The Indian Space Research Organisation (ISRO) recruits Scientific Assistants through a competitive written examination followed by a skill test. Candidates must hold a Diploma in Engineering in the relevant discipline with at least 60% aggregate marks to be eligible. The position falls under Level-7 of the 7th CPC Pay Matrix, offering a competitive starting salary plus admissible allowances. Selection is based purely on merit performance in the Computer Based Test (CBT). ISRO conducts this recruitment periodically across various centres like VSSC, URSC, and SAC to support space research operations. Interested applicants must monitor the official ISRO career portal for specific notifications and application deadlines.
The ISRO Scientific Assistant recruitment is conducted by the Indian Space Research Organization, specifically managed under the Satish Dhawan Space Centre. The examination is aimed at filling specific technical roles. The entire process is conducted online, starting from the application submission phase. The authority ensures a merit-based selection process that emphasizes both academic background and technical expertise.
The examination structure is divided into two primary stages: a written test and a skill test. The written test serves as the first hurdle, consisting of objective-type multiple-choice questions (MCQs). Candidates who qualify the written examination move on to the skill test, which is technical in nature and is primarily designed to assess the candidate's practical capabilities. Following the successful completion of these stages, document verification is performed to validate the candidate's eligibility and credentials. This systematic approach ensures that only the most capable individuals are inducted into the organization. Candidates must stay updated with official announcements and adhere strictly to the guidelines provided by the recruiting body to ensure their candidature remains valid throughout the selection process.
