SDSC SHAR 2026 Technical, Scientific, Library and Trade CBT

SDSC SHAR Technical, Scientific, Library and Trade Examinations — Official Scheme and Post-Wise Preparation

Quick route check: This page is ONLY for codes 07–14 and 16–25. Written CBT: 80 MCQs, 90 minutes, −0.33 negative marking. After CBT: a 100-mark qualifying skill test; written marks decide merit. The source provides a prescribed-disciplinary curriculum but no official topic-by-topic chapter list for all 18 post codes.

Advertisement: SDSC SHAR/RMT/03/2026 (19 October 2026). Eligible post codes: 07–14 and 16–25. This is the selection route for Technical Assistant, Scientific Assistant, Library Assistant 'A', Technician 'B' and Draughtsman 'B'. It does not apply to Nurse 'B', Fireman, Drivers or MTS, which have separate patterns. The authority describes the technical/trade syllabus as theoretical and practical knowledge covering the breadth and depth of the prescribed curriculum. It does not provide an independent chapter-by-chapter technical syllabus for each of these 18 codes in this advertisement. Official advertisement PDF, pp. 1–5, 13–14.

Official written-test pattern

Calculation, not an official cut-off: 52 correct answers, 12 wrong answers and 16 unattempted give 52 − (12 × 0.33) = 48.04 written marks. The notified 32/80 or 24/80 figures are minimum qualifying marks, not the marks needed for actual selection or a category-wise final cut-off. Actual merit depends on written-test ranking and vacancies.

Post-code-specific eligible curriculum and credential gates

The rows below identify the official qualification/discipline against which the prescribed curriculum will be assessed. They are not an invented ISRO chapter list. 'First Class' and the required combined qualifications must be checked before preparing.

For code 17, the five permitted trades in the notice are Chemical, Attendant Operator (Chemical), Instrument Mechanic (Chemical), Maintenance Mechanic (Chemical Plant), and Laboratory Assistant (Chemical). The broad label 'Chemical' cannot be taken to mean that any chemistry or lab qualification is eligible. Technical Assistant diploma duration is explicitly at least three years. A Library Assistant needs both graduation and the qualifying Master's; a Master's alone does not replace the graduation condition. Qualifications: PDF pp.1–5.

Syllabus-status distinction: official scope versus suggested revision

Officially confirmed: Each code is assessed for its own prescribed educational/trade curriculum; the same 80-question marking rule applies across the technical, scientific, library and trade group. Not published here: a separate chapter-weightage table, count of questions per technical subject, particular textbook, detailed practical tasks, and dates of the test. Do not present any such details as an official ISRO blueprint.

Suggested revision (editorial guidance, not notified topics): Code 07 candidates can review core diploma mechanical principles relevant to their completed curriculum; code 08 electrical and electrical-electronics fundamentals; code 09 computer-science engineering concepts; codes 10–11 the respective electronics/civil diploma material; code 12 the notified Physics-main, Mathematics-ancillary and Chemistry-ancillary subject combination; code 13 photography/cinematography fundamentals; code 14 library/information-science degree concepts; codes 16–25 their exact NCVT trade theory and practical concepts. These are curriculum-based preparation suggestions, not a claim that ISRO has published those chapters or their weightage.

Skill test, shortlist and final merit

1. On written performance, candidates are shortlisted category-wise at 1:5 against vacancies, subject to at least 10 candidates; calls may be made in batches (PDF pp.13–14).
2. Skill test: 100 marks, qualifying only. The notified pass standards are 50/100 (UR) and 40/100 (eligible reserved candidates against reserved vacancies). Skill marks do not enter final rank.
3. The panel is ordered by written-test scores among skill-qualified candidates. Written-score ties are resolved first through the academic marks of the essential notified qualification; if necessary, older age ranks ahead.
4. A candidate can exceed the written qualifying floor but still fail to obtain the skill-test shortlist because the ratio and seat-specific written ranking apply. Conversely, scoring highly on skill does not compensate for a lower written rank.

Candidate checklist and recruitment links

• Check the precise post code and recognition/class/duration/trade before choosing a paper; a Technician (Fitter) credential cannot be assumed valid for a Civil Engineering Assistant post.
• Revise by the notified discipline rather than downloading a generic all-trades syllabus labelled 'official'.
• Use the SarkariSapna government exams directory for separately published exam records and the SarkariSapna syllabus directory for officially linked syllabi; an individual SDSC exam date or detailed technical-topic PDF was not announced in this 43-page advertisement.
• To compare recruitment eligibility, explore diploma-level recruitment listings or ITI-level recruitment listings. These are general site directories, not proof of an SDSC-specific study course.
• Return to the parent SDSC SHAR 97-vacancy recruitment for post-code fees, age, reservation, posting and application details. Parent article link is operational after this recruitment is published.
