Grade inflation at 34 public universities in Texas (2012–2019)

We use 77,420 courses' grade sheets from all 34 Texas public universities for 2012–2019. Significant differences in grades exist across majors. In 2019, economics (29%) and maths (31%) have the lowest percent of A's, while education (nearly 70%) and arts-performance and studio (64%) have the highest percent of A's. A's rose from 42.0% in 2012 to 48.5% in 2019, of which 73.2% of the increase is unexplained, i.e. could be deemed 'grade inflation'. Introductory classes have a lower percentage of A's than non-introductory classes, but both experienced a similar increase in A's.
