Vista Del Mar Union: attendance

5 empty seats, every school day.

On an average day in 2024–25, about 5 of Vista Del Mar Union's 65 students were not in school. Vista Del Mar Union is a basic aid district, funded by its own property taxes, so its revenue depends little on attendance.

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?

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

Vista Del Mar Union's attendance rate in 2024–25 was 92.5%. Each point is worth the same wherever it starts, since it is a point of every enrolled student's days. Vista Del Mar Union's funded ADA is close to its actual attendance, so a gain should reach its budget soon rather than being absorbed by the three-year protection. That is an estimate worth checking with the district.

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.

Why days are missed

Of the days Vista Del Mar Union students missed in 2024–25, 34% were unexcused, 66% excused (illness, appointments), 0% were independent study work not completed, and 0% were suspensions. In 2018–19, before COVID, 37% were unexcused. Unexcused absence, where no reason is given, is the kind most likely to reflect a student choosing not to come.

Students who left

Vista Del Mar Union has 53 fewer students than in 2014–15. California as a whole has 6.9% fewer, mostly because of the falling birth rate. Had Vista Del Mar Union changed at the state's pace it would have about 110; it has 65. About 45 more students than that trend have left, worth about $2.1M a year.

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 60 students in school on an average day, against the 30 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 district'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.
