It actually does not matter whether you rename some RECs as IITs. IITs and RECs are anyway a class of their own. They are no doubt the best engineering schools of India and some of the very good all over the world. Whereas most IITs are awesome, some RECs like Trichy, Suratkhal, Allahabad, Bhopal and Warangal have shown their might as well. What we need is to bring out these schools as best and work towards their betterment. These RECs did an awesome job even when they were not named NITs/IITs. So what i basically think is that instead of having more IITs, the IITs, these few RECs, BITS etc should have a JEE(Joint entrance exam) and students may choose amongst these schools. This will put them at par(which they already are) and then they will get the best of Indian Students and then that will be fair as well.....so renaming.....just an unnecessary exercise.
