How much does school funding play into this dynamic? Local property taxes account for a large portion of public school funding, resulting in very different experiences for students depending on where they live.
Funding doesn't play much - throwing money at the problem has been shown not to fix the problem. Some kids just aren't interested in learning or putting the effort in to do so.
I agree that property taxes are way too high, at least in my state where they are among the highest rate in the country. More of the cost of education should come from the parents themselves rather than putting that burden on the rest of the community through higher property taxes.
Basically the strongest correlation with achievement and test scores in school is the wealth of the parents. Poor kids don't learn as well, for a large variety of reasons. These may include, but aren't limited to:
- being homeless
- living in a home with multiple families (no place to sleep/study)
- having parents who work multiple jobs and cannot help with homework
- having parents who do not speak English
- no books in the house
- being hungry
- being kicked out at 18, or made to take a job to help the family
- having no example of what education can do for you
So. How is this related to school funding? It's actually fairly well correlated when you consider how the poorest of the students do. If you have a wealthy school district, where the average $ spent per student is $22k a year, then what you have is a student body that is predominantly wealthy. The small percentage of poor students (say, the gardener's kid, the maid's kid) get a lot more help and attention because of the sheer amount of money spent per student. Smaller class sizes. More time spent on reading in the early years.
If you happen to be at a richer school in a more average district, this plays out in PTO donations. Schools that can raise $500,000 a year can use that money for reading specialists, music teachers, and smaller class sizes, so that maybe the slightly higher % of poor students get more attention.
If you have a school where a large % are poor, the school simply isn't going to get the $ from the PTO that they'd need to decrease class sizes, or hire the # of reading specialists in order to get the poorer students, who are further behind, up to grade level. The school will have to very carefully figure out how to allocate their budget to do the most with very little.
My experience in this area is as a parent in a poor-ish school, who has done fundraising for the PTO and has been on the school council for deciding how to spend district funds. I've also downloaded demographic and test score data from about 20 of the local elementary schools to do a somewhat statistical analysis of achievement compared to % of students in poverty or % of students who are EL. Turns out, the relationship was basically linear. While the EO and middle class kids do fine across the board, regardless of school - the EL and poor students do WORSE at the poorer schools. The greater % of students who are poor, the worse the overall and sub-group test scores are.
