The petition, which had gathered nearly 300 signatures by Tuesday afternoon, was started by Catherine Saba. The Sun Chronicle reported Saba graduated from Mansfield High School last year.
"The status of education in the Mansfield Public School System is on the line," the petition reads. "If we want to set a good example for our students and surrounding areas of what Mansfield education is all about, we need a leader who will make the detrimental consequences of plagiarism clear and take no part in it themselves."
The School Committee was scheduled to discuss the controversy Tuesday night during a nonpublic meeting.
