CDE CAASPP 2025

Most rating sites would stop at “85% proficient” and call it done. Richardson PREP HI deserves a closer read. Four in five of its students qualify for free or reduced lunch (California: 64%) — and reading the numbers without that context misreads the school.

Richardson PREP HI's low-income kids hit 85.1% proficiency in ELA — a number the same group reaches at 38.2% statewide. If you're trying to read past zip-code-driven test scores, that's the signal worth weighing.

California's own answer to the same question

Context — never part of the Scope Score

California runs its own growth model, following individual children in grades 4 through 8 rather than comparing school-wide averages the way we do. The two measures land in the same neighbourhood here — ours puts this school around the 94th percentile of California middle schools, the state's around the 93rd in reading and math together. Two different methods agreeing is the most you can ask of one year of test data.

this school| the tick is the middle of the California field

— pts vs expected is scale-score points above or below what California's model predicted for these same children from their own prior-year scores. It is not a percentage and not a percent of anything. A typical California middle school lands at −1 in reading, and the middle half of them fall between −8 and +6 — the spread is wide, so read the rank, not the sign. CDE blends two consecutive years into each published figure, so adjacent years share input data and no year-over-year trend can honestly be drawn from them. It covers grades 4-8 only, and it is not part of the Scope Score — we assessed it and left it out: it tracks school demographics roughly three times as strongly as our own growth measure does, and one published year is not enough to test how stable it is.

Worth a school visit

Ask what changed — new curriculum, new principal, new program. Momentum has a cause, and a visit will find it.

  • Ask how teachers track each child's growth over the year, not just where the class lands on test day.
  • Ask whether extra support — tutoring, counseling, small groups — reaches kids across income lines, not just the students already ahead.
  • 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.

California follows these children individually and predicts each one's score from their own prior year. Each row is read against the same group at a typical California middle school — not against zero, and not against this school's all-students figure, because the state's expectation already differs by group.

— 6 more groups are reported here with between 11 and 29 students. We hold those back on purpose: at that size the figure swings about 17 points on its own, and a quarter of such groups land past the state's top or bottom cut point by chance alone. They are listed with their student counts in the data appendix. — A group not listed at all had fewer than 11 students with a growth score, so California published nothing for it here. That is a privacy protection, not a judgment about those students. — Context only. None of this enters the Scope Score.

Frequently asked questions

Is Richardson PREP HI Middle a good middle school?

Richardson PREP HI Middle has a Scope Score of 83 out of 100, placing it in the 98th percentile of California middle schools and ranked #38 statewide. 47.2% of students exceeded the state standard on the 2025 CAASPP assessment, which is 30.0 percentage points above the California average of 17.2%. The Scope Score weights 6 dimensions for middle schools: exceeded standard (42%), met or exceeded (proficient) (23%), grade 6-to-8 growth (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 Richardson PREP HI Middle's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 85.3% of students at Richardson PREP HI Middle met or exceeded the state standard in ELA and Math combined, and 47.2% exceeded it. The gap between those numbers matters: 38.1% of students are at the proficiency floor, while 47.2% went beyond it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it shows how many students go beyond the standard rather than only meeting it. 1,144 student-subject combinations were assessed.

How does Richardson PREP HI Middle rank in California?

Richardson PREP HI Middle ranks #38 among California middle schools by Scope Score, placing it in the 98th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), same-cohort growth (2023 G6 → 2025 G8), 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 Richardson PREP HI Middle getting better or worse?

SchoolScope follows the same cohort of students across grades rather than comparing two different grades in the same year. At Richardson PREP HI Middle that cohort is 2023 G6 → 2025 G8, measured in SBAC scale-score points. Its gain ranks strong among California middle schools — roughly the 94th percentile, ahead of the typical school at this level. Read the ranking, not the raw point gain: scale scores rise with age, so nearly every school posts a positive number and only the relative position tells you anything. Growth is weighted at 20% in the middle Scope Score because it is the least demographically confounded signal available — it tracks change over time rather than the level students arrived at. See full methodology.

What is the attendance and school culture like at Richardson PREP HI Middle?

4.5% of students at Richardson PREP HI Middle are chronically absent (missing 10% or more of school days), which is better than the California average of 18.1%. The suspension rate is 3.2%. 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 Richardson PREP HI Middle compare to other schools in San Bernardino?

Richardson PREP HI Middle scores 83/100 (98th percentile) among California middle 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 583 students. Use the schools in San Bernardino page or the map view to compare all middle schools nearby.

How does Richardson PREP HI Middle serve low-income and underrepresented students?

At Richardson PREP HI Middle in San Bernardino, 85.1% of low-income students met or exceeded the ELA standard in 2025, compared to 34.5% district-wide and 38.2% statewide. Richardson PREP HI Middle outperforms its district average for low-income students by 50.7 percentage points in ELA. Other subgroups: Low-Income students (83.8% Math proficient); Hispanic students (86.3% ELA proficient). The largest proficiency gap is 4.3 percentage points for white students. Data source: California Department of Education, CAASPP 2024-25. 505 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.

Whole scale-score points above or below what CDE's model predicted for these same children from their own prior-year scores — not a percentage, not a percentile. Statewide a typical school lands near +1 with a spread of about 13 points either side, so read a figure against its group's own typical value, not against zero. Muted rows have fewer than 30 students with a growth score — published by CDE, held back from the narrative sections above because at that size the figure swings about 17 points on its own. “Not categorised” is CDE assigning no band — English Only, Recently Reclassified, and English Learners Only receive a value and no band, for every school in the state. It is not a missing number. Most figures blend two consecutive years, so adjacent published years share input data and no trend line can honestly be drawn across them. A group absent from this table had fewer than 11 students with a growth score and was never published. Grades 4-8 only. None of this enters the Scope Score — it is more strongly correlated with school demographics than our own growth measure, and one published year is not enough to test its reliability.
