About GATE

The Graduate Aptitude Test in Engineering (GATE) is an All-India examination administered and conducted in eight zones across the country by the GATE Committee comprising of Faculty members from IISc, Bangalore and other seven IIT’s on behalf of the National Coordinating Board, Department of Education, Ministry of Human Resources Development. The GATE score/rank is used for admissions to Post Graduate Programmes (ME, M.Tech, MS, direct PhD) in institutes like IIT and IIScetc with financial assistance offered by MHRD. PSUs too use the GATE scores for recruiting candidates for various prestigious jobs with attractive remuneration.

In GATE examination, candidates can apply for only one of the 24 papers listed in the table given below. Candidates are expected to appear in a paper appropriate to the discipline of their qualifying degree. However, candidates are free to choose any paper according to their admission plan, keeping in mind the eligibility criteria of the institutions in which they wish to seek admission. For more details regarding the admission criteria in any particular institute, candidates are advised to refer to the websites of that particular institute.
