Is it getting better · CAASPP 2019 to 2025

Has stayed near the 48th percentile since 2019.

Most rating sites would stop at “35% proficient” and call it done. Lydia Jackson College Preparatory Academy 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.

170 tested · 3 of 3 grades published · cohort of 49 tracked

Lydia Jackson College Preparatory Academy scores 35 of 100 on SchoolScope's Scope Score — the 48th percentile of 5,721 California elementary schools (CDE CAASPP 2025).

This school hasn't fully recovered from the pandemic: 35% meet the standard today, versus 43% in 2019 — a gap worth asking about on a visit.

California’s growth results and student groups
State growth model · CDE growth model 2024–25

Our growth read and California's own model disagree here — the 69th percentile against the state's 39th.

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 — and here the two measures disagree. Ours puts this school around the 69th percentile of California elementary schools; the state's puts it around the 39th in reading and math together — a harder read than ours. We are not going to pretend one of those is the answer. Neither measure sees an individual child's classroom, and a disagreement this size is worth asking the principal about directly.

— 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 elementary school lands at +2 in reading, and the middle half of them fall between −5 and +9 — 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.

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 elementary school — not against zero, and not against this school's all-students figure, because the state's expectation already differs by group.

— 4 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.

Worth a school visit

Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.

  • Ask how the school follows up when a student starts missing days — chronic absence often starts outside the classroom, not inside it.
  • 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.
Questions

Frequently asked questions

Is Lydia Jackson College Preparatory Academy a good elementary school?
Lydia Jackson College Preparatory Academy has a Scope Score of 35 out of 100, placing it in the 48th percentile of California elementary schools and ranked #2,994 statewide. 14.9% of students exceeded the state standard on the 2025 CAASPP assessment, which is 6.5 percentage points below the California average of 21.4%. The Scope Score weights 6 dimensions for elementary schools: exceeded standard (42%), met or exceeded (proficient) (23%), grade 3-to-5 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 Lydia Jackson College Preparatory Academy's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 35.5% of students at Lydia Jackson College Preparatory Academy met or exceeded the state standard in ELA and Math combined, and 14.9% exceeded it. The gap between those numbers matters: 20.6% of students are at the proficiency floor, while 14.9% 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. 342 student-subject combinations were assessed.
How does Lydia Jackson College Preparatory Academy rank in California?
Lydia Jackson College Preparatory Academy ranks #2,994 among California elementary schools by Scope Score, placing it in the 48th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), same-cohort growth (2023 G3 → 2025 G5), 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 Lydia Jackson College Preparatory Academy getting better or worse?
SchoolScope follows the same cohort of students across grades rather than comparing two different grades in the same year. At Lydia Jackson College Preparatory Academy that cohort is 2023 G3 → 2025 G5, measured in SBAC scale-score points. Its gain ranks above avg among California elementary schools — roughly the 69th 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 elementary 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 Lydia Jackson College Preparatory Academy?
23.8% of students at Lydia Jackson College Preparatory Academy 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 Lydia Jackson College Preparatory Academy compare to other schools in Whittier?
Lydia Jackson College Preparatory Academy scores 35/100 (48th 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 338 students. Use the schools in Whittier page or the map view to compare all elementary schools nearby.
How does Lydia Jackson College Preparatory Academy serve low-income and underrepresented students?
At Lydia Jackson College Preparatory Academy in Whittier, 37.1% of low-income students met or exceeded the ELA standard in 2025, compared to 43.0% district-wide and 38.2% statewide. Lydia Jackson College Preparatory Academy trails its district average for low-income students by 5.9 percentage points in ELA. Other subgroups: Low-Income students (30.3% Math proficient); Hispanic students (40.9% ELA proficient). The largest proficiency gap is 26.2 percentage points for disabilities students. Data source: California Department of Education, CAASPP 2024-25. 151 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.
What middle school does Lydia Jackson College Preparatory Academy feed into?
By attendance boundary, Lydia Jackson College Preparatory Academy is zoned to Walter F. Dexter Middle. Walter F. Dexter Middle has a Scope Score of 27 out of 100. Boundaries come from the U.S. Department of Education's School Attendance Boundary Survey, a 2015-16 collection and the most recent national one — they are approximate and may since have changed. A boundary is also not a placement guarantee: magnet, charter, open-enrollment and inter-district transfer options mean students from one school often continue to several different ones. Confirm your address with the district before making an enrollment or housing decision. Data source: NCES School Attendance Boundary Survey, analyzed by SchoolScope.

Grade gap = this year's grade 3 vs grade 5 result, two different sets of students, not a trend for any one child — it is not the measurement the Scope Score's growth dimension uses. See §01 above and /methodology#verdicts for the school's actual scored (cohort) growth.

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.
