Ok so lets look at the list of public universities with a higher percentage of IS students when compared to CU:
Central Michigan, Cooper Medical School of Rowan, East Tennessee State, Florida Atlantic University, Florida International University, Florida State University, Indiana University School of Medicine, University of Buffalo, LSU New Orleans, LSU Shreveport, McGovern, Medical College of Georgia, Medical University of South Carolina, Michigan State, Northeast Ohio, OHSU, Rutgers NJ, Robert Wood, Sanford South Dakota, Southern Illinois, SUNY Downstate, SUNY Upstate, Stony Brook, Texas A&M, Texas Tech, Texas Tech Lubbock, Brody East Carolina, San Antonio, Toledo, University of Alabama, University of Arizona, University of Arizona Phoenix, University of Arkansas, UC Davis, UC Irvine, UCLA, UC Riverside, UCSD, UCSF, University of Connecticut, University of Florida, University of Hawaii, University of Illinois, University of Iowa, University of Kansas, University of Kentucky, University of Louisville, University of Maryland, UMASS, University of Minnesota, University of Mississippi, University of Missouri Colombia, University of Nebraska, University of Nevada, University of New Mexico, University of North Carolina, University of Oklahoma, University of South Alabama, University of South Carolina, University of Texas medical branch, UT Southwestern, University of Utah, University of Wisconsin, Wayne State, Wright State.
Yes, as you pointed out, some of these schools do have a greater margin of difference between the percentages of OOS matriculants (example CU 34% OOS, Utah 25% OOS, LSU Shreveport 1% OOS). Still, do you notice a trend here?
OK, now out of that list, lets look at the list of schools that receive EVEN LESS in-state applications than does CU (yet the class is STILL composed of a higher percentage of IS students):
Medical University of South Carolina, Sanford South Dakota, University of Kentucky, University of Mississippi, University of Nebraska, University of Nevada, University of New Mexico, University of Oklahoma, University of South Alabama, University of South Carolina, University of Utah.
Do I disagree with the University of Washington as well? Absolutely!
