High school students in Denmark will be required to verbally defend their written assignments as part of emergency government measures aimed at combating AI cheating.

A verbal defense will be needed for all exams written at home, Denmark’s Ministry of Education announced in a statement Thursday, adding that it will work with schools to create the best framework for this.

The rule, which comes into force immediately, applies to students in upper secondary education, which typically begins around age 16. It will include the approximately 9,000 students enrolled in the country’s two-year Higher Preparatory Examination program, who have to submit major written assignments each year, according to the ministry.

The ministry is also calling on high schools to use tools to monitor students’ screens during exams, as well as a firewall to filter the content they can access during exams and in class.

In addition, it is encouraging schools to get students to complete more assignments in school, under controlled environments, to make supervision easier.
