"Because they are less likely to leak confidential documents"
According to a report in The Star Online:
Only a minimum primary education is required for office boy and general office assistant positions in state departments here because those with lower education are less likely to take risks that can lead to disciplinary action.
The state government has maintained the minimum qualification set by the British to prevent the leakage of highly classified and confidential documents.
The English daily quoted Chief Minister Idris Haron as saying:
"Initially, the state was perplexed as to why the British had set a minimum requirement for such positions at the primary level, but now we understand."
Idris added that the state government had been warned to be careful of confidential documents being leaked.
Idris further said that those with lower education would normally cherish the government job and would be less likely to take any risk
