DSSSB ASO 2026 Syllabus Exam Pattern Subject Wise Topics are set out below from the current DSSSB Advertisement No. 01/2026 for post code 804/26, Grade-II (Assistant Section Officer). The earlier single-tier summary on this page was incomplete. The current notice provides a two-tier scheme, so candidates should prepare Tier I objective subjects as well as Tier II computer and descriptive components.
Exam pattern and marks
For post code 804/26, the official advertisement describes a two-tier examination. Tier I is a 200-question objective paper. Tier II combines a 200-question objective paper with 100 descriptive marks. The official advertisement should be downloaded from the Important Links section below before the examination.
| DSSSB ASO exam pattern | Questions / marks | Duration |
|---|---|---|
| Tier I | 200 MCQs for 200 marks. | 2 hours. |
| Tier II objective | 200 MCQs for 200 marks. | 3 hours, one session with Part II. |
| Tier II descriptive | 100 marks, essay 50, letter 25 and précis 25. | Held within Tier II. |
| Negative marking | 0.25 marks cut for each wrong 1-mark MCQ. | Both tiers. |
Note: Tier I has 40 questions each on General Awareness, Reasoning, Numerical Ability, Hindi and English. Tier II objective has 40 each on General Awareness, Reasoning, Numerical Ability, English Language and Computer Proficiency. The descriptive paper covers an essay or idea expansion in English, a letter or application, and a précis. Every MCQ carries 1 mark and a wrong answer costs 0.25, so four wrong answers wipe out one correct one.
Qualifying marks and ASO vacancies

Note: The advertisement lists the three ASO departments as separate rows and gives no single ASO total. The 587 and the category split are our sums of those rows, which the Board calls tentative. Tier I only shortlists for Tier II. The final merit uses the 300 Tier II marks, and the qualifying cut is applied to Part I and Part II together. Applications ran from 24.02.2026 to 25.03.2026.

Tier I syllabus subject wise
The notice names the five Tier I sections. The topic list below is a preparation map for those named sections; the official Advertisement No. 01/2026 is the final authority for ASO Post Code 804/26. The generic DSSSB Scheme & Syllabus directory should not be treated as an ASO-specific page because it can open syllabus entries for other posts.
| Tier I subject | Questions / marks | Topics |
|---|---|---|
| General Awareness | 40/40 | Current affairs, history, geography, polity, economy, science, culture, sports, national events |
| Reasoning | 40/40 | Analogy, series, coding-decoding, blood relations, directions, syllogism, Venn diagrams, statements, arrangements, non-verbal |
| Numerical Ability | 40/40 | Number system, simplification, percentage, ratio, average, profit and loss, interest, time and work, speed-distance, mensuration, data interpretation |
| Hindi | 40/40 | Grammar, vocabulary, error correction, synonyms-antonyms, idioms, sentence correction, comprehension |
| English | 40/40 | Grammar, error spotting, vocabulary, fill in the blanks, sentence improvement, cloze test, para arrangement, comprehension |
Note: Reasoning is General Intelligence and Reasoning. Hindi and English are Language and Comprehension papers. History, geography and polity are Indian.
Tier II syllabus and computer proficiency
Tier II changes the preparation strategy because it adds computer proficiency and a descriptive English component. Candidates should practise accuracy-based objective questions and separately build writing speed. Do not treat the older five-section single-tier table as the complete 2026 pattern.
| Tier II component | Topics |
|---|---|
| General Awareness | Current affairs, government, polity, history, geography, economy, science |
| Reasoning | Series, coding, classification, arrangements, statements |
| Numerical Ability | Arithmetic, quantitative comparison, data interpretation |
| English | Grammar, vocabulary, comprehension, sentence correction, usage |
| Computer Proficiency | Fundamentals, OS and files, word processing, spreadsheets, presentations, internet, email |
| Descriptive writing | Essay, letter, précis |
Note: Tier II General Awareness mixes current affairs with static topics. Reasoning is logical and analytical. Numerical ability stresses timed calculation. The essay can be an idea expansion in English, and the letter can be an application.
