Mrs Bennett said sole parents with no qualifications spend an average of 17 years on welfare, compared to 7.5 years for a sole parent with a tertiary qualification.
The policy partly reversed changes made in welfare reforms last term, in which the Government scaled back access to the training incentive allowance. This was a controversial change at the time because Ms Bennett received the allowance when she was a solo mother.
The training incentive allowance, at current rates, is worth $106 a week.
As part of the new changes, the Government planned to allow sole parents to continue receiving child support while they claimed a temporary benefit during academic breaks.
It will also abolish a one- to two-week stand-down period for support which occurs when students begin their academic break.
The change to child support and the abolition of the stand-down period will require a law change, and won't be in place until the end of 2016.
