Progress
Lower, in both subjects. In 2025, students here in grades 7 and 8 scored 50 points lower in English than California students who had the same score the year before. The state calls that Minimal. In math, they scored 24 points lower, which the state calls Minimal.

Grades 7 and 8, 2025, 32 students in English, 33 in math with scores in both years. Faded rows have fewer than 40 students. It describes results, not causes. Source: California Department of Education, growth model.
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 50 points below that expected score, and in math 24 points below it.
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.
Over time
English results were lower than in 2025; math results were similar. English went from 11% to 3% and math from 11% to 13%.

All Grades is an aggregate, not another group of students. Same-year grade groups are not matched children. 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.

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.

These figures are not directly comparable: school ESSA attributed spending and NCES district current expense use different measures and populations. Their fiscal years are labeled above.
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 $7,727,575 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.
