Nettur Technical Training Foundation (NTTF) does not have an AICTE approval yet which is needed for your degree to be recognized as valid by other institutions in the country. If you are planning to do higher studies after the diploma from NTTF, then you may not get opportunities as it is not recognized. There is no point in doing a degree that is not recognized.

However, if you are looking for just a job after the course and nothing else, then it is good. It has good placement records and you will get ample opportunities for the same. I would say think twice before coming to this college if you are still not sure whether you are doing this course for just a job or higher studies.
