SANDOWN Bay Academy has been placed into special measures by Ofsted.
Parents were informed by letter this morning (Saturday) that the Isle of Wight school has been judged by the schools watchdog not to be providing an acceptable standard of education.
The special measures status comes into effect from Monday and parents and carers have been called to two meetings about the decision, to be held on Tuesday, March 12.
Sandown follows Cowes Enterprise College into special measures.
The letter, from chair of governors John Gansler, was also signed by Jonathan De Sausmarez, AET's regional director of education.
AET is the national educational trust which runs Sandown and Ryde academies, following 2011's schools reorganisation.
The letter states there were 'no excuses' for the unacceptable standards of achievement, behaviour and leadership Ofsted has found.
It goes on to say the school is bitterly disappointed at the findings.
Officials recognised interim headteacher Shaheen Khan-Jones, formerly at Carisbrooke College and who took over at Sandown last year, had set up new systems to ensure rapid improvement but these had not yet taken full effect.
The letter also states the school will now have access to additional resources and support as it is in special measures.
One parent, who did not wish to be named, told the County Press the findings were deeply worrying for her children and everybody else involved.
She said: "My children say there is little continuity of teaching and that cannot be good for them.
"I tried to move one of my children to Christ the King College in Newport but that is full.
"You have to think this has a lot to do with the reorganisation and I question whether that was done properly."
The meetings on March 12 are from 5pm to 6.30pm for parents of younger children and 6.30pm to 8pm for older age groups.
The full findings of the Ofsted inspection, which took place on January 16 and 17, will be on the Ofsted and school websites from Monday, according to the letter.
