State education officials have launched an investigation into one of New Mexico's top performing public high schools over allegations of testing "irregularities."
Officials from the state's Public Education Department visited La Cueva High School in Albuquerque on Thursday to question students and teachers over the Standard Based Assessments that students took last month.
The required exam helps determine schools' grades under the federal No Child Left Behind law.
La Cueva Principal Todd Resch told teachers in a letter that the interpretation of a "personal break" prompted the audit.
Students aren't supposed to even use the restroom without an escort.
Albuquerque Public Schools says the investigation doesn't involve any seniors, but district officials wouldn't say if the issues involve any students accused of cheating.
