Each gap is to the same group, grades and subject: in Los Angeles County Office of Education, and across California. None is green: no group that is behind statewide does 10 or more points better here than the same group statewide.
Low-income and Hispanic or Latino students and students with disabilities: fewer than 30 tested here. No published rate here for Asian, Black or African American, Filipino, American Indian or Alaska Native, Pacific Islander, homeless and military-family students, students of two or more races, English learners and foster youth. That can reflect privacy rules or small numbers; it isn’t evidence of a gap. This table covers groups by income, race or ethnicity, language and disability; girls and boys aren’t split out.
Read the student-group results as sentences
At Odyssey Charter in Altadena, 61.5% of low-income students (CDE’s “socioeconomically disadvantaged” group) met or exceeded the ELA standard in 2025 for reported grades 6 and 8, compared to 37.2% statewide for those same grades. Other subgroups: low-income students (23.1% met or exceeded the Math standard); White students (83.7% met or exceeded the ELA standard).

CDE reports scale-score points versus its growth-model prediction — 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 categorised” means this imported CDE row has a growth value without a performance category. CDE labels at least one imported estimate here WEIGHTED; that describes its aggregation method, 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. SchoolScope does not use these CDE figures in its Scope Score.

Source notes. CDE reports scale-score points versus its prediction for matched students, never a percentage. Among SchoolScope's retained California elementary school records, the median ELA estimate is +2 and the middle half fall between −5 and +9 scale-score points — the spread is wide, so read its position among reported schools, not the sign. 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 and is not part of the Scope Score.

ShowHide 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.
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.

Source: U.S. Census Bureau, American Community Survey, 2020–2024 5-year estimates. Median household income covers the past 12 months and is reported in 2024 inflation-adjusted dollars. Bachelor's degree or higher uses adults age 25 and over as its population. A dash is unavailable, not zero; a reported zero remains zero. ZIP/ZCTA context does not establish the school's attendance area or describe its enrolled students. These figures are not part of the Scope Score.
