NEW DELHI: The HRD Ministry has directed the Indian Institutes of Technology (IITs) to come up with a revenue model for their operations. The move comes after the IIT directors had approached the ministry, saying the 122 per cent fee hike introduced last year did “no good” to the institutes revenue-wise as lots of concessions were announced simultaneously. The issue was also on the agenda of the meeting of the IIT Council, the apex coordination body of 23 IITs, in Mumbai last week. PTI
