Grade inflation in higher education has become an issue in the U.S. over about the last 50 years. One 2017 report proposing solutions to the problem noted that despite the impression that college students have heavy work loads, researchers found that students worked about 10 hours less per week over a period of about 40 years ending in 2004, and they obtained 10% higher grades between 1991 and 2006.
Another ongoing grade inflation review project begun several years ago in connection with an article in the Washington Post, reported that As represented 43% of all letter grades in colleges in 2016, up by 12% since 1988 and 28% since 1966.
