The committee, headed by former Karnataka chief minister Veerappa Moily, was earlier scheduled to meet on September 15 to finalise its report.
"This is a sensitive and significant issue. It is of national importance. The committee wants to have a cautious approach," Moily said, adding the meeting would be held on September 27.
The panel would like to submit its final report by the month end, said Moily, who is also chairman of the Administrative Reforms Commission.
Moily, who held a series of consultations last month with academicians in preparation for finalising the report, had earlier indicated that the implementation of the 27 per cent quota was possible only in a staggered manner.
The committee is also expected to give its "considered view" on the "creamy layer" issue in its final report.
