Parents and students at Kildare Catholic College will stage a demonstration on Monday morning, in reaction to the delayed release of a report into the resignation of their principal.
Last August, principal Rod Whelan announced his sudden resignation following a period of personal leave.
An ensuing independent investigation began to look into the circumstances surrounding the resignation.
The report was expected to be handed down to the school community last week.
It is now expected to be released to the school in June, after the review committee "agreed to a delay of the report to the school council to allow it to be considered more fully".
Disappointed with the delay, parent of a year 7 and year 12 student, Paula Gray, told The Daily Advertiser the community has been "patient long enough now".
"We've waited a long time for answers, we're not waiting any longer now," Ms Gray said.
She called the demonstration a "community gathering" to "show solidarity and support for Rod [Whelan], the students and the teachers".
But, Ms Gray said, the intention was not to "repeat history", by re-staging the demonstration that took place at the school in the week following the initial resignation.
"We're showing up for support, this is different, but we're still looking for answers," Ms Gray said.
"This is going to be a COVID-19 appropriate demonstration, with social distancing and everything that needs to be done."
Joining Ms Gray's two children in walking out of their classrooms on Monday will be fellow parent, Frank Goodyer's three children.
Mr Goodyer echoed Ms Gray's call for the Catholic Education Diocese of Wagga Wagga to make public the exact reasons for Mr Whelan's initial resignation.
"In my opinion the church has learnt nothing from the Royal Commission, it's still keeping things secret," Mr Goodyer said.
"I'm appalled by the lack of answers, I'm appalled we're still waiting. Yet I still believe in Catholic education, I believe in it enough to keep sending my kids there.
"The people that are important in my kids' lives are their teachers," Mr Goodyer said.
"The systems that were put in place by Rod Whelan, I support his teaching, his processes and while he was snatched away from us, I'm worried what he's put in place will be removed too."
Mr Goodyer said Monday's demonstration would again call for Mr Whelan to be reinstated as principal of the Wagga school.
"The position is still vacant, it hasn't been advertised. I'm sure he would come back in a heartbeat," Mr Goodyer said.
"Back to the school he loves, to the students who love him. He still has so much to give as their principal."
