Updated 1:28 p.m. to reflect that eleven states have already been granted waivers.
The Missouri Board of Education has approved the state's request for a waiver from some provisions of the federal No Child Left Behind law.
Members voted Tuesday to support the waiver's submission to the U.S. Department of Education with minor edits. Last fall, President Barack Obama said states will be allowed to seek a waiver from the law, which requires all students to show proficiency in math and reading by 2014.
Reporting from Rachel Otwell of WUIS used in this report.
Illinois might seek a waiver that would provide relief to schools struggling to meet the requirements of the No Child Left Behind Act.
The federal law was designed to improve achievement and raise test scores. Schools that failed to keep pace with the standards would be penalized. But as the requirements become more rigorous each year, more schools are struggling to hit the mark.
