After more than 10% of law schools announced they will no longer participate in the U.S. News & World Report education rankings, the news agency sent a letter to law deans Monday informing them of methodology changes, but at least one dean is calling the move "too little, too late."

U.S. News reported that following conversations with more than 100 deans, that it will be "making a series of modifications in this year's rankings that reflect those inputs and allow us to publish the best available data," Robert Morse, chief data strategist, and Stephanie Salmon, senior vice president of Data & Information Strategy, said in the letter.

Megan Carpenter, dean of the University of New Hampshire, Franklin Pierce School of Law, told Law.com Tuesday, "The announcement from U.S. News about its intended modifications is too little, too late, and too vague."
