It’s simple. Announce the Spring kids’ stats as a separate item or at least include them in the total admit profile for that year’s class. There is a reason they omit the data from that class.
If the spring numbers helped the college in higher GPA and test scores you would immediately see them show up in the class profile.
The common data set is 34 pages long, they even include transfer applicant information, but there is no mention of the 100’s of Spring enrolled students. Very odd…almost like they don’t even exist.
