The Graduate Aptitude Test in Engineering (GATE)

The Graduate Aptitude Test in Engineering (GATE) conducted by IISc and IITs has emerged as one of the bench mark tests for engineering and science aptitude in facilitating admissions for higher education (M.Tech./Ph.D.) in IITs, IISc and various other Institutes / Universities/ Laboratories in India. With the standard and high quality of the GATE examination in 23 disciplines of engineering and science subjects, it identifies the candidate’s understanding of a subject and aptitude and eligibility for higher studies. During the last few years, GATE score is also being used as one of the criteria for recruitment in Government Organizations such as Cabinet Secretariat, and National/State Public Sector Undertakings in India. Because of the importance of the GATE examination, the number of candidates appearing in GATE exams has increased tremendously and this year (GATE 2017) more than 9.23 Lac candidates have applied for the examination. GATE exams are conducted by the IITs and IISc as a computer based test having multiple choice questions and numerical answer type questions. The questions are mostly fundamental, concept based and thought provoking.

This year GATE 2017 shall also hold examinations for candidates in Bangladesh, Ethiopia, Nepal, Singapore, Sri Lanka, and United Arab Emirates. India is a great destination for foreigners for higher studies with world class Institutes such as IITs, IISc, IISERs, Central Universities etc., with high quality education, international recognition of degrees, English medium of instructions, affordable fees and living conditions, availability of high-end lab facilities etc. An Institute with various nationalities in its campus widens the horizons of an academic environment. We also believe that a foreign student brings with him/her a great diversity, culture and wisdom to share. Many GATE qualified candidates are paid scholarships/assistantship, especially funded by Ministry of Human Resources Development, Government of India and by other Ministries. GATE examination provides with a GATE score to all qualified candidates, which is valid for three years, but does not take any responsibility of admission of any candidate to any Institute. GATE is one of the opportunities to make career advancement, and certainly not the only one.
