Sir John Talbot School in Whitchurch put in special measures
A Shropshire secondary school has been put in special measures after inspectors found it inadequate.
Ofsted was highly critical of the Sir John Talbot School in Whitchurch, highlighting widespread underachievement in English and Maths GCSEs.
The head teacher Malcolm Roddy resigned last week, ahead of the report.
Shropshire Council said it had replaced the governing body in December with an interim executive board.
It said the decision had been taken after council officers became concerned over falling standards.
Ofsted's report said school leaders were now focused on improving the school, but some of them had not been in place long enough to influence standards.
There was some praise for the school's art department, where attainment is above the national average.
The report stated, however: "The overall quality of teaching is inadequate because it has not brought about any improvement in achievement in recent years.
"Although good teaching was evident in a majority of lessons observed during the inspection, the quality of teaching is improving too slowly."
Kate Campion, chair of the new school board, said while she was disappointed by the report, she was "not surprised".
She said the new board hoped to make "significant changes quite quickly".
Sarah Longville, head teacher at The Marches School in Oswestry, will temporarily oversee the school, the local authority said.
The school will now receive monitoring visits every few months before the next full inspection.
