SEATTLE, Wash. -

A Seattle elementary school is under review after a big jump in the school's state test results.

The Seattle Times reports Beacon Hill International School saw such big increases in math and reading scores that the school district asked the state to take another look at the school's scores.

The district said it discovered the spike while reviewing preliminary data earlier this month.

A spokesman for the state Office of the Superintendent of Public Instruction says it was the only such anomaly reported by any district in the state this year. Nathan Olson says the review should take a few weeks.

He says state officials are trying to find out if there's an innocent explanation for the anomalies.
