Schools do get an income based on attendance, but, it is not daily attendance. Either the kid is deemed as a student of that school or they are not. If a kid is absent 10% of the time, it does not take 10% of the income away.

Something I learned while working as a teacher was that if a child is seen on campus, it counts towards their attendance. They used to have "runners" which were school officials who would "catch" kids who were ditching, and run them to the other side of the school, doing that would make the kids run through campus, and then their attendance would be counted.

That was when I lost respect for the whole attendance thing. I will make sure my children are there enough so the school can get the compensation they need for teaching my children, but I am not bringing an unwell child to school.

Thank you for commenting, I appreciate knowing that this happens in Texas and that the crazies go beyond California.
