Kid reporters learn the darnedest things.

That’s a lesson one former principal in Kansas has learned after student reporters dug into her past, ultimately raising questions about her credentials to serve as Pittsburg High School’s top administrator and her $93,000 salary.

“She was going to be the head of our school, and we wanted to be assured that she was qualified and had the proper credentials,” Trina Paul, an editor of the Booster Redux, the school’s newspaper, told the Kansas City Star. “We stumbled on some things that most might not consider legitimate credentials.”

The students began delving into Amy Robertson’s background after an online search of her name produced several stories published by Gulf News about an English-language school connected to Robertson in Dubai, where she has lived on and off for the past two decades, according to Maddie Baden, a 17-year-old junior at the school.

The articles from 2012 said Dubai officials had suspended the license of the school where Robertson worked and accused her of not being authorized to work there as principal. The private, for-profit school got an “unsatisfactory” rating before being shut down in 2013.

“That raised a red flag,” Baden told the newspaper. “If students could uncover this, I want to know why the adults couldn’t find this.”

Baden had initially interviewed Robertson to “introduce the new principal to the community” before learning about her background. On Friday, the students questioned the legitimacy of Corllins University, an unaccredited, online school where Robertson said she received her master’s degree and doctorate after earning her bachelor’s degree at the University of Tulsa.

Officials from the US Department of Education later confirmed the students’ report that Corllins University is not accredited by the agency and the school wasn’t included among its list of institutions closed since 1986, the Star reports.

Faced with the mounting controversy, Robertson resigned Tuesday following a closed meeting that day at the Pittsburg Community Schools Board of Education.

“In light of the issues that arose, Dr. Robertson felt it was in the best interest of the district to resign her position,” Superintendent Destry Brown said in a statement. “The Board has agreed to accept her resignation.”

For her part, Robertson told the Kansas City Star in an email that the current status of Corllins University is “not relevant” because there was no issue at the time she earned her degrees. Officials from the Council for Higher Education Accreditation told the Star that the school could have been accredited in the past.

“All three of my degrees have been authenticated by the US government,” wrote Robertson, who declined to address the credential allegations directly.

“I have no comment in response to the questions posed by PHS students regarding my credentials because their concerns are not based on facts,” she wrote the newspaper.

The school’s journalism adviser, meanwhile, said she was proud of her budding scribes.

“They were not out to get anyone to resign or to get anyone fired,” Emily Smith said. “They worked very hard to uncover the truth.”
