The system for inspecting schools in England is facing a shakeup after the suicide of head teacher Ruth Perry led to calls for reform.
Ofsted will revisit schools graded inadequate over child welfare within three months and there will be an overhaul of its complaints system.
However, Prof Julia Waters, Mrs Perry's sister, said the move was a start but that far bigger changes were needed, and the National Association of Head Teachers' said the system was still fundamentally flawed.
Ofsted chief inspector Amanda Spielman defended the one-word ratings system that Ofsted uses and said it was down to the Government to make any changes to the way ratings work.
Education secretary Gillian Keegan said the changes were 'a really important step'.
From September schools will also be given more detail of what exactly is expected in measures to keep children safe, which include keeping good records and training staff to deal with concerns
Ofsted said it was listening to concerns 'without losing our clear focus on the needs of children and their parents'.
Ms Spielman said one of the changes announced by Ofsted was to change the language of reports so that it wasn't over-focused on the head and senior leaders.
