Police alleged the offending occurred between the 1970s and late 2000s.
All seven men were initially granted name suppression but Alister Harlow, Ian Wilson and Ross Browne, the school's former chaplain of 26 years, lost name suppression last month.
A fourth man also lost name suppression last month but cannot be named yet as his lawyer Claire Farquhar indicated that decision would be appealed.
Dilworth has apologised for the way it previously handled historical allegations but says there are new processes in place and management will support any former student who would like to go to police now.
Headmaster Dan Reddiex, who was appointed last year, said on the day of the arrests the school had zero tolerance for abuse of any kind.
"The health, safety and wellbeing of our students is our single greatest priority and responsibility.
"We know that a safe environment is instrumental to our students flourishing both personally and academically."
