President Barack Obama dearly wanted to get the government in the business of rating colleges and universities based on value and affordability, promising a new system by 2015. Now that goal is shriveling under the weight of a concerted opposition from universities, lawmakers and bureaucrats in Obama’s own administration. Nearly two years after the president, standing before a crowd of 7,000 at the University at Buffalo, unveiled the bold proposal as a way to curb soaring college costs, his administration has quietly but drastically scaled back the initiative. No longer does the federal government intend to use a formula to score schools based on factors like price, average student debt and graduation rates, as Obama had envisioned.
