Lucrative training contracts for the Australian Federal Police and the Department of Defence have been awarded to a private college group that has been under investigation by the federal government.

The new contracts between ACTE, trading as Evocca, and the Department of Defence and the AFP come after the college graduated just 12 per cent of students over a three-year period while earning $180 million in taxpayer-funded student loans under the scandal plagued VET FEE-HELP scheme.

A spokeswoman for the AFP said the selection of the training provider "met all government purchasing and procurement requirements".

The tenders, worth more than $200,000, have been awarded under several different company names, including Dimension Data Learning Services, to supply training for less than five months in software courses, electrical services and general training.
