LAS VEGAS (AP) -- Government officials are taking responsibility for data errors that mistakenly launched a suburban Las Vegas high school nearly to the top of U.S. News and World Report's "Best High Schools" list.

U.S. Department of Education statistician Marilyn Seastrom says one layer of federal fact checking failed and a second layer was skipped when officials reviewed enrollment data for Henderson's Green Valley High School.

Nevada Department of Education official Julian Montoya says the bad numbers originated from the state office. The statistics first reported by the Las Vegas Sun showed Green Valley had 477 students to 111 teachers, an impressive ratio that propelled it to No. 13 in the nation in Tuesday's rankings.

School Principal Jeff Horn said he was honored, but disappointed to see it was based on faulty data.

A first-grader from Nate Mack Elementary School has earned a pizza party for his class and a laptop computer for himself.

Quinton Larry made the best guess of when desert tortoise Mojave Max would emerge from his burrow. The tortoise crawled out at 12:41 p.m. April 17. Quinton guessed he would come out at 12:30 p.m. April 17. That was the closest guess out of the 3,800 students who entered the 13th annual Mojave Max Emergence Contest. The young man found out about his winning guess Thursday.

Quinton and his entire class will get a field trip to the Mojave Max habitat, a pizza party, medals and T-shirts. Quinton will get an outdoor adventure backpack, a digital camera, a year-long pass to federally managed areas and a laptop computer. The winner’s teacher will also get a new laptop computer. They will receive their rewards May 10.

The Henderson campus of Regis University will shut down in August 2013, according to university officials.

Insufficient enrollment over several years is cited as the primary cause for the closure.

The Henderson campus, which has nine staff, one full-time faculty member and 35 affiliate faculty, will continue in operation until Aug. 31, 2013.  There were 169 students enrolled at the Henderson campus in 2011.
