An incoming Kansas high school principal has resigned after student reporters raised questions about her credentials.

School board members voted Tuesday to accept Amy Robertson’s resignation as Pittsburg High School’s principal.

The main concern stemmed from her receiving her masters and doctoral degrees from Corlinns University, an unaccredited, online school. Robertson said she received her degree before the university lost accreditation.

Superintendent Destry Brown says the district will probably be making changes to its vetting process. He also praised reporters with the student newspaper, “The Booster Redux,” saying “our kids ask questions and don’t just accept something because somebody told them.”

An anonymously circulated letter also raised questions about Robertson’s qualifications. Robertson is currently working in Dubai in the United Arab Emirates.]
