What the empty seats are worth

California pays a school's district 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 San Mateo County Office Of Education receive?

Already above San Mateo County Office Of Education average (85.8%), San Mateo County average (94.1%), and California before COVID (94.6%).

Who is missing

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.

Students who left

Hillcrest At Youth Services Center has 58 fewer students than in 2014–15. Its district, San Mateo County Office Of Education, has 80.8% fewer. Had Hillcrest At Youth Services Center changed at the district's pace it would have about 14; it has 16. 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 16 students in school on an average day.
  • 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: San Mateo County Office Of Education's, since the district is paid for its schools' students. 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.
  • Sources: California Department of Education: Absenteeism by Reason and Chronic Absenteeism (DataQuest downloads), Census Day Enrollment, LCFF Summary Data, CAASPP research files and Free or Reduced Price Meal files.
