• Graduate Aptitude Test in Engineering (GATE) is an all India examination that primarily tests the comprehensive understanding of the candidate in various tests undergraduate subjects in Engineering/Technology/Architecture and postgraduate level subjects in sciences.
• The GATE score of a candidate reflects a relative performance level in a particular subject in the exam.
• The score is used for admissions to post-graduate programs  (eg. M.E., M.Tech, direct Ph.D.) in Indian institutes of higher education with financial assistance provided by MHRD and other Government agencies.
• The score may also be used by Public and Private Sector Undertakings for employment screening purposes.
• The Indian Institute of Science (IISc) and seven Indian Institutes of Technology (IITs  at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras and Roorkee) jointly administer the conduct of GATE. The operations related to GATE in each of the 8  zones are managed by a Zonal GATE Office at IISc. or IITs. The Organizing Institute  (OI) is responsible for the end-to-end process and coordination amongst the  administering Institutes. The Organizing Institute for GATE 2014 is IIT Kharagpur.

Financial Assistance

• A valid GATE score is essential for obtaining financial assistance during Master’s  programs and direct Doctoral programs in Engineering/ Technology/ Architecture,  and Doctoral programs in relevant branches of Science in Institutes supported by  the MHRD or other Government agencies. As per the directives of the MHRD, the  following procedure is to be adopted for admission to the post-graduate programs  (Master’s and Doctoral) with MHRD scholarship/ assistantship. Depending upon the  norms adopted by a specific institute or department of the Institute, candidate may  be admitted directly into a course based on his/her performance in GATE only or  based on his/her performance in GATE and an admission test/interview conducted  by the department to which he/she has applied and/or the candidate’s academic  record. If the candidate is to be selected through interview for post-graduate  programs, the minimum of 70% weightage will be given to the performance in GATE  and the remaining 30% weightage will be given to the candidate’s performance in  interview and/or academic record, as per MHRD guidelines.

• The admitting institutes  could however prescribe a minimum passing percentage of marks in the  test/interview. Some colleges /institutes specify GATE qualification as the mandatory  requirement even for admission without MHRD scholarship/ assistantship.
• To avail of the financial assistance (scholarship), the candidate must first secure  admission to a program in these Institutes, by a procedure that could vary from  institute to institute. Qualification in GATE is also a minimum requirement to apply  for various fellowships awarded by many Government organizations. Candidates are  advised to seek complete details of admission procedures and availability of MHRD  scholarship/assistantship from the concerned admitting institution. The criteria for  postgraduate admission with scholarship/ assistantship could be different for  different institutions. The management of the post-graduate scholarship/  assistantship is the responsibility of the admitting institution. Similarly, reservation  of seats under different categories is as per the policies and norms prevailing at the  admitting institution and Government of India rules. GATE offices will not entertain  any enquiry about admission, reservation of seats and/or award of  scholarship/assistantship.
