Selwyn House School for boys has completed the settlement process with dozens of students who allege they were abused by their teachers in the 60s, 70s and 80s.

In a letter to the school community, it said the process is now complete and it issued an apology as well.

"The Association has expressed its sincere and deepest apologies to the student claimants and their families, and it hopes that the settlement will help them and their families heal and move on with their lives," the apology said.

The apology is part of the settlement process. In 2005 former students launched a class action suit against the school alleging they were sexually abused at the school by teachers.

Last year the school offered $5 million to settle the issue. More than 30 students who submitted claims have been paid, however their lawyer says the full $5 million has not been used.

One former student said the apology will allow him to move on, but that he is not completely satisfied with the way they said it.

"We expected them to admit that mistakes were made and students were let down," he said. "There are dozens of men that have come forward. The money doesn't buy back their innocence. The one thing we need, they still hold back from us."
