The Graduate Aptitude Test in Engineering
The Graduate Aptitude Test in Engineering
Graduate Aptitude Test in Engineering (GATE) is an examination that primarily tests the comprehensive understanding of various undergraduate subjects in engineering and science for admission into the Masters Program and Job in Public Sector Companies. GATE is conducted jointly by the Indian Institute of Science and seven Indian Institutes of Technologies at Roorkee, Delhi, Guwahati, Kanpur, Kharagpur, Chennai (Madras) and Mumbai (Bombay) on behalf of the National Coordination Board - GATE, Department of Higher Education, Ministry of Education (MoE), Government of India.
Organising Institute for GATE 2023 is Indian Institute of Technology (IIT) Kanpur.
Eligibility criteria is relaxed. A Candidate who is currently studying in the 3rd or higher years of any undergraduate degree program OR has already completed any Government approved degree program in Engineering / Technology / Architecture / Science / Commerce / Arts is eligible to appear for GATE-2021 examination. There is NO age limit to appear for GATE 2023 examination.
The GATE score of a candidate reflects the relative performance level of a candidate. The score is used for admissions to various post-graduate education programs (e.g. Master of Engineering, Master of Technology, Master of Architecture, Doctor of Philosophy) in Indian higher education institutes, with financial assistance provided by MHRD and other government agencies. Recently, GATE scores are also being used by several Indian public sector undertakings for recruiting graduate engineers in entry-level positions. It is one of the most competitive examinations in India. GATE is also recognized by various institutes outside India, such as Nanyang Technological University in Singapore.
It is important to check before starting an application for GATE exam whether candidates meet the eligibility criteria or not. Every Year few modifications in eligibility criteria take place.
