The Indian Space Research Organisation (ISRO) recruits candidates for the Upper Division Clerk (UDC) position through a competitive selection process involving a written test and skill test. Candidates must hold a Bachelor’s degree in any discipline with at least 60% marks and possess basic computer proficiency. The UDC role falls under Level 4 of the 7th Central Pay Commission, offering a starting basic pay of Rs. 25,500 plus applicable allowances. The selection is based on merit in the objective-type written examination. Eligible Indian citizens can apply online via the official ISRO recruitment portal when the notification is active for 2026.
The ISRO UDC recruitment is conducted by the Indian Space Research Organisation, adhering to a well-defined selection framework designed to identify the most suitable candidates for administrative roles. The process is conducted at a national level, primarily focused on specific zones—in this case, the Bangalore zone—to fill designated vacancies. The mode of the examination is a written test, which serves as the primary gateway for entry into the organization, supplemented by a subsequent skill test stage.
The examination structure is highly systematic, consisting of four primary subjects: General English, Quantitative Aptitude, General Intelligence & Reasoning, and General Knowledge. Each of these sections is weighted equally, with 50 questions assigned to each, leading to a cumulative total of 200 marks. Candidates are allotted a composite duration of 120 minutes to complete the entire paper, which tests not only their domain knowledge but also their time management and speed. Furthermore, the inclusion of a negative marking scheme, where 0.25 marks are deducted for every incorrect response, necessitates high accuracy and careful preparation. To qualify for further consideration, candidates must achieve the minimum benchmark set for their respective categories, which currently stands at 50% for the Unreserved (UR) category and 40% for candidates belonging to reserved categories. This multi-stage approach ensures that only the most proficient candidates are inducted into the organization.
