WASHINGTON (AP) — The Trump administration is rescinding Obama-era guidance that encouraged schools to take a student's race into account to encourage diversity in admissions, a U.S. official said Tuesday.

The shift would give schools and universities the federal government's blessing to take a race-neutral approach to the students they consider for admission. Such guidance does not have the force of law, but schools could use it to help defend themselves against lawsuits over their admission policies.

The action comes amid Supreme Court turnover expected to produce a more critical eye toward schools' affirmative action policies.

The high court's most recent significant ruling on the subject bolstered colleges' use of race among many factors in the college admission process. But the opinion's author, Anthony Kennedy, announced his resignation last week, giving President Donald Trump a chance to replace him with a justice who will be more reliably skeptical of affirmative action.

A formal announcement was expected later Tuesday from the Justice and Education departments, according to the official, who spoke on condition of anonymity because the official was not authorized to speak on the record.

The guidance from the Obama administration gave schools a framework for "considering race to further the compelling interests in achieving diversity and avoiding racial isolation."

In a 2011 policy document, the administration said schools have a "compelling interest" in ensuring a diverse student body, and that while race should not be the primary factor in an admission decision, schools could lawfully consider it in the interest of achieving diversity.

"Institutions are not required to implement race-neutral approaches if, in their judgment, the approaches would be unworkable," the guidance said. "In some cases, race-neutral approaches will be unworkable because they will be ineffective to achieve the diversity the institution seeks."

The administration issued a similar guidance document in 2016 aimed at giving schools a framework for "considering race to further the compelling interests in achieving diversity and avoiding racial isolation."

The Obama approach replaced Bush-era policy from a decade earlier that discouraged affirmative action programs and instead encouraged the use of race-neutral alternatives, like percentage plans and economic diversity programs.

The Trump administration signaled Tuesday that it planned to reinstate the Bush administration's philosophy.

Civil liberties groups immediately decried the move, saying it went against decades of court rulings that permit colleges and universities to take race into account.

"We condemn the Department of Education's politically motivated attack on affirmative action and deliberate attempt to discourage colleges and universities from pursuing racial diversity at our nation's colleges and universities," Kristen Clarke, president and executive director of the Lawyers' Committee for Civil Rights Under Law, said in a statement.

In 2016, the Supreme Court, in an opinion written by Kennedy, granted affirmative action policies a narrow victory by permitting race to be among the factors considered in the college admission process.

Kennedy wrote that the University of Texas' admission plan was in line with past court decisions that allowed for the consideration of race to promote diversity on college campuses.

The ruling bitterly disappointed conservatives who thought that Kennedy would be part of a Supreme Court majority to outlaw affirmative action in education. Justice Antonin Scalia died after the court heard arguments in the case but before the decision was handed down.

Eight states already prohibit the use of race in public college admissions: Arizona, California, Florida, Michigan, Nebraska, New Hampshire, Oklahoma and Washington.

The Wall Street Journal first reported the move.
