Changes by the tests’ maker in recent years have shifted scores upward. That has led to hundreds of thousands of additional students getting what’s considered a passing score – 3 or above on the 1-to-5 scale – on exams in popular courses including AP U.S. History and AP U.S. Government.

The nonprofit behind the tests, College Board, says it updated the scoring by replacing its panel of experts with a large-scale data analysis to better reflect the skills students learn in the courses. Some skeptical teachers, test-prep companies and college administrators see the recent changes as another form of grade inflation, and a way to boost the organization’s business by making AP courses seem more attractive.

“It is hard to argue with the premise of AP, that students who are talented and academically accomplished can get a head start on college,” said Jon Boeckenstedt, the vice provost of enrollment at Oregon State University. “But I think it’s a business move.” The number of students cheering their higher AP scores could rise again next year. The College Board said it is still recalibrating several other subjects, including its most popular course, AP English Language, which attracts more than half a million test takers.
