Since Edgewood v. Kirby, what is true about school funding in Texas?

The correct answer identifies that wealthy districts in Texas can provide additional funds. This reflects the ruling in Edgewood v. Kirby, which aimed to address disparities in school funding across the state. The Texas Supreme Court's decision acknowledged that while the state's funding system was inadequate in some respects, it did allow for some wealthier districts to supplement their funding beyond the state's basic allocation. This means that despite efforts to equalize funding, wealthier districts can still enhance their financial resources for schools through local property taxes and other means.

In the context of the other options, saying that all differences have been eradicated or that there is no disparity in funding misrepresents the ongoing issues related to equity in education funding. While the ruling did improve the situation, significant differences remain. The assertion that school funding remains unconstitutional misses the context of ongoing adjustments and reforms following the court's decisions. Therefore, the ability of wealthier districts to provide additional funds remains a key aspect of the current school funding landscape in Texas.
