The opening of the new Cowes Enterprise College has been delayed again.
Originally the college was due to be opened for the start of the September term but delays to building work caused by wet weather put it back to November 6.
However, the college is now expected to open at a date 'not significantly beyond that of November 19'.
Parents have been told their children should report to the existing school at the start of the next half-term.
Chair of governors, Alan Wells said: "It is a great shame we are not able to meet our previously published timeline.
"However it became clear in a meeting of project partners a number of aspects of staff training and development to ensure both the college's safe operation and the appropriate safeguarding of all pupils on the new site require a little more time."
Janet Newton, IW Council deputy director of schools and education services, said: "We fully support the decision of the college governors.
"This is a hugely important move for the college and its students and we agree everything must be in place to enable a smooth transfer.
"If that means there is a further small delay before full and safe occupation of this state of the art facility then so be it.
"Despite a tremendous effort from all concerned it has just not been possible to pull back all the time lost through the unusually wet conditions over the summer."
