"On a promise given by President Mahinda Rajapaksa it has been decided to establish these two services in the public service with the view to provide assistance in the implementation of the development activities of the government."
The statement said 15,000 graduates will be recruited to Sri Lanka Development Officers Service and 15,000 youths who have passed the General Certificate of Education Ordinary Level examination and "sat for the GCE (A/L)" will be recruited to SL Development Assistants Service.
Both types of recruitment will be from August 01, 2011.
Sri Lanka's public service is hugely overstaffed and inefficient, its ranks bloated by recruitment by successive governments made by both the two main political parties who have ruled the island in order to win votes.
State workers take home over half of tax revenues as salaries and wages.
Members of the public service did not pay income tax on their salaries but that was changed in the government budget for 2011 presented in November 2010.
The statement about the new recruitments did not say how much it would cost the tax payer.
In his budget speech in November, President Rajapaksa, who is also finance minister, said every 100 rupee increase in a state worker's wage adds 1.9 billion rupees in wage and pension benefits a month to the government wage bill.
The new recruitment comes after the expansion of Sri Lanka state workers seen since 2004 flattened in 2010.Total state workers fell slightly to 1,299,102 in 2010, down just 1.1 percent from 1,313,584 in 2009, according to government data.
