Burbank school officials say a third-grade teacher has been put on leave after a student reported a got help with answers on state standardized tests.

The Los Angeles Times reported Sunday that Burbank Unified Superintendent Jan Britz announced the investigation at a board meeting last week.

Britz says the student told the principal at McKinley Elementary that students received help with answers on the state's STAR exams.

District' officials investigated and gave their findings to the California Department of Education, which is now conducting its own investigation. The department declined comment.

Britz says it's likely that at least the class's set of tests will be declared invalid, and the school could lose its Academic Performance Index score, which at 835 is well above the state target of 800.
