An independent review of the trade training centres in schools program is underway.
Economist Patricia Scott will lead the review of the federal government-funded centres introduced in 2010.
It includes one at Loyola Senior High School in Mt Druitt, where about 60 per cent of enrolled students combine a first year trade apprenticeship with HSC study.
Lindsay federal MP Fiona Scott said people in industry were concerned there were inconsistencies between centres in the quality of training, qualifications and equipment offered.
"These Trade Training Centres are operating with 20-year contracts, so our review is about ensuring they deliver taxpayers and students maximum value going forward," she said.
"We need to get more of our kids into trades and training if we're going to address skills shortages, but training needs to be high-quality and include on-the-job experience to be effective."
Loyola's assistant principal for vocational programs, Tammy Prestage, said teachers and others from the centre would give their input to the review.
She said 97 per cent of the school's trade training centre graduates in 2013 had successfully completed a first year apprenticeship, compared to the national average of about 50 per cent.
Ms Prestage said she had recently taken part in a round table discussion on the topic with employers and others from greater western Sydney.
