LAS VEGAS (AP) - Officials from the Nevada Department of Education say they're investigating how a test scores at a Las Vegas elementary skyrocketed from one year to the next.
Department spokeswoman Judy Osgood said the agency is working with the Nevada Attorney General's Office to see what's behind the eyebrow-raising improvement at Kelly Elementary School.
State data show that from 2008 to 2011, the number of 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 this past year.
Clark County School Board Vice President Lorraine Alderman told the Las Vegas Review-Journal it would be sad if things aren't "on the up and up" at the school.
It's not clear how long the investigation will take.
