Critics said the figures showed that Coalition ministers had thrown hundreds of staff on the dole queue.
A total of 1795 Remploy workers have lost their jobs across the UK, including 270 in Scotland.
In a parliamentary written answer the Department of Work and Pensions said that just 535 former employees were in work.
Last night the Department for Work and Pensions said that the figure related to the 1326 former staff who took up an offer of help to find work and did not mean the others were unemployed.
But Pamela Nash, the Labour MP for Airdrie and Shotts, who obtained the figures, said they suggested that up to two-thirds of workers could be out of a job.
She said: "The Government's record on Remploy is nothing short of a disgrace.
"This is very sad news for these workers and their families, who were made unnecessarily unemployed, when there were alternatives open to the Government to keep them in work. The fact that around two-thirds of these workers could still be out of work makes a mockery of the Government's work programme, which clearly isn't living up to its name.
"The Government's record on disability employment in general is one of failure; Iain Duncan Smith dumped these Remploy workers on the dole queues against Labour warnings, and as these figures show they are sadly more likely to still be there."
The decision to shut the Remploy factories has proved controversial.
More than two dozen sites across the UK have been affected, including all 10 in Scotland, according to the DWP.
Opposition parties have accused ministers of throwing disabled workers on the scrap heap, while the minister who was in charge of the closure programme was dubbed "Maria Miller, factory killer".
The Coalition attempted to offset criticism by saying that it would help former Remploy staff find other jobs.
A DWP spokesman said that in the first stage of redundancies in Scotland in which 108 people lost their job, 63 had been found another position.
He said: "We put in place an £8 million package of employment support for ex-Remploy workers, including a network of 200 personal case workers to help individuals with their future choices, as well as access to a personal budget.
"The tailored package is already making a real difference to disabled people by supporting them into new careers - with many taking on mainstream jobs in a variety of sectors.
"We'd encourage anyone leaving Remploy to take up the support."
