State universities are backing President Barack Obama’s proposed scorecard for US colleges in the hope it will steer more federal aid to them and away from underperforming for-profit institutions.

“Student aid won’t be around in 10 years if we don’t do something to distinguish the good guys from bad guys,” said King Alexander, president of Louisiana State University in Baton Rouge. While a cross-section of college presidents have voiced opposition to the concept, leaders of some public schools are emerging as advocates. They say the measure will showcase the value they offer while stemming the distribution of federal loans and grants to so-called diploma mills that saddle students with debt and poor job prospects.

The Education Department is preparing to release a draft ratings plan this year and a final version next year that could bolster better-performing public colleges that charge less than their private counterparts. Federal officials say the scorecard will emphasize access, affordability and graduation rates, in contrast to rankings such as those from US News & World Report that focus more on an institution’s selectivity and wealth.

More than half of the 50 states have already adopted or are exploring tying higher-education funding to similar performance benchmarks, rather than distributing aid based on enrollment, according to the National Conference of State Legislatures.

“They are more accustomed to having to demonstrate return on investment and are getting in front of the debate and shaping what measures will be used,” said Pauline Abernathy, a vice president at the Institute for College Access and Success, or TICAS, an Oakland, California-based advocacy group.

Underlying the support is a sense of urgency as state backing for higher education shrinks and for-profit schools take a larger slice of federal money. While for-profit colleges enroll 13 percent of students, they account for about a fifth of federal loans and almost half of student-loan defaults, according to TICAS.

Last year, Obama proposed tying college ratings to the distribution of federal student aid, punishing schools that get poor grades, a step that would require congressional approval.

“They’re already losing under the current system, and they can only win under a reasonable rating system,” Mark Schneider, a vice president at the American Institutes for Research and a consultant for Money magazine’s college rankings, said regarding the state schools.

Support for the plan has cropped up at a number of public universities. Nancy Zimpher, chancellor of the State University of New York, one of the largest public systems with 64 campuses, wrote in an online opinion for the New York Times in May that “there is great value in a ranking tool.” William ‘Brit’ Kirwan, the University of Maryland system’s chancellor, said a new rating system is “very needed.”

There is also support among some lawmakers, particularly Senate Democrats who have been focusing on legislation aimed at relieving student debt. In February the Association of Public and Land Grant Universities proposed an alternative plan that included tightening the existing federal student-aid eligibility process to weed out abuse.
