I find it very hard to believe that some schools have a 0% 4-year graduation rate, but here you go; https://www.cbsnews.com/news/25-universities-with-the-worst-graduation-rates/
The two that jump out at me are Texas A&M - Commerce because they run a lot of DL programs from there, and the other is Chicago State U because they've been in the news with financial problems, accreditation problems, etc.
The article kind of tells you why the stats are misleading, but the author still doesn't seem to grasp why. I'm familiar with the Texas schools. A lot of them serve poor students and working adults. As the article said, the government does not track students who enroll part-time their freshman year. That means that students who have to work full-time are not likely to be tracked. Also, part-time students are not going to finish in four years. While bigger and better universities tend to admit students who need no remediation or get transfer students who already received remediation at community colleges, most of the universities on this list admit lower-performing students directly. If they need a semester or two of remediation, then they are not going to finish in four years. I believe there are 6-year graduation rates; that article probably should have included those as a comparison. Sam Houston State University, which the article spelled incorrectly, usually has a graduation rate that is over 50%. The amount of time that is considered reasonable varies by program from three years to six years. This article is very misleading. Most of their students are not leaving without a degree, and they aren't leaving with a ton of debt. These are some of the cheaper colleges.
Ok, so I checked this against the College Completion Database project, and I'm not sure if the original list is old or wrong, but something about that list is fishy. College Completion: Graduation Rates and Data for 3,800 Colleges
You should have read the article and my posts before you shared that article. The article is from 2011. Refer to my post above on why the stats are misleading. The information is old, and the interpretation is wrong.

Problems with this article (and IPEDS in general): Students who attended any prior institution - Not counted Students who attend part-time - Not counted Students who attend full-time (12 credit hours) but do not attend during summers, so they take longer than 4 years - Not counted Students who have to repeat any courses, so they take longer than 4 years - Not counted Students who change their majors, so they take longer than 4 years - Not counted Students who decide to add an extra minor or take some additional courses of interest, so they take longer than 4 years - Not counted I would agree that the listings are misleading.
