One more thing to know

74 of 339 students missed 10% or more of school days in 2025–26, against 37 in 100 at the average West Contra Costa Unified elementary school.

Each bar is Ellerhorst’s place among 5,726 California public elementary schools we score. Our calculation from California Department of Education records, updated October 15, 2026.

How to read these bars, and their sources

A place counts the schools out of 100 with a lower figure. The dashed line is the middle. Test results are from spring 2026, grades 3–5. Progress is the state’s measure of how the same students’ scores changed against the score it expected, 2025. Attendance counts students who missed 10% or more of school days; fewer is better, so a higher place means fewer such students.

Did students here score higher than students who started at the same place?

In English, about the same. In math, yes. In 2025, students here in grades 4–6 scored 2 points lower in English than California students who had the same score the year before. The state calls that Average. In math, they scored 6 points higher, which the state calls Accelerated.

How the state’s growth measure works

The state calls this comparison an expected score. It sets one for each student from that student’s own score the year before.

California uses each student’s English and math scores from the year before to set an expected score, based on how students with similar earlier scores did across the state. Zero would mean students here scored as expected. In English they scored 2 points below that expected score, and in math 6 points above it. Unlike the growth in our Scope Score, it follows the same students from one year to the next.

The state sorts every school’s growth result into five growth levels, from Minimal to Exceptional.

Here, as at most schools, the state’s figure blends the two most recent years, so it moves more slowly than one year’s scores.

Our Scope Score measures growth another way. It compares the latest grade 5 scores here with the school’s grade 3 scores two years earlier (partly different children), then places that change among California schools at the same level. The state’s measure counts only students who took California’s test the year before, so the two can point different ways.

SchoolScope elementary standardized cohort gain: approximately 43rd percentile on a calibrated reference scale, not an empirical school rank. This score compares school-level grade groups across English and math, not matched students in California's separate growth model.

The group is every California public elementary school we score where 53% to 65% of students qualified for free or reduced-price meals in 2024–25. That is within 6 points of Ellerhorst’s share. The count includes Ellerhorst. Typical means the median: half are higher and half are lower. Schools differ in more than family income, and no score is changed for it.

A grade the school doesn't teach has no row. “Suppressed” marks a result CDE blanks because fewer than 11 students tested (CDE’s reporting rule); “none tested” marks a grade CDE lists with no students tested; “not on file” marks a result missing from the records we hold. None of them means zero.

What you can do

Who can act on Ellerhorst’s results?

West Contra Costa Unified’s board decides Ellerhorst’s plan.

When the plan is set

West Contra Costa Unified’s board must adopt its yearly plan (LCAP) by July 1, after at least one public hearing at an earlier meeting.

Read the 2026–27 plan (LCAP, PDF)

How to take part

  1. Watch the board’s agenda: the hearing is posted at least 72 hours ahead.
  2. Send written comments on the actions and spending the plan proposes.
  3. Raise questions through the district’s parent advisory committee; the superintendent must answer its comments in writing.
  4. Read the midyear report, due by February 28.

Extra state help for the district

The state is giving West Contra Costa Unified extra help in 2026. It qualified on the 2025 and 2026 California School Dashboards. The 2026 Dashboard flagged results for long-term English learners on two measures: English, and progress in learning English. The county office must help the district for at least three years, including a review of its yearly plan.

Reading screening in kindergarten through grade 2

California law requires schools to screen kindergartners through second graders for reading difficulties every year, with some exceptions. You get notice at least 15 days before, results within 45 days, and can opt out in writing.

Kindergartners can’t be screened before the 91st school day; transitional kindergarten isn’t covered.

If screening shows your child may be at risk for reading difficulties, the school must provide supports. That result isn’t a diagnosis, and screening can’t be used to delay a special-education evaluation.

Ask how many K–2 students screening found at risk last year, and how many got extra reading help.

The road from this school ends at Pinole Valley High. UC records 29 enrollees from Pinole Valley High for fall 2025. The AP Course Audit lists 4 AP courses its teachers are authorized to teach in 2025–26. Those figures come from dated records. A child starting here today would reach Pinole Valley High around 2036, and a school can change a lot in 10 years. By the state’s 2023 count, 74% of the students who finished high school at Pinole Valley High enrolled in college within 12 months, UC or not.

Index is where the school's value sits among the California elementary schools we score, from 0 to 100, where 50 is their average; it is not a percentile. School values are from 2025–26. Chronic absence and suspension are CDE's all-students school rates; the score uses an adjusted version of each that pulls small schools toward the average, so their index can sit nearer 50 than the rate suggests. Growth is the change between the school's earlier and later grade-level groups, in scale-score points; it does not follow the same students.

CDE reports scale-score points against the state’s expected score — not a percentage or percentile. The table keeps the group records SchoolScope imported for this school, including rows below our narrative display threshold. Muted rows have fewer than 30 students with a valid growth score. SchoolScope uses that threshold for the shorter narrative view; the reported values stay visible here. “Not categorized” means this imported CDE row has a growth value without a performance category. At least one estimate here is a CDE weighted estimate; that describes how CDE combines years, not a year-over-year trend. A group absent from this table has no imported record shown here. Its absence alone does not establish its size or performance. CDE growth covers grades 4–8; here that is grades 4–6. SchoolScope does not use these CDE figures in its Scope Score.

Source notes. CDE reports scale-score points against the state’s expected score for matched students, never a percentage. Among SchoolScope's retained California elementary school records, the median English estimate is +2 and the middle half fall between −5 and +9 scale-score points — the spread is wide, so read the figure against it, not its sign alone. CDE's 2025 Dashboard weighted school estimate uses assessments from 2022–23, 2023–24, and 2024–25; adjacent reporting editions should not be read as independent annual changes. The CDE measure covers grades 4–8; here that is grades 4–6, and it is not part of the Scope Score.

How the California mean was selected

SchoolScope starts with its selected California finance records, not every NCES California district. For FY 2020–21, it calculates an unweighted mean of NCES F-33 current expense per pupil. District records contribute once, regardless of enrollment. The calculation keeps records with positive per-pupil current expense, enrollment over 100, CCD agency type 1, and a recorded district name; it excludes names ending in County Office of Education, Department of Education, or Superintendent of Schools. This is a SchoolScope calculation, not a state-published spending average.

These shares are our arithmetic: each group’s dollars divided by the $515,956,588 total of the groups shown, rounded to whole percents by largest remainder so they add up to 100. Dollar amounts are rounded to the nearest dollar, so they can differ from the total by a dollar. SchoolScope groups district-level CDE SACS UserGL actuals from Fund 01, using operating objects 1000–5999 and excluding retiree benefits, food and community services, facilities acquisition, other outgo, and nonagency goals. These shares use that filtered total; they do not exactly break down CDE's official current expense per ADA above. The school-level ESSA figure uses a separate source.
