Utah's largest school district has agreed there will not be prayers during 1991 commencement ceremonies at two high schools.

The decision Tuesday came one day before a court hearing in the case. The judge may rule on whether other Utah high school students can include prayer in this year's graduation exercises, most of which are just two weeks away.Granite School District reached an agreement with the American Civil Liberties Union affirming it would not "knowingly allow students to recite prayer" during upcoming graduations at Granite and Olympus high schools.

In return, the ACLU will drop the district from a motion for preliminary injunction scheduled to be argued Wednesday before U.S. District Judge J. Thomas Greene, said Utah ACLU director Michele Parish.

The motion remains pending against Alpine School District.
