The Ceylon Civil Service, popularly known by its acronym CCS, originated as the elite civil service of the Government of Ceylon under British colonial rule and on after independence, until the 1970's when it was abolished and the much larger Sri Lankan Administrative Service was created which is now the key administrative service of the Government.
At the early days the CCS was staffed by members of the British Civil Service and later Ceylonies were admitted. During Civil Service days, only 6 to 8 (some years it was only 1) out of a very large number of applicants were selected by open competitive examination from graduates with first class honors, between the ages of 22 and 24 and this ensured the cream of talent to hold the top non-elected positions of government. This was very important since like the British Civil Service,appointments to top non-elected positions of government are permanent and politically neutral character of the civil service. Due to this the officers of the CCS commanded a high amount of respect even today. The British civil service is the permanent bureaucracy that supports the Government Ministers responsible to the Sovereign and Parliament in administering the United Kingdom. ...
