Liberty Charter: english

The shaded band is this school's normal range. If nothing about how it works changes, nearly every future year should land inside it. Zero means the typical student just meets the state standard. The small numbers under the years are how many students were tested.

Measured against the grade bars

The state's English test uses one scale for every grade, so a score means the same thing in grade 3 as in grade 8.

Many students here are still learning English, and this test is given in English. In 2026, 168 of the 467 students who took the English Language Arts test were English learners.

All students

3rd The average 3rd grader scores 49 points under the grade 3 bar. 2383 vs. 2432.
4th The average 4th grader scores 37 points under the grade 3 bar. 2395 vs. 2432. The 4th-grade bar is 2473.
5th The average 5th grader scores 27 points under the grade 4 bar. 2446 vs. 2473. The 5th-grade bar is 2502.
6th The average 6th grader scores 15 points under the grade 4 bar. 2458 vs. 2473. The 6th-grade bar is 2531.
7th The average 7th grader scores 22 points under the grade 6 bar. 2509 vs. 2531. The 7th-grade bar is 2552.
8th The average 8th grader scores 17 points under the grade 6 bar. 2514 vs. 2531. The 8th-grade bar is 2567.

Students fluent in English

The closest these results come to reading alone: English is not in the way. Includes students who have only ever spoken English.

Grade bars 3rd 47 students 33 points under the grade 3 bar. 4th 41 students 37 points under the grade 4 bar. 5th 54 students 29 points under the grade 5 bar. 6th 46 students 17 points under the grade 5 bar. 7th 61 students Just under the grade 6 bar. 8th 50 students 12 points under the grade 8 bar.

English learners

Students leave this group as they become fluent, so its average stays low even where they learn well.

Grade bars 3rd 28 students 76 points under the grade 3 bar. 4th 35 students 85 points under the grade 3 bar. 5th 23 students 48 points under the grade 3 bar. 6th 37 students Just under the grade 3 bar. 7th 22 students 19 points under the grade 4 bar. 8th 23 students Just under the grade 3 bar.

the group's average that grade's own bar the distance between

2026 results. The English test covers reading, writing, listening and research together. "Meets standard" is the state's mark for being on track for that grade. The state leaves out any group of ten students or fewer, so a grade may be missing from the charts.

Step 1 · Each year's result

For each grade tested, take the average (mean) scale score from the California Department of Education's results file, and subtract the lowest score that counts as "Standard Met" for that grade. That is the grade's distance from standard. Weight each grade by its share of the students tested, then add the grades up. Grades where the state hides the average because ten or fewer students tested are left out entirely.

Step 2 · The average and the normal range

Average: add the yearly results and divide by how many there are. −50, −42, −58, −45, −54, −62, −71, −73, −62, −59 → −57.6
Typical year-to-year change: how far the result moved from each year to the next, ignoring up or down. 2015→2016: 8 · 2016→2017: 16 · 2017→2018: 13 · 2018→2019: 9 · 2019→2022: 8 · 2022→2023: 9 · 2023→2024: 2 · 2024→2025: 11 · 2025→2026: 3 → average 8.8
Normal range: multiply the typical change by 2.66, then add it to the average and subtract it. 8.8 × 2.66 = 23.4. Upper limit −34.2, lower limit −81.

Why 2.66? It is the standard factor from quality control, the work of Walter Shewhart and W. Edwards Deming. It turns "how much the result typically changes in a year" into "how far it can wander by chance alone".

Years with no result (no state tests were given in spring 2020) are skipped: the year-to-year change runs from the last year with a result to the next one.

Step 3 · Free or reduced-price meals

The share of enrolled students eligible for free or reduced-price meals. From 2014–15, 2015–16, 2016–17, 2017–18, 2018–19, 2020–21, 2021–22, 2022–23, 2023–24, 2024–25, 2025–26.
