Delta Home Charter: attendance

0 empty seats, every school day.

On an average day in 2024–25, about 0 of Delta Home Charter's 265 students were not in school. The state pays for students who attend, so those empty seats were worth about $0k that year.

Enrolled, but not in school

Each bar is everyone enrolled that year. The blue part is how many were in school on an average day; the red part is how many were not.

Numbers on the bars: students absent on an average day. 2019–20 has no attendance data (COVID); 2020–21 was mostly distance learning.

What the empty seats are worth

California pays a district or charter school for each student in school on an average day (its Average Daily Attendance, or ADA). Each empty seat, valued at that year's dollars per ADA:

Hatched years: the state froze or protected attendance funding during COVID, so absences that year did not cut the money. Since 2022–23 a district is paid on the best of this year, last year or a three-year average, which softens a fall but also delays a rise.

What better attendance would bring

Attendance rate is the share of enrolled students in school on an average day. Move the slider to a higher rate: how many more seats would be filled, and what would it receive?

Attendance rate: 102.0%

Already above New Jerusalem Elementary average (94.5%), San Joaquin County average (92.6%), and California before COVID (94.6%).

$65kmore attendance funding a year, at 2024–25 rates

Delta Home Charter's attendance rate in 2024–25 was 100.0%. Each point is worth the same wherever it starts, since it is a point of every enrolled student's days. A charter school is paid on the year's own attendance, so a gain reaches its budget the same year.

Who is missing

Absence by grade

Share of students chronically absent (missing 10% or more of the days they were enrolled), by grade, 2024–25:

Kindergarten tends to run high for reasons usually put down to young children's health, transport and families' routines. A steady climb from grade 4 to grade 12 is the pattern discouragement would leave: absence that builds as students fall further behind.

Some students carry far more of it

Groups too small for the state to report are left out. Foster youth and homeless students point to the transport, housing and family pressures outside school. They are real, and no school model removes them on its own.

Behind, and staying away

Each dot is a school in New Jerusalem Elementary; Delta Home Charter is the one ringed in black. Across, how far its students were from the state's math standard in spring 2025; up, the share chronically absent in 2024–25. Colour is the share of students from low-income families.

10 schools with at least 50 students. Correlation between math results and chronic absence: −0.40 across all of them; −0.42 leaving out the 2 alternative schools. Dot size: enrollment. Hover a dot for the school.

What this does and doesn't show. Where students are furthest behind, absence runs highest. Where the link holds among places serving almost entirely low-income families, it isn't only family income. It fits the idea that discouraged students stay away. It can't show which comes first: missing school also puts students behind. Proving the direction is what the sponsored schools are for.

Students who left

Delta Home Charter has 71 more students than in 2014–15. Its district, New Jerusalem Elementary, has 24.0% fewer. Had Delta Home Charter changed at the district's pace it would have about 147; it has 265. A school's enrollment also moves with boundaries, programs and new schools nearby, so read this as a prompt to ask why rather than as a verdict. It has kept pace, so the opportunity is students who are enrolled and not coming.

How we worked it out

Absent on an average day = every day of school missed by every student that year, divided by 180 school days. In school = census-day enrollment minus that. For 2024–25 this gives about 265 students in school on an average day, against the 257 ADA the state funded.
Attendance rate = students in school on an average day ÷ students enrolled.
Dollars per ADA = LCFF revenue that year divided by funded ADA, from CDE's LCFF Summary Data: the charter school's own. It includes the extra grants for low-income students and English learners, so it is what an added student brings, not the statewide base rate.
Years. The absence collection began in 2017–18, and some districts' figures jump the next year in a way that looks like a change in recording, so this page starts in 2018–19. 2019–20 has no attendance data (COVID). 2020–21 was mostly distance learning, when attendance meant something different.
Chronically absent is CDE's measure: a student who missed at least 10% of the days they were enrolled.
