A group of high-school students and parents in Orange County, California, are protesting the cancellation of the students’ Advanced Placement test scores due to allegations of cheating and mismanagement, the Los Angeles Times reported today.

The scores of 385 students at Trabuco Hills High School were nullified.

Some proctors were seen sleeping, reading, or leaving the room during the exams, students have said. Ten students later admitted that they had cheated on two of the tests using text messages. Students are not allowed to use cellphones during the exams.

The group, which calls itself Justice for 375, is pressuring the College Board and the Educational Testing Service to reinstate the other students’ scores.

The Educational Testing Service, which administers AP exams for the College Board, has refused to consider letting the students use their original scores. A spokesman for the service told the Times that if the only problem had been cheating, the innocent students’ scores could have been used, but irregularities at the testing site made that impossible.

The students will be given an opportunity to retake the tests on August 11. Both students and parents have complained that retaking the exams will be difficult, as students will have to get their textbooks back and may have time conflicts with the new test date. —Beckie Supiano
