NEWPORT BEACH, Calif.—Several Orange County high school students are accused of hacking into computers to change grades and access tests.

School administrators tell KABC-TV ( http://bit.ly/1beIJ8l) they are aware of about a dozen students at Corona del Mar High School allegedly involved in the hacking scandal, but more may be implicated.

Officials say they learned about the alleged cheating via a tip from someone on the Newport Beach campus.

Newport-Mesa Unified School District spokeswoman Laura Boss says the district is cooperating with police.

KABC says investigators are looking into allegations that the students may have gotten help from a private tutor.
