Having begun in March, the independent report was to be completed and handed down by this week.

But, independent reviewers Geoff Pellizzer and Bob Aston, who are both retired executives of the NSW Department of Education, have encountered issues since restrictions on travel and gatherings were mandated.

The Catholic Diocese of Wagga Wagga has now offered a revised timeline that would see the report completed by the week commencing May 25.

At which time, the recommendations will be delivered to the Archbishop of Canberra Goulburn Reverend Christopher Prowse and the school council.

"The reviewers will be in contact with a number of community and staff members over the next few weeks to finalise the consultation process related to the scope of the review," a spokesperson for the CEDWW said in a statement.

The spokesperson also confirmed that the independent reviewers have continued to consult with stakeholders, access documents, and interview past and present staff members throughout this year.

Parent of a current year 12 student at the school, James Stillman told The Daily Advertiser the delay was understandable but far from ideal.

"The delay in some ways is an advantage and a disadvantage," he said.

"We wouldn't mind a prompt answer, we've been waiting already for a while.

"But we're happy to wait and let it take its cause if we get the right decision in the end."

What would constitute the "right decision", Mr Stillman said was a matter for the school community to decide upon eventual release of the review report.

"I'm really not sure what will come of it all," he said.

"There's a lot of hope among the parents that the principal will be back in 2021, but we are playing a waiting game now."

After five years in the position, principal Rod Whelan unceremoniously resigned from the school in August 2019.

It prompted an enormous reaction from students and parents that led to a preliminary review into systems and culture at the CEDWW.

Since the COVID-19 situation began impacting in early March, Mr Stillman said it has been hard to keep the community focused on the need for the review.

"It feels like the heat has gone out of all of this since the [coronavirus] disruptions this year," he said.

"The virus is upsetting schooling enormously but the situation [at Kildare] has been disrupted since the principal left. We [parents] have been keeping in contact, supporting each other but that isn't easy right now."

Despite the delay, Mr Stillman expressed confidence in the independent review.

"We've already seen some positives coming out of it," he said.

"It sounds like it might have been well overdue. Every institution needs a good shake up sometimes."
