Wyoming is one of the most sparsely populated states in the country, so it is no surprise that there are very few colleges and universities in this state. However, Wyoming residents have a strong public institution in the University of Wyoming as well as several community colleges and tribal colleges. Until 2006, unaccredited private colleges flocked to Wyoming, and diploma mills became a real concern in the state. But Wyoming passed a law that requires all degree-granting institutions to be accredited, which forced these operations to earn their accreditation or move out of Wyoming. The legislation has been very effective at resolving the issue of accreditation in Wyoming’s already limited higher education options.
