The SMI rankings are a collaborative publication from CollegeNet and PayScale. The rankings aim to provide a measure of the extent to which colleges provide upward economic mobility to those that attend. The rankings were created in response to the finding in Science magazine which showed that among developed nations, the United States now provides the least economic opportunity and mobility for its citizens. The rankings were also created to combat the rising costs of tuition, much of which is attributed to the efforts of some colleges to increase their own fame and wealth in ways that increase their rank in media periodicals that put an emphasis on such measures. According to the SMI, the top five colleges are Montana Tech, Rowan University, Florida A&M, Cal Poly Pomona, and Cal State Northridge.
