In September 2021, El Financiero reported on a review by the Auditoría Superior de la Federación, the federal audit office.
It had found “dudas en la autenticidad de 305 mil 333 títulos y 29 mil 588 cédulas profesionales” (doubts about the authenticity of 305,333 titles and 29,588 professional licenses) registered by the Ministry of Public Education. The ministry replied that the universities issue the degrees, and that the audit did not affect the authenticity of the licenses.
