Protestors are set to gather at a Norwich primary school this morning to mark what they have called the "death of democracy" in the education system.
Cavell Primary School officially becomes an academy today.
It was placed in special measures last year but they soon removed and a recent Ofsted inspection found it was making good progress.
Parents and supporters signed a 2,000-strong petition against the imposition of the academy status, which was led by Norfolk County Council and the Department for Education.
The campaigners are due to hold a minute's silence outside the school at 9am.
The council says academy status is the best option for its long-term improvement.
