@parent2noles I’ve seen several schools not fill out that field. It’s not a data element that’s used by US News in it’s rankings (US news is the driver behind the CDS).US News uses test scores, class rank and acceptance rate in it’s “Student selectivity” category.
UT-Austin, for example, also doesn’t include GPA data in the CDS:

https://utexas.app.box.com/v/CDS2016
If I had to guess, it’s not a number UF uses, so it doesn’t want to go through the trouble of figuring it out. In UF’s 2016-2017 CDS they included the middle 50% range (4.2 to 4.5) but still left the average GPA field blank. The middle 50% number is something they calculate and have to share with the State University System of Florida Board of Governors.
