The Ofsted report into Woodlands School in Aspley, Nottingham, also says the school was failing to give its pupils an "acceptable standard of education."
The report also says the school's ability to improve was "uncertain" because some senior staff did not understand safeguarding and positive behaviour approaches well enough and did not demonstrate high enough expectations of pupils' progress.
However, they did note that ways of improving teaching led by the executive headteacher had been successful so that no teaching was inadequate.
It [Woodlands School] is failing to give its pupils an acceptable standard of education and the persons responsible for leading, managing or governing the school are not demonstrating the capacity to secure the necessary improvement in the school.
