Whenever talk of technical education in India comes up, the images invoked are those of the IITs and the NITs, and then may be a few other engineering colleges. Not too much, if anything at all, is said about polytechnics and industrial training institutes. These institutes produce over 150,000 technicians a year, many of them in great demand both in India and abroad. The best of these seem to be the training centres of the Nettur Technical Training Foundation or the NTTF. There are other well-known and well-regarded institutions such as the Government Toolroom and Training Centre and the Indo-German Toolrooms.
