Another educational institution has put Imee Marcos' credentials in question, after acknowledging that the program Marcos placed in a published curriculum vitae did not exist.

While the Asian Institute of Management (AIM) refused to provide information on whether the senatorial candidate was enrolled or had graduated from their school, it was certain that an MA MBA had not been offered.

“In our 50 years of providing world class programs we never offered an MA MBA,” Registrar and Student Experience Director Bryan Magbutay told ABS-CBN News in an email, responding to a query about Marcos’ claim that she received an “MA Management and Business Administration” from the institution.

“I’m not at liberty to provide any other answer except for the one already provided,” Magbutay added in a follow-up email.

Instead of a Master of Arts in Management and Business Administration, AIM has offered the following programs although some have been discontinued or renamed: Master in Business Management, Master in Business Administration, Master in Management, Executive Master in Business Administration, Master in Development Management, Master in Entrepreneurship, Master of Science in Innovation and Business and Master of Science in Data Science.

It was unclear if Marcos or her staff made a mistake when listing down her degree for her curriculum vitae, which was previously posted on the Congress website.

ABS-CBN has reached out to the Marcos camp but has yet to receive any reply as of posting.

Marcos’ status as a student at various universities has been the subject of debates since she filed for candidacy in October last year.

Inconsistencies in educational attainment

Earlier, the prestigious Princeton University reportedly denied that the senatorial candidate graduated from their university although she was enrolled in 1973. This puts into question why the then congresswoman of Ilocos Norte wrote in her curriculum vitae “Princeton University” and “with honors.”

And while Marcos posted a photo of her allegedly graduating from the University of the Philippines College of Law, the state university stated that she only took courses and did not graduate from UP. This would make it impossible for her to receive the distinction of “cum laude,” which was stated in the same CV.

Furthermore, a 1986 book written by the late UP law dean Froilan Bacungan recalls how Marcos was part of a PR stunt to make it seem that she graduated. At that time, her father, the late dictator Ferdinand Marcos, was the president of the Philippines.

Writer Raissa Robles also posted a copy of the UP College of Law yearbook, which did not include Marcos.

Opposition candidates have since mocked Marcos for her alleged “fake degrees.”

While critics questions Marcos’ honesty and integrity because of the supposed false information written in her CV, her ally, Davao City Mayor Sara Duterte-Carpio has defended her. Duterte-Carpio said all candidates have lied so honesty should not be an issue.
