Admission to Indian Institute of Technology (IITs) or National Institute of Technology (NITs) Without GATE score (NON-GATE):
Most of the students cannot imagine going to IITs without tough completion, which is a correct assumption. But there are ways to get into IITs and NITs without GATE scores too. Below are the possible cases. Sponsored Candidates: If you are working in industry for over three year and can prove that your employer is ready to allow you to go to study by letters from authority, you can apply under this category. There are few seats reserved under this category in both IITs and NITs. Quality Improvement programme (QIP): This is started by government. Of India to improve the quality of teaching staff in state colleges by giving them a chance to attend India's top most engineering schools. All the faculty members with three years plus experience are eligible for this. Kindly read the upcoming post giving detail view of these programs. Admission to Indian Institute of Information Technology (IIITs):
They conduct their own exam for admission. Anyone can apply and try to get admission for Master of Engineering. These colleges are deemed universities and have good infrastructure and placements. Admission to Central and State Universities:
Few Central Universities conduct there own exams and few consider GATE scores too. Most of the State University doesn't get GATE qualified students, therefore they conduct their own written test and interview. For more information about notification and other details please subscribe via email, check the box on upper right side of this page. For a list of central universities offering M.Tech programs visit Master of Engineering Degree (M.Tech) in Central Universities. Private Deemed Universities:
These days in India there are many professional private universities offering Masters in engineering. They conduct their won exam and interview. Admission is easy but they may charge huge fee. Private Engineering colleges offering Master of Engineering:
AICTE approve many old private engineering colleges to start M.Tech course because of infrastructure and faculty. Admission these are easy but may be expensive. List of colleges/University where you can apply for M.Tech without GATE score:
Aligarh Muslim University
Banaras Hindu University of Delhi

NIFT conducts its own entrance exam which happens in two stages:
1. General Ability Test (GAT)-This exam comprises 4 sections namely Quantitative Ability, Logical Reasoning, English Language Comprehension and General Knowledge.
2. Creative Ability Test CAT This test is administered to judge the intuitive ability, power of observation in concept development and design ability of the candidate. An important aspect of the test is the creative and innovative use of colour & illustration skills. Both the tests are important and mandatory to attend. Both take place on the same day and it's for all because NIFT has compulsory entrance test so a student who wants to take admission has to go through the test without the test and clearing it cannot go through so yes the fee for NIFT students and entrance exam is a must.
