DALLAS -- Dozens of Texas schools appear to have cheated on the state's redesigned academic achievement test, casting doubt on whether the accountability system can reliably measure how schools are performing, a paper found.

An analysis uncovered strong evidence of organized, educator-led cheating on the Texas Assessment of Knowledge and Skills at schools in Houston and Dallas, along with suspicious scores in hundreds of other schools, the Dallas Morning News reported.

Texas education policies on student accountability became the model for the federal No Child Left Behind law enacted after President Bush's election in 2000.
