Iran's education department has banned "ugly" teachers from the classroom, including women with facial hair or those suffering from acne.
A list of proscribed ailments, including having a scar or a fungal infection was released by the FARS news agency.
Anyone who is cross-eyed, has ugly facial moles or skin conditions such as acne or eczema faces redundancy, according to Mail Online.
Women who have facial hair will also be sacked, along with teachers with fewer than 20 teeth or those suffering a fungal infection.
Women are allowed to teach in Iran although they must wear a scarf covering their hair.
Art teachers will be sacked if they report they are colourblind and infertile female teachers will also be banned from the classroom.
Twitter users have citicised the rules, claiming if implemented in full, people such as Stephen Hawking would be prevented from teaching students in Iran.
An adviser to the Iran's president has since promised that the list would be investigated.
As a result of the backlash, an education spokesperson told the Tehran-based Etemad newspaper that rules specifically targeting women would be removed and the rest of the list reviewed, according to Euro News.
