Who is Eligible for SSC IMD Scientific Assistant? (Detailed Criteria)
Unlike general graduate-level examinations like SSC CGL or CHSL, the Scientific Assistant post has rigorous technical qualification clauses. To avoid disqualification at the stage of Document Verification, candidates must ensure they meet all four essential conditions below:
1. Essential Educational Qualification (Any ONE of the following):
- Bachelor's Degree in Science (B.Sc.): Must have studied Physics as one of the compulsory subjects for at least two years (or across all semesters) from a recognized University.
- Bachelor's Degree in Computer Science / IT / Computer Applications: Candidates holding B.Sc. (Computer Science), B.Sc. (Information Technology), or BCA (Bachelor of Computer Applications) from a recognized institution.
- Diploma in Electronics & Telecommunication Engineering: A 3-year Diploma after 10th standard, or a 2-year lateral entry Diploma after 10+2, recognized by AICTE or State Technical Boards.
- B.E. / B.Tech Degrees: Degree holders in Computer Science, IT, Electronics, Electronics & Communication (ECE), Telecommunication, or related disciplines are eligible as equivalent qualifications.
2. Mandatory 10+2 (Intermediate) Subject Mandate (Critical):
The candidate MUST have passed the 10+2 (Higher Secondary / Intermediate) examination with both Mathematics and Physics as subjects from a recognized Board.
Important: If a candidate studied Biology or Arts in 10+2 and subsequently pursued BCA, they are NOT eligible under the official recruitment rules.
3. Minimum 60% Aggregate Marks or 6.75 CGPA:
Candidates must have secured at least 60% marks in aggregate (or a CGPA of 6.75 on a 10-point scale) in their qualifying degree or diploma. Candidates with less than 60% (e.g. 59.9%) are not considered eligible as there is no rounding-off allowed.
4. Medical & Physical Standards:
Candidates must possess sound mental and bodily health. Crucially, normal color vision is required because Scientific Assistants interpret multi-spectral satellite images, radar Doppler reflectivity graphs, and weather maps where color discrimination is essential.
Age Limit & Category-Wise Relaxations
The standard prescribed age limit for the SSC IMD Scientific Assistant post is 18 to 30 years as on the crucial date of eligibility mentioned in the official notification. Candidates must have been born not earlier than the specified date and not later than the lower age cutoff.
| Category | Age Relaxation Permitted | Maximum Permissible Age |
|---|---|---|
| Unreserved (UR) / EWS | No relaxation | 30 Years |
| OBC (Non-Creamy Layer) | 3 Years | 33 Years |
| Scheduled Caste (SC) / Scheduled Tribe (ST) | 5 Years | 35 Years |
| PwD (Unreserved / EWS) | 10 Years | 40 Years |
| PwD (OBC) | 13 Years | 43 Years |
| PwD (SC / ST) | 15 Years | 45 Years |
| Ex-Servicemen (ESM) | 3 years after deduction of military service from actual age | As per Govt Rules |
| Central Govt Civilian Employees (General) | Up to 35 years of age (min 3 years continuous service) | 35 Years |
* Note: The date of birth recorded in your Secondary School / Matriculation Certificate is accepted as the final proof of age.

Part II: Technical Discipline (Domain Specific) — 100 Questions | 100 Marks
During application submission, candidates must choose ONE discipline matching their academic stream:
| Optional Technical Discipline | Questions | Marks | Standard / Level |
|---|---|---|---|
| Discipline 1: Physics | 100 Questions | 100 Marks | B.Sc. Degree Standard |
| Discipline 2: Computer Science & Information Technology | 100 Questions | 100 Marks | B.Sc. CS / BCA / Degree Standard |
| Discipline 3: Electronics & Telecommunication Engineering | 100 Questions | 100 Marks | Diploma / Degree Standard |
Negative Marking Rule
Each incorrect answer incurs a deduction of 0.25 marks (one-fourth of the mark assigned). Questions left unanswered attract no deduction.
Multi-Shift Normalization
Because the exam is conducted across multiple shifts with varying difficulty in Part II, raw marks are normalized using the standard Commission formula before finalizing merit.

SSC IMD Scientific Assistant: Last 5-Year Cutoff Trends & Score Analysis
Understanding previous cutoff benchmarks is crucial for goal setting. Below are the official normalized cutoff marks out of 200 for the computer-based exam across recent cycles:
| Category | 2022 CBE Official Cutoff | 2017 CBE Cutoff | Recommended Safe Score (2026) |
|---|---|---|---|
| Unreserved (UR) | 138.64 | 138.00 | 146 – 152 |
| OBC (Non-Creamy) | 130.54 | 128.75 | 138 – 144 |

Strategic Insight for 2026 Aspirants:
1. Consistency of Cutoff: Notice that UR cutoff hovered around 138 marks in both 2017 and 2022 despite increased applicant numbers. This occurs because the technical Part II paper maintains rigorous standards that prevent score inflation.
2. Scoring Part I vs Part II: Successful candidates typically score 75–82 marks out of 100 in Part I (Reasoning, English, and Maths are high scoring) and 65–70 marks in Part II technical discipline to comfortably clear the final merit barrier.
