DURANT, Iowa (AP) -

An eastern Iowa school principal has agreed to step down as part of an $850,000 settlement from an ethics inquiry.

Davenport television station KWQC reports Monica Rouse voluntarily stepped down Monday. Her attorney says the money is in addition to $300,000 the Durant Community School District has already given her in back pay from the ethics inquiry.

The settlement ends years of litigation between Rouse and the school district that stems from her firing at Durant High School in 2009. Administrators alleged Rouse changed records to allow some students to graduate. She took her termination to court and was reinstated as principal.

Rouse claimed she was mistreated when she returned and the district school board was found in contempt.
