Three panhandle schools have been cleared by the Texas Education Agency of allegations of TAKS cheating.
Amarillo High, Crocket Middle and Sanford-Fritch Elementary schools are no longer suspected of cheating on the TAKS test.
Those campuses along with Muleshoe High School were flagged by the agency because of unusual scores on the 2005 exam.
An independent task force was appointed to conduct on-site interviews at each of the schools to determine if teachers helped students cheat.
At this time Muleshoe is the only school in the panhandle that remains under investigation.
In all, 700 schools were found with irregularities in 2005. Today a total of 592 schools across the state were cleared of wrongdoing.
