A highly critical report that the Correspondence School tried to keep secret says there were major short-comings in the school's introduction of a new computer system last year.
The independent report has reviewed the move to a $12 million student management system, which was dogged by problems.
The report is critical of the way the project was governed and managed and says there was consistently poor decision-making and a sense of false optimism.
The Correspondence School says the report was a draft and the board did not accept it or a second version provided in October.
