KDA chairman S G Siddaramaiah told reporters in Bengaluru on Thursday that the authority had issued an ultimatum to the agencies asking them to cancel licences of shops without Kannada in their name boards.
"KDA will now write to the government to take stringent measures like withholding promotions of officials or even effecting demotions," he added.
He also expressed confidence that the 21 recommendations made by KDA to strengthen government schools would be taken up at the next Cabinet meeting.
Siddaramaiah said that Primary and Secondary Education principal secretary Shalini Rajneesh had recently assured him that the recommendations would be brought before the Cabinet for consideration.
He also said the government should do away with the Nali Kali programme under Sarva Shiksha Abhiyan (SSA) for primary and higher primary school students, as the Department of Public Instruction had failed to implement it effectively.
He said the programme was unscientific and students were not learning Kannada properly.
