The Texas A&M Grade History Database is a tool to visualize the history of grades for any given course at Texas A&M. The program was originally produced and maintained by Jon Janzen and the majority of the backend code can still be attributed to him. I took over the project when he graduated from Texas A&M in December 2019.
The Office of the Registrar produces spreadsheets that list information about past year's course grade distributions. This tool collects information from these documents and compiles them into a readable and useful format. The oldest records available extend back to 2016 and new data are typically made available by the Office of the Registrar within 4 months of the conclusion of a semester.
