URGENT repair works at Kalianna School Bendigo will likely begin in August, says principal Peter Bush.
The school was allocated $346,379 in state funding for maintenance works last year but repairs are yet to be made.
Two weeks ago parents of children at the school circulated a petition to the state government urging it to start repairs and calling on it to upgrade the school's facilities.
Mr Bush said some classroom doors needed to be replaced, there was a need for new air conditioners and the roofs needed to be repaired, as they had holes in them and leaked when it rained.
A parent whose child attends the school formerly told the Bendigo Advertiser the boys' toilets were broken but Mr Bush said that was not the case.
Mr Bush said parents were frustrated works had not yet started.
"The frustration with parents was that it was a slow process," he said.
"The works we are getting done are urgent and are being met.
"The process of using those funds is well under way."
He said he would like his school to receive further funding to upgrade facilities but, "There are worse schools out there".
"We would love other upgrades but ... every school in Victoria has been assessed through a maintenance process."
Mr Bush's comments were made during a visit to his school by Department of Education and Early Childhood Development regional director Jeanette Nagorcka.
Ms Nagorcka said Kalianna's condition would be assessed by the department to determine whether it needed additional funding.
Mr Bush's comments contrast ones made to the Bendigo Advertiser two weeks ago, when he urged the government to modernise the school.
"You look around and every Bendigo secondary school has been through a re-modernisation program but we appear to have been left out," he said.
