Yes they have succeeded in attracting people to join their courses. But the quality of education is nothing less than crap. In a country of ours, not even engineering colleges, barring IIT's, may claim to impart quality IT education, leave alone NIIT. More often than not those who teach are the ones who have 'graduated' from these NIIT courses and i see no way they are going to get quality people with industry experience teaching on their campus because, no matter, how much money they get from unsuspecting students they are not going to bother spending them for quality. And that may be because students have no options to go for, once enrolled, as other institutes, big or small, are as crap as NIIT.
Need of the hour is to regulate these practices before they assume criminal proportions. Is some one listening!
