China has issued a management regulation for people working at after-school tutoring institutions to better regulate the institutions.

The regulation, jointly issued Tuesday by the Ministry of Education and Ministry of Human Resources and Social Security, said tutors for academic subjects should have teaching credentials, while those for non-academic subjects should have relevant professional qualifications.

No teachers at kindergartens and primary and secondary schools should work at tutoring institutions, the regulation said.

The number of full-time tutors and researchers should account for more than 50 percent of all people employed by the institutions, it said.

Tutoring institution employees should support the Party's leadership and socialism with Chinese characteristics, abide by laws and regulations, and have good morality and professional ethics, the regulation stipulated.

The regulation also included "red lines" for the employees, including violating Party's policies, disseminating wrong information and views in classes or online, engaging in inappropriate relationships with students, discriminating against or abusing students, using drugs or engaging in other criminal activities, it said.

People violating the regulation should be fired by tutoring institutions and those with serious misconduct will be included in the national blacklists for tutors, it added.
