Gwent Tertiary College management posts were cut from 120, with 47 returning from summer holiday as full-time teachers. They took posts made vacant from natural wastage, voluntary redundancy and early retirement.
John Hamilton, the acting principal, said reorganisation would not damage the number and quality of teaching staff.
The college is still refusing to publish reports by former Swansea principal Cyril Lewis and accountants Ernst and Young on its management. But the Further Education Funding Council for Wales and the National Audit Office will carry out reviews this autumn, "when all relevant data will be published", said Mr Hamilton.
* At Southwark College, in South-east London, two NATFHE negotiators claim they have been made redundant because of their union roles. Dave Jenkins, a careers teacher, and Andrea Keneally, who have both been at Southwark for 15 years, will appeal against their redundancy next week.
