A final decision on whether to move Oldfield School to a greenbelt site will not be made by the Royal Borough's planning panel this month.
The council's controversial decision to shift the school from Chiltern Road to a field off Bray Road was deferred by its Maidenhead development committee in September.
Members said at the time they would make a decision in November.
But a borough spokeswoman said today that it will not be included on the agenda for the scheduled planning meeting on Wednesday, November 20.
No revised date has been announced.
The council launched the £9m project to meet growing demand for school places but opponents say the proposed build would cause huge traffic issues and should be scrapped because it is on greenbelt and in a flood plain.
The Royal Borough had wanted it built and open for September 2014.
