LAS VEGAS (AP) - An investigation by the Nevada Department of Education has determined standardized test answer sheets at a Las Vegas elementary school were altered by adults and led to skyrocketing scores from one year to the next.
The department issued a statement Wednesday saying the 2011-2012 test scores at Kelly Elementary School will be invalidated, and the findings will be forwarded to the Clark County School Board for possible disciplinary action.
The Nevada Attorney General's office and the department started investigating after the school submitted scores showing eyebrow-raising improvement.
State data show that from 2008 to 2011, the number of Kelly Elementary fifth-graders considered proficient in reading never reached 25 percent. But that figure leaped to nearly 78 percent for the 2011-2012 school year, and hovered at 72 percent in 2012-2013.
