A department chair at George Washington University resigned last month, and the university is investigating allegations that she did not teach some of her classes but gave all of those students As.

Venetia Orcutt, an associate professor and chair of the Department of Physician Assistant Studies, is accused of not teaching two out of three semesters of an evidence-based medicine course during the 2009-10 school year, according to the Associated Press, which first reported the news.

The AP obtained letters that three students wrote to the university’s provost this fall about the incident. The students say they all received “A” grades and were never given a reason why the classes were not taught.

Orcutt did not return a message left at her home on Monday evening.

The GWU School of Medicine and Health Sciences medical school was on probation from its academic accrediting organization from fall 2008 until early 2010 for not complying with a number of standards, including not properly documenting how students interacted with patients. Student debt levels were also among the highest in the country, some students complained of mistreatment, according to a 2009 investigation by the Post.

The Department of Physician Assistant Studies, where Orcutt taught, is not part of the medical school. The medical school never lost its accreditation, but at the time it was the only one of 129 U.S. accredited institutions to be on probation. It was taken off probation in February 2010.

On Wednesday, the university released more information about the incident. Here’s the link to the most recent story: GWU students can keep credits from untaught classes.

UPDATE: This post was updated on Wednesday to reflect that the department of physician assistant studies is a part of the School of Medicine & Health Sciences but not the medical school.
