A troubled Hull high school has been told by government inspectors that it is failing to provide a satisfactory standard of education.
The new school was the first to be opened in Hull for 20 years
Endeavour School was found by Ofsted to have unsatisfactory staffing levels, low attendance and low standards.
The report says recruiting and retaining teachers is a major problem.
During the inspection in March, Endeavour brought in teachers from other schools and sent disruptive pupils to a local college.
Earlier in the spring term, the head teacher, David Thorp, resigned.
Kevin Beaton, the head of Kingswood High School in Hull, was appointed to take temporary charge of Endeavour.
He told BBC Look North that the Ofsted report came as no surprise.
"I think the key thing is that it has clearly highlighted what we do in the future," he said.
"We have already set in train some plans that will help the school become the school the people of the area deserve."
Two schools were merged in 2001 to create Endeavour which moved into a new £15m building in Beverley Road last September.
In 2003, only 17% of pupils got five good GCSEs or equivalents and the year before only 11% did.
The truancy rate is four times the national average.
Mr Beaton said he was confident school would come out of special measures by 2006 and 16 new members of staff were due to start in September this year.
