Caroline Maria McNeal of Huntingdon is accused of using the passwords of three co-workers without their knowledge to tamper with dozens of grades and test scores between May 2006 and July 2007 at Huntingdon Area High School in central Pennsylvania, the state attorney general's office said.

McNeal, 39, is alleged to have improved her daughter Brittany's grades and reduced those of two classmates to enhance Brittany's standing in the 2008 graduating class.
