Virtually all of the board agreed to stand down following Mr Ward's January departure over improper links with suppliers including a pound;650-a-month consultancy deal.
They agreed to go - once the new board was in place - following The TES investigation into the Ward affair and subsequent opposition voiced by 70 per cent of AOC members at a heated meeting in Birmingham last month.
Moves to replace the board were agreed at an AOC corporation meeting this week. It is expected that nomination papers will go out next week. Three weeks is required for the return of forms.
AOC chairman Jim Scrimshaw said: "We can expect the process to be finished by early to mid May. It was also agreed at the meeting to suspend the appointment of the new chief executive until the new board is in place."
