According to investigative documents obtained by USA TODAY, Munoz erased wrong answers and whispered corrections while she was helping non-native English speakers with difficult words. She snapped her fingers in a code students understood to mean they should correct an answer.
While the teacher was out of the room, Munoz warned the students "not to tell anyone, not even your parents, what I did." If they told, she warned, they "would fail fourth grade."
This is high-stakes testing. The standardized tests required by the federal No Child Left Behind law have become one of the most important — and controversial — ways to measure a student's progress, a teacher's competence, a school's success and a state's commitment to education. That can be a heavy load for an assessment built on paper booklets and bubble sheets.
