The NSW Government has been accused of wasting millions on a faulty TAFE IT system.

From 2009, the NSW Government began implementing its Learning Management and Business Reform (LMBR) network, which was rolled out in TAFE campuses over four years.

Despite a price tag of over $500 million, the system has seen major problems, including failing to send out students’ results and causing what staff describe as “disastrous” problems.

The state’s Opposition has long called for the NSW Government to be held accountable, and it appears to be getting through.

After defending it for several years, NSW Skills Minister John Barilaro has now admitted that the system is not working.

“We continue to experience IT system issues across the TAFE network,” he said.

“It's causing problems for our admin staff as they deal with enrolments in this peak period, and more importantly making it hard for them to link enrolments to revenue.”

But the system will not be scrapped, Mr Barilaro said, instead pledging to address the issues this year.

“Over the past 12 months we've put in place a number of modifications that have eased some of the pressures we saw in 2015,” the Minister said.

“We are reviewing the system, as we are reviewing the whole of TAFE.”

Opposition education spokesperson Chris Minns said millions had been wasted before the Government admitted the system was broken.

“They have repeatedly dodged questions about how much money they have wasted on this important system,” he said.

“It's eight years late, it's close to a billion dollars over budget, it's only in one in 10 schools.”

Mr Barilaro said it was a heavy-handed review.

“The system hasn't cost 500 million plus for TAFE - the portion for TAFE is in tens of millions, and it's an investment,” he said.

“There are many parts that are working, but what hasn't happened is one IT system for schools and TAFE that isn't working well, and that's what I'm looking to fix.”
