One dot per school. Each stage is placed only among California schools at its own level. 5 of the 33 ranked schools teach two levels, so they appear in more than one picture.
The average elementary school in Ontario-Montclair had 8 in 100 students chronically absent (missed 10% or more of school days) in 2025–26; the average California elementary school we score had 17 in 100. Both are averages of school rates, each school counted once.

Figures from CDE’s state test, chronic absence and suspension files. Test figures cover every grade the district tests (California tests grades 3–8 and 11), so they differ from a profile’s rated grades. We combined the district’s schools ourselves, weighted by students and leaving out charter schools. Chronically absent means a student missed 10% or more of school days.
