ISRO Recruitment Syllabus — this page explains the long-term, evergreen syllabus structure of the ISRO Recruitment examination conducted by Indian Space Research Organisation (ISRO). Use it to plan a section-wise study calendar; the exact mark-weights and the latest changes for any specific cycle are the ones printed in the official ISRO Recruitment notification PDF on isro.gov.in.

About the ISRO Recruitment syllabus

For Scientist / Engineer SC recruitment, the ICRB syllabus is published in the notification and broadly aligns with the B.Tech curriculum in the eligible discipline plus general aptitude. For Technician, Draughtsman and Scientific Assistant cadres, ISRO publishes a CBT syllabus in the notification covering trade-related subjects and general aptitude at the prescribed level.

ISRO Recruitment is designed to test a combination of subject knowledge, aptitude and language ability appropriate to the cadre being recruited. The official syllabus is published as part of the recruitment notification on isro.gov.in and is the binding document — if any topic on this page differs from the official notification, the official notification prevails.

Section-wise structure of the syllabus

ISRO Recruitment screening stages are typically organised into clear sections so that candidates can build a topic-wise revision plan. Common section themes include:

  • General Intelligence / Reasoning — verbal and non-verbal reasoning, analogies, classifications, series, coding-decoding, blood relations, syllogisms, statement-conclusion, puzzles, seating arrangements and basic data sufficiency.
  • Quantitative Aptitude / Mathematics — number system, simplification, percentage, profit & loss, ratio & proportion, time-work-distance, mensuration, geometry, trigonometry (where applicable), basic statistics and data interpretation.
  • English / General English — reading comprehension, error spotting, sentence improvement, cloze tests, vocabulary (synonyms/antonyms/idioms), para jumbles and basic grammar.
  • General Awareness / General Knowledge — static GK (Indian polity, history, geography, basic science, economy), current affairs of the last 6–9 months and basic computer awareness where prescribed.
  • Subject / Professional knowledge — where the cadre demands it (technical, defence-specific, departmental), a dedicated paper covers the prescribed syllabus from the recognised reference texts.

How to read the official syllabus document

Print the ISRO Recruitment syllabus from the official notification and treat it as a checklist. Tick off each topic only after you can solve a mixed mock on it without referring back to notes. The official syllabus also indicates the standard/level at which questions are set — for example, Class 10 mathematics, Class 12 reasoning, graduate-level English. Always prepare to the standard prescribed in the notification, not above or below it; over-preparation in one area at the cost of another commonly costs serious candidates a section-level cut-off.

Preparation plan recommendations

  1. Foundation (Weeks 1–4): finish NCERT/standard-text-level concepts for each section, with one topic per day and a 15-question recall test at the end of each day.
  2. Practice (Weeks 5–10): shift to chapter-wise question banks for each section. Maintain a small notebook of error patterns and revise it at every weekend.
  3. Mock testing (Weeks 11+): attempt at least one full-length mock per week in the actual exam interface; analyse by topic, not just by score, to find where each minute is leaking.
  4. Current affairs: follow one reliable monthly current-affairs digest end-to-end rather than skim multiple sources. The last 6 months before the exam matter most.
  5. Final two weeks: do not pick a new topic. Consolidate revision notes, attempt previous-year papers under timed conditions and sleep on a fixed schedule.

Sources to use for the ISRO Recruitment syllabus

  • The official ISRO Recruitment notification PDF on isro.gov.in — read the syllabus annexure paragraph by paragraph.
  • Previous years' ISRO Recruitment question papers released officially — they reflect the actual difficulty and topic mix more honestly than commercial guides.
  • NCERT books for foundational concepts in Mathematics, Science, Social Science and English.
  • One standard reference book per section for higher-order practice; do not collect five overlapping titles.
  • A single mock-test platform that mirrors the official exam interface so that you do not lose time learning a new UI on exam day.

Common syllabus mistakes to avoid

  • Treating an old syllabus snapshot from a coaching website as authoritative — the binding document is the syllabus annexure of the current official notification.
  • Skipping reading comprehension practice — long passages account for a significant fraction of the English/language section in most ISRO Recruitment cycles.
  • Ignoring negative marking strategy — selectively skipping low-confidence questions usually outperforms blind attempts.
  • Spending disproportionate time on one section just because it is your strength — section-level cut-offs disqualify candidates with lop-sided scores.
  • Not reading the General Awareness/Current Affairs section seriously — it is high-yield in both screening and main stages.

How to verify any update for ISRO Recruitment

The single authoritative source for ISRO Recruitment updates is the official Indian Space Research Organisation portal at isro.gov.in. Every paragraph on this page is written from the long-term, evergreen structure of ISRO Recruitment — the post profile, the selection process and the broad shape of the syllabus and exam pattern. Specifics such as the exact application window, the cycle-wise vacancy count, the precise application fee, the cut-off marks, the venue allotment, the answer key release schedule and the final result date are always cycle-specific. For those, open the latest official notification PDF on isro.gov.in and read the relevant clause directly.

We refresh this page when Indian Space Research Organisation publishes new ISRO Recruitment information so that the structural details here stay aligned with the latest official guidance. We do not publish unverified release dates, leaked answer keys, rumoured vacancy splits or unofficial cut-off claims. If a date is uncertain, this page will say so plainly and point you to the official notification rather than guess.

Things to avoid while preparing for ISRO Recruitment

  • Do not rely on a single coaching prediction for the application window or the exam date — the only binding source is the official ISRO notification on isro.gov.in.
  • Do not assume that age relaxation, fee or syllabus weightage from a previous cycle automatically applies to the current cycle. Reservation clauses and fee structures are restated in every notification.
  • Do not trust unofficial answer keys, leaked papers or social-media cut-off claims; the official answer key window is the only safe input for raw-score estimation.
  • Do not delay document collection. Class 10, Class 12, graduation, category, EWS, PwBD and ID proofs in the prescribed format should be ready before the application window opens — a missing certificate at verification can lead to disqualification.
  • Do not skip the official mock test on the ISRO portal before the computer-based stage — familiarity with the testing interface saves crucial minutes on exam day.
