what they don't tell you.

Blackford posts low test scores — and test scores are one lens among several. If this is your zoned school, the numbers below are where to start a conversation, not where to end one.

Blackford 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 “21% proficient” and call it done. Blackford deserves a closer read. The school sits in San Jose, where more than half of 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.

As a charter, Blackford enrolls by application rather than address. That changes how you get in, but it doesn't change the score.

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.

On the state's science test (CAST), 12% met or exceeded the standard — science is tested in grades 5 and 8 but never enters the Scope Score.

Frequently asked questions

Is Blackford Elementary a good elementary school?

Blackford Elementary has a Scope Score of 30 out of 100, placing it in the 16th percentile of California elementary schools and ranked #4,823 statewide. 5.2% of students exceeded the state standard on the 2025 CAASPP assessment, which is 16.1 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 Blackford Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 21.4% of students at Blackford Elementary met or exceeded the state standard in ELA and Math combined, and 5.2% exceeded it. The gap between those numbers matters: 16.3% of students are at the proficiency floor, while 5.2% 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. 357 student-subject combinations were assessed.

How does Blackford Elementary rank in California?

Blackford Elementary ranks #4,823 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 Blackford Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Blackford Elementary decreases by 6.9 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 Blackford Elementary?

20.2% of students at Blackford Elementary are chronically absent (missing 10% or more of school days), compared to the California average of 17.9%. The suspension rate is 2.5%. 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 Blackford Elementary compare to other schools in San Jose?

Blackford Elementary scores 30/100 (16th 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 414 students.

Subgroup data is context, not part of the Scope Score: we don't penalize schools for who they serve. See our equity approach.
