A Boston University lecturer resigned after using Craigslist to hire someone to help grade student papers, BU officials said.

A BU spokesman confirmed Duane Lefevre, a marketing instructor at the BU School of Management, resigned. The university’s student newspaper, citing an email from the dean of the School of Management, reported that Lefevre acknowledged that he had posted the Craigslist ad and hired someone to help grade papers.

CommonWealth first reported on Lefevre’s help-wanted ad on the Boston section of Craigslist on Nov. 30. The ad offered $15 a paper plus a $50 bonus for “superior work.”

The student papers, according to the Nov. 14 ad, would focus on the profitability of six companies in an assigned industry. “Verify the data is accurate based on the attachments to the paper, assess the accuracy of the analysis, note if there are more suitable ways to asses profitability for that particular industry, assess the quality and flow of the writing, assess the look and feel of the document, provide 10-15 bulleted points of feedback per paper,” the ad said.

An inquiry to the email address listed in the ad prompted a response from Lefevre, who said the job had already been filled.

Contacted by phone at the time through his BU office, Lefevre said the ad was an attempt to speed up the grading process in a course he was teaching. “It’s a busy time for me and I did it to save time,” he said. He later emailed to say he had canceled the job and planned to review the papers entirely by himself.
