INSIDE HIGHER ED. JULY 22, 2013. The College Board and the Educational Testing Service have invalidated Advanced Placement scores at Mills High School, in California, saying that “seating irregularities” may have resulted in some students gaining an advantage on the test, The Bay Area News Group reported. The College Board and ETS aren’t asserting that cheating took place, but that seating for the AP tests did not follow the rules and could have permitted cheating. The AP tests are being rescheduled. Students say that they are all being punished unfairly and that it will be difficult to score as well after their courses have ended. Students have created a website, Why We Need Our Scores Back, about their concerns.
