The same students do better at charter schools than when they go to a public school though. So it's not just selection bias. Getting away from the masses that have no interest in education is just as important in some places.
Sure, that's something that a public school -- bound by law to include everyone -- can't do, but it's no reason to drag others down into the mess that is public schools.
- jedberg 13y agoSelection bias. The poor performers that move schools do so because they have involved parents, and involved parents are the #1 indicator of success in school.
- beat 13y agoIt's not just selection bias, though. Charters, having distinctive education styles, will be more appropriate for some students and less appropriate for others. The other layer of "selection bias", then, is that parents/children will be more inclined to charters that seem more suitable for their own needs. For example, in MN, we have a number of Somali-language bilingual charters for our massive Somali immigrant population. Fantastic option for Somali immigrant kids. Not so fantastic for other kids. That's not just selection bias on parental involvement, that's appropriate environment for the kids' needs.
- LanceH 13y agoNot just selection bias. Look up how some of them are selected, through lottery. Involved parents sign up kids for the lottery and they end up going to either school randomly. The kids getting into charter schools show more improvement than those going to public schools. Both groups probably outperform their peers in their individual schools. You could argue that charters have a selection bias for more passionate teachers and staff, but that's kind of proving the point of the charter schools.
