The percentage of A's given out in colleges and universities almost tripled between 1940 and 2008, and A's made up almost 45 percent of grades given out in 2008. The percentage of B's has dropped slightly after a peak during the 1970s and '80s, and the percentage of C's dropped sharply after 1966 and again from the late 1980s to 2008, to about 15 percent in 2008. D's and F's have dropped to less than 5 percent each after starting at about 12 percent and about 6 percent, respectively. Researchers attribute the sharp rise in grades to historical factors, such as a reluctance for professors to fail students during the Vietnam War, as well as a more consumer-based approach to education.
More facts about universities and grade inflation:
- Private universities tend to inflate grades the most, with A's and B's accounting for about 86 percent of all grades in private universities per year, as opposed to about 73 percent in public universities.
- Researchers believe that the increase in grades was probably not because of harder working students. Rather, they believe that higher grades actually contribute to less student engagement, because if the students are expecting A's, they are not likely to make as much effort.
- The types of schools that grade the harshest are those in the Southern U.S. and those that focus on engineering or science. Liberal arts schools tend to grade the easiest.
