One more thing to know

On spring 2025 tests, students in grades 6–8 scored higher than California students who had the same scores the year before, in English (+13 pts) and math (+37 pts). The state calls them Accelerated in English and Exceptional in math.

Each bar is Richardson PREP HI’s place among 2,529 California public middle 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 6–8. 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.

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 13 points above that expected score, and in math 37 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 8 scores here with the school’s grade 6 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 middle standardized cohort gain: approximately 93rd 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.

Index is where the school's value sits among the California middle 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.

Grade gap: the same year’s grade 6 and grade 8 results, side by side. They are different children, so the gap describes one year, not any child’s progress. The Scope Score’s growth measure is a different comparison, shown in Score factors above (how it’s built).

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 6–8. 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 middle school records, the median English estimate is −2 and the middle half fall between −10 and +5 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 6–8, 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 $1,082,327,441 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.
