Chronic Absenteeism – School-by-School Listing  – Chronic Absentee Maps ( ):Elementary | Middle | High |
Overview
The state of California funds school districts based on student attendance, also known as Average Daily Attendance (ADA), at school. ADA is calculated by dividing the total number of days of student attendance by the number of days of school taught during the same period.
Example:
Michael has perfect attendance, calculated this way:
142 days attended ÷ by 142 days of school taught = 1.0 ADA
Hannah attended 136 of the 142 days taught, calculated this way:
136 days attended ÷ by 142 days of school taught = .96 ADA
How Does ADA Generate Revenue for the District?
A student like Michael, with perfect attendance, generates $5,786* in revenue for the district. It is calculated this way:
1.0 ADA x $5,786 revenue limit per ADA = $5,786.
A student like Hannah, who may miss several days, generates less revenue. In this case, ADA is calculated this way: .96 ADA x $5,786 revenue limit per ADA = $5,554
In this case, there was a loss of $232 in possible revenue.
Irregular attendance also affects the revenue the district receives from the lottery, and for Special Education.
Lottery
1.0 ADA x $118 = $118
.96 ADA x $118= $113
Special Education
1.0 ADA x $643= $643
.96 ADA x $643 = $617

What are the financial effects of lost ADA revenue?
If all students attended daily, the district would have approximately 117,556 students (excluding Charter Schools) counted toward ADA. When ADA drops, revenue dips accordingly.
| Perfect Attendance | 117,556 x $5,786 = | $680,179,016 |
| Estimated ADA at 95.0** | 117,556 x $5,786 x 95.0% = | $646,225,032 |
| Lost Revenue | $33,953,984 | |
* Estimates for 2007-08 as of 3/13/08
** Data is according to 2007-08, the most current year for which data is available. This figure is averaged, as different grade levels and different tracks generate different rates of ADA.
