What is GATE?

GATE (Graduate Aptitude Test in Engineering) is an All-India entrance test managed and authorised in eight national regions. The GATE Committee conducts the exam, faculty members of IITs and IISc on behalf of the Ministry of Human Resource Development, Department of Education and National Coordinating Board. The primary goal of the GATE exam is to test students’ knowledge and awareness in subjects like Science and Engineering.

Multiple Public Sector Undertakings use the GATE scorecard in order to recruit applicants for distinguished jobs at GAIL, Hindustan Petroleum, Indian Oil, etc.

GATE Eligibility Criteria

The GATE Eligibility requirement is based on various parameters such as education qualification, age, nationality, etc. 

  • The minimum qualification required for applicants is 10+2+3, i.e. the students must have completed their Bachelor’s degree. 
  • Candidates who have certification from any of the professional societies, however, must ensure that the examinations administered by the societies are recognised by the MoE/AICTE/UGC/UPSC as equal to B.E. / B.Tech. / B.Arch. / B.Planning, etc.
  • Candidates who have achieved or are pursuing their qualifying degree outside of India: Must be in their third or higher year of study or have obtained a Bachelor’s degree in Engineering / Technology / Science / Arts / Commerce.
  • Indian students are eligible. International candidates from Nepal, Bangladesh, Singapore, Sri Lanka, Ethiopia and United Arab Emirates (UAE) will also be eligible.
  • A candidate who is currently studying in the final year of the undergraduate degree or who has already completed the UG degree in Engineering/ Technology/ Commerce/ Arts/ Science/ Architecture.
  • There is no attempt limit; candidates just have to meet the eligibility criteria for GATE.
  • There is no maximum or minimum age limit for all the GATE aspirants enrolling in the GATE exam.
