This tool hides the complexity of the process.
Like I said, I once was tasked to write an admissions calculator. This was in 2006, and was for the (at the time) member schools of the Big 12 Conference:
* Texas, Texas Tech and Texas A&M looked only at class rank, with automatic admission to the top 10 percent.
* But Baylor looked only at SAT or ACT score.
* Nebraska would admit based on a flat minimum in any of class rank, ACT score or SAT score.
* Colorado had a flat minimum to satisfy in any of class rank, ACT score, SAT score or GPA.
* Kansas and Kansas State could look at either SAT score or ACT score, or a combination of GPA and class rank.
* Oklahoma and Oklahoma State would use either a combination of GPA and class rank, or an ACT score plus a GPA and class rank, or an SAT score plus a GPA and class rank.
* Iowa State University had automatic admission based on any of six possible combinations of class rank, GPA, SAT score and ACT score.
* The University of Missouri had eight possible combinations.
Assembling the calculator for that required getting information from each of the 12 universities regarding their official admissions standards.
This site tries to calculate automatic scholarship awards based on unofficial sources. Please forgive me if I have concerns over whether the data they have is correct or they've been able to capture the full range of possible options (or whether there really are consistent automatic scholarship-award tiers in the first place).
