A department head at a New York high school has been accused of changing two students' answers on state tests to give them a passing grade.
The Westchester County district attorney says 54-year-old Allison Risoli of Peekskill was arraigned Monday on false-document charges.
A call to Risoli's attorney was not immediately returned.
The district attorney said Risoli altered answer sheets for January exams in history and geography several days after the tests were taken at Peekskill High.
The original answer sheets had already been scanned in and a comparison revealed the alterations.
The district attorney's office had no information on motive.
The case is unrelated to an investigation into seniors' transcripts at Peekskill. The school said in January that several seniors received credit for a course they did not take.
