I can second it, having gone through the Texas public education system. The standardized testing regime in Texas is completely counterproductive, and my teachers all hated it. Texas' silly education funding system that tied funding to (among other things) student attendance caused the schools to overtly encourage sick kids to show up and spread disease. The attempt by the Bush administration attempt to deploy Texas standards nationwide in the form of No Child Left Behind was a miserable failure. The legislature is constantly playing games with the schools (e.g. putting ambiguous language in the teaching standards to appease creationists [1]).

Texas has decent K-12 education in spite of everything the government does, not because of it.
