The ministry has released the names of these institutions, including universities, foreign language centres and specialised training schools.
They are: College of Business Administration and Management (CBAM); the Hanoi Open University; FTMS Training Co Ltd; Hoa Sen University; Institute of Finance and Administration (IFA); Melior Business School Viet Nam Co Ltd; and Singapore Informatics and Business Management Education Company Ltd (SIBME).
The HCM City-based CBAM, SIBME, FTMS and Melior have been conducting degree programmes without licences.
The Ha Noi Open University has been enrolling students for graduate programmes in co-operation with Australian Box Hill Institute of Technology although the co-operative agreement between the two schools has been invalid since late last year.
Hoa Sen University, in collaboration with French Vatel International Hotel and Tourism Management School, is offering bachelor's degree in international hotel management, which has not been licensed by the ministry.
The IFA has been licensed by the HCM City Department of Education and Training to provide English language training, but the institute has enrolled students for a Master's programme in business administration.
Deputy Chief Inspector of the ministry Pham Ngoc Truc said the ministry has required the seven institutions to stop all their illegal activities, including advertising, enrolling and training students in unauthorised programmes.
These schools would be fined for their violations accordingly, he said.
Specifically, the CBAM would face a fine of VND62 million (USD2970), the Hanoi Open University would face VND7.5 million ($360), Hoa Sen University VND32 million ($1,530), Melior and SIBME VND67.5 million ($3,240) and FTMS VND10 million ($480).
In terms of the benefits of students, Truc said the ministry's Educational Quality Examination and Verification division has considered the recognition of degrees granted by the illegal training programmes to assure the benefits of graduates.
However, he said, these degrees might be refused by the ministry in worst situation.
For those studying at these violating units, the ministry has required the schools to refund tuition fees, he said.
About 900 students were reportedly studying at violating units.
The ministry's International Education Development Department is sending a letter to the embassies of relevant countries to inform them of the companies' wrongdoings.
Truc suggested that students should consult the legality of private schools on the ministry's website www.vied.vn in which the names of licensed schools were posted on to avoid unexpected circumstances.
Previously, ERC Institute Viet Nam, Raffles International College and ILA Vietnam were forced to stop training students due to educational violations, affecting hundreds of students.
