Mr Rawat said that the three Election Commissioners are likely to visit Karnataka in the first week of April to assess the situation and check its poll-preparedness.
The tenure of the Karnataka assembly expires on May 28 and before that, the new house has to be constituted, Mr Rawat told NDTV.
The commission, he said, is "keeping in mind the interest of school children" this time. "School board examinations likely to be over by the end of March and other examinations around 14 April... keeping that in mind, we will announce the poll dates around 15 April," he added.
Mr Rawat said he was "pained" to hear the children's complaint. The by-polls in Gorakhpur and Phulpur Lok Sabha seats could have been held earlier, he said, but there was a delay in publishing the electoral rolls.
"Usually the Election Commission publishes revised rolls by January. But in Uttar Pradesh, it got delayed and was published in February," he said. Since the poll process has to be completed by March 20, they decided to hold in on March 11.
