Data from the National Centre for Vocational Education and Research, released on Thursday, reveals only 5000 people started training in the 12 months to September 30 last year, down from 5700 at the same time in 2014.

The number of Tasmanians in training at the end of September was 8100, compared with 8800 the previous year.

That figure decreased from 12,200 people in training in 2010.

Nationally, the number of people in training decreased by 13.7 per cent in the 12 months to September.

Franklin Labor MHR Julie Collins said federal cuts of almost $2.5 billion from skills and training and axing critical programs like the National Workforce Development Fund were "starting to cost Tasmanians access to work".

"Following revelations last month that TasTAFE has already expended all its VET Fee Help funding this year because of Federal Government caps, it is becoming almost impossible for young Tasmanians to get the training they need to work," she said.

"We need to ensure that young Tasmanians have the skills they need for the jobs of the future."

Federal Vocational Education and Skills Minister Scott Ryan welcomed the report, saying nationally it showed take-up and completion in traditional trade apprenticeships were on the rise.

"Commencement in construction trades is performing strongly, seeing an increase of 8 per cent," he said.

The Master Builders Association Tasmania said earlier this week that it expected the construction sector to grow by about 3000 this year, but warned Tasmania could face a labour shortage when projects in the North and North-West got off the ground.

Late last year, the state government called on any apprentices who fell out of the trade to register online through Skills Tasmania to help fill a skills shortage in the building sector.
