People want to point the finger at all kinds of things, but the truth is that school performance is based on the intelligence of the students.
Smart people create/nurture smarter and more driven kids. Smart people tend to live around each other, so their kids go to the same schools, and so those schools do better. Smart people tend to be more successful, so they are wealthier, so it looks like money has something to do with it, but it doesn't, its just a correlation.
There are smart people/kids in poor areas, and those kids tend to find their way out, even though their school is low rated because its full of less intelligent (dumb) kids. There are dumb kids that live in wealthy areas, and those kids dont do well in the high-rated schools and so they tend to find their way out of the wealthy areas.
In Austin, there are a few areas where smart people live:
- Eanes
- Lake Travis
- Western Round Rock
- Leander/Cedar Park
- Dripping Springs
- Central Austin
- Southwest Austin
- Northwest Hills
The schools in these areas do better. Some of it is AISD, most of it is not. Some of those AISD areas have parents who ship their kids to a private school, to be around other smart kids, so the school quality suffers because they lose the kids on the higher end of the bell curve.
In Austin, there are also the noble gentrifiers, who, while smart, consider it their personal, social mission to move to poor areas in hopes to influence the areas to do better. It doesnt really work, because the area is still full of dumb people.
People are not created equal. Some are smarter than others. I grew up in Westlake, surrounded by the cream of the crop. There were kids in that school who were crazy smart, and they usually had smart parents who were professors or engineers, etc. 20 years later, those kids are all doing just fine. There were also some dumb kids at Westlake. Those kids aren't as successful, they dont live in Westlake anymore. We all went to the same school, and had the same opportunities.
