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.

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 9 points below that expected score, and in math 11 points above 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.

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.

State support

The state hasn’t placed Marcum-Illinois Union Elementary in a support program. Federal designation under the Every Student Succeeds Act, 2025–26. Source 

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.

Grade gap (G3→G5, different students)-14.3pp—not scored

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. The weights above add to 80%: the remaining 20%, for measures with no value here, is shared out among the measures above.

Chronic absence and suspension are CDE’s all-students school rates for each year.

Grade gap: the same year’s grade 3 and grade 5 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).

Current 2025–26 grade results are under Academic achievement, in Results for each grade. “Students with scores” counts the students tested in that grade, subject and year. A missing result is not zero, and each year’s row is a different group of children.

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. 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, 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 $3,120,940 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.
