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

Discovery posts low test scores — and suspensions run below the state rate (0.9% vs 1.6%). If this is your zoned school, the numbers below are where to start a conversation, not where to end one.

ranked #4,705 statewide · #6 of 16 in Lancaster Elementary

Discovery scores 31 of 100 on SchoolScope's Scope Score — the 18th 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 “24% proficient” and call it done. Discovery deserves a closer read. The school sits in Lancaster, where four 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 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.

Worth Knowing

Transitional kindergarten is offered here — confirmed by actual Census Day enrollment, not just the listed grade span.

On the state's science test (CAST), 14% met or exceeded the standard — science is tested in grades 5 and 8 but never enters the Scope Score.

Frequently asked questions

Is Discovery a good elementary school?

Discovery has a Scope Score of 31 out of 100, placing it in the 18th percentile of California elementary schools and ranked #4,705 statewide. 8.0% of students exceeded the state standard on the 2025 CAASPP assessment, which is 13.3 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 Discovery's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 24.1% of students at Discovery met or exceeded the state standard in ELA and Math combined, and 8.0% exceeded it. The gap between those numbers matters: 16.0% of students are at the proficiency floor, while 8.0% 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. 661 student-subject combinations were assessed.

How does Discovery rank in California?

Discovery ranks #4,705 among California elementary schools by Scope Score, placing it in the 18th 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 Discovery getting better or worse?

Based on 2025 CAASPP data, proficiency at Discovery decreases by 5.4 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 Discovery?

23.3% of students at Discovery are chronically absent (missing 10% or more of school days), compared to the California average of 17.9%. The suspension rate is 0.9%, 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 Discovery compare to other schools in Lancaster?

Discovery scores 31/100 (18th 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 662 students. Use the schools in Lancaster page or the map view to compare all elementary schools nearby.

How does Discovery serve low-income and underrepresented students?

At Discovery in Lancaster, 26.1% of low-income students met or exceeded the ELA standard in 2025, compared to 22.6% district-wide and 38.2% statewide. Discovery outperforms its district average for low-income students by 3.5 percentage points in ELA. Other subgroups: Low-Income students (20.6% Math proficient); Hispanic students (27.3% ELA proficient). The largest proficiency gap is 21.2 percentage points for disabilities students. Data source: California Department of Education, CAASPP 2024-25. 295 students tested. 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.
