The scheme, which it is hoped will create at least 1,000 new jobs in the third sector for young people in Scotland between May 2013 and March 2014, is in its second year.
It will allow third sector organisations to offer 800 39-week placements to unemployed 16 to 19-year-olds, with 200 additional placements of at least 26 weeks for young people aged up to 24 who are disabled or who face additional barriers to employment. The maximum funding for each employee is £5,250.
The scheme was extended in February with a grant of £5.75m from the Scottish government.
It previously received a grant of £9.5m and has already secured 3,206 positions, the SCVO said.
John Downie, director of public affairs at the SCVO, said: "We’re encouraging third sector organisations in all of Scotland’s 32 local authorities that are interested in recruiting a CJS employee to get in touch."
The deadline for applications is 30 April.
