The Government's flagship employment scheme faced fresh criticism when a study by MPs showed how it was "failing".
A report for the Public Accounts Committee about the Work Programme said the number of people moving off benefit into sustained employment was less than a third of the level expected.
The National Audit Office said in its report that no external providers involved in the programme met minimum performance levels set in their contracts.
For jobseeker's allowance claimants under the age of 25, the best-performing provider achieved 2.2% into work to the end of March, compared with a target of 5.5%, while the worst achieved 0%, it was reported.
The Government faced calls to scrap the scheme last month after revealing that only 3.5% of those taking part had found sustainable jobs.
Department for Work and Pensions figures showed that 800,000 people had started the Work Programme since it was launched last year, but only 31,000 stayed in a job for six months.
Margaret Hodge, who chairs the Public Accounts Committee, said: "This first analysis of the performance figures shows the extent to which the scheme is failing participants, and particularly the young and the harder to help.
"The Work Programme was specifically designed to incentivise providers to assist those furthest from the workplace, but the appalling performance for Employment Support Allowance ex-incapacity claimants demonstrates how this experiment simply is not working."
