Updates as of September 22, 2026
PGT Biology is post code 828/24 with the Directorate of Education and carries just 13 vacancies, the third smallest subject in the advertisement. The split is extreme: 1 male post, reserved OBC, and 12 female posts made up of 4 unreserved, 6 OBC and 2 SC. There is no ST or EWS post on either sub-list.
OnlineResult (notification mirror)DSSSB's own update for the Biology paper records the second shift on 14 April 2026 under post code 828/24 for the Directorate of Education: 2,729 candidates were allotted and 678 appeared, a turnout of 24.84 per cent. Fewer than 700 candidates therefore competed for the 13 posts on offer.
DSSSB official postMarks for PGT Biology post code 828/24 were released in July 2026, alongside those for PGT Mathematics and an older Political Science code, according to Testbook's result tracker. Several other subjects in the same advertisement had full result notices by then, so Biology candidates should watch for the result notice against the code.
Testbook (as reported)Biology candidates sat the same paper structure as every other subject in the recruitment: one computer-based test of 300 questions for 300 marks in three hours, of which 200 marks came from post-graduate Biology and teaching methodology, with 0.25 deducted for each wrong answer.

| Item | Detail |
|---|---|
| Post code | 828/24, Directorate of Education |
| Vacancies | 13 in total, 1 male (OBC) and 12 female (UR 4, OBC 6, SC 2) |
| Biology and teaching methodology | 200 questions, 200 marks of the 300 |
| General Section I | 100 marks, five parts of 20: Mental Ability, GA, English, Hindi, Numerical |
| Paper and marking | One tier, 3 hours, minus 0.25 per wrong answer |
| Exam sitting | 14 April 2026, second shift, 2 pm to 5 pm |
Two thirds of the Biology candidate's marks come from a single Section II of 200 questions on the post-graduate subject and teaching methodology. The advertisement does not print a topic-wise syllabus for Biology; it defines Section II only as questions pertaining to the post-graduation qualification and the teaching methodology required for the post, which leaves the master's curriculum as the practical scope.

The application window and the April examination block are common to every subject advertised under post codes 824/24 to 834/24; there is one notification and one schedule for the whole PGT recruitment. Only the shift date and the result timeline are specific to Biology, because DSSSB processes each post code separately after the paper.
What this means for your preparation
The mistake specific to PGT Biology is preparing it as a school-level subject. Section II is 200 of the 300 marks and is set against the post-graduate qualification, which means the paper reaches into molecular biology, genetics, cell biology, physiology, systematics and ecology at master's level, not at the depth of a class twelve textbook. The second mistake is misreading the vacancy table: with 13 posts split 1 male and 12 female, a male candidate in Biology is chasing a single OBC-reserved seat.
Thirteen posts, and where each one sits
Biology is one of the thinnest codes in this advertisement. Against Hindi's 91 posts and Economics' 82, post code 828/24 carries 13, of which 12 are on the female sub-list and 1 on the male. The female breakdown is 4 unreserved, 6 OBC and 2 SC; the single male post is OBC. There is no ST or EWS post at all, which means an ST or EWS Biology candidate is competing on the unreserved merit line. Since DSSSB computes merit inside the post code and inside the male or female sub-list, a female OBC Biology candidate is effectively competing for six places and a male unreserved candidate for none. Reading that table before applying is worth more than any number of mock tests, and it is the reason subject choice in DSSSB is a strategic decision and not only an academic one.
What Section II actually covers, and the syllabus gap
DSSSB does not publish a topic list for PGT Biology. The advertisement defines Section II as multiple-choice questions pertaining to the post-graduation qualification and the teaching methodology required for the post, and nothing more granular. The working scope is therefore the master's Biology or Life Sciences curriculum: cell and molecular biology, genetics and genomics, biochemistry and enzymology, plant and animal physiology, developmental biology, microbiology and immunology, systematics and evolution, ecology and environmental biology, and biotechnology. Because the paper is 200 factual single-mark questions rather than a few long answers, breadth beats depth in any one area; a candidate who knows nine areas adequately will outscore one who knows three thoroughly. Teaching methodology questions sit inside the same 200 and cover pedagogy, assessment and classroom practice for senior secondary science.
Where the Biology cut-off historically sits
DSSSB's published cut-offs from the 2022 PGT cycle put Biology at the harder end of the family: 211.53 for unreserved male against 174.66 for SC male and 145.17 for ST male. For comparison, Economics in the same cycle closed at 175.51 for unreserved male. A gap of roughly 36 marks between two subjects in the same recruitment is not a difference in difficulty of the paper, it is a difference in the ratio of strong candidates to posts, and it means a Biology candidate must plan to lose very little in Section I. Treat those figures as historical: they are from a different advertisement with different vacancy counts, and the current 828/24 cut-off will be published with the result notice for the code.
Negative marking and the 200-question grind
With 0.25 deducted per wrong answer across 300 questions, four wrong guesses erase one correct answer. In Biology this matters more than in most subjects because so much of the paper is recall of close alternatives: enzyme names, hormone functions, taxonomic ranks, life-cycle stages, numerical constants. The discipline that pays is separating genuine partial knowledge, where eliminating two options makes a guess clearly positive in expectation, from bare recognition of a term, where it does not. Three hours for 300 questions leaves 36 seconds a question, so a Biology candidate cannot afford to dwell; mark the uncertain items, finish Section II first while attention is fresh, and use the last half hour on Section I where the questions are shorter and the recovery per minute is higher.
Where the 828/24 cycle now stands
The Biology paper was held in the second shift on 14 April 2026, with 678 of 2,729 allotted candidates appearing. Marks for the code were released in July 2026, while several other subjects in the same advertisement had complete result notices by then. Biology candidates should therefore be watching dsssb.delhi.gov.in for the result notice against post code 828/24 and, after it, the call for e-dossier submission, which is the online document verification step DSSSB runs before appointment. Because the post code is small and the shortlist correspondingly short, the interval between result and e-dossier call can be brief; master's degree, B.Ed. and category certificates should be scanned and ready now.
Common questions
What is the post code for DSSSB PGT Biology?
PGT Biology is post code 828/24 under the Directorate of Education in Advertisement 10/2024. Every stage of the process is keyed to that code: the application, the admit card, the shift allotment, the answer key, the result notice, the cut-off and the e-dossier call. When searching for Biology results or cut-offs, search by 828/24 rather than by subject name, and check whether the figure quoted is for the male or the female sub-list, because DSSSB publishes them separately and they differ.
How many vacancies are there for DSSSB PGT Biology?
Thirteen. The male sub-list has a single post, reserved for OBC, and the female sub-list has twelve: four unreserved, six OBC and two SC. No ST or EWS post exists in the Biology code. That makes Biology one of the smallest codes in a 432-post advertisement, well behind Hindi at 91 and Economics at 82. A male candidate outside OBC has no reserved seat in this code at all, which is the single most consequential fact for anyone deciding whether to apply to Biology.
What is the syllabus for DSSSB PGT Biology Section B?
DSSSB does not publish a topic list for it. The advertisement describes Section II only as questions pertaining to the post-graduation qualification and the teaching methodology required for the post, carrying 200 of the 300 marks. In practice that means the master's level Biology or Life Sciences curriculum: cell and molecular biology, genetics, biochemistry, plant and animal physiology, microbiology and immunology, systematics and evolution, ecology, and biotechnology, together with senior secondary science pedagogy and assessment. Anyone quoting a detailed official Biology syllabus is reconstructing it, not citing DSSSB.
What was the DSSSB PGT Biology cut-off?
The cut-off for the current post code 828/24 is published with its result notice and had not appeared at the time of this update, although marks for the code were released in July 2026. From the 2022 PGT cycle, Biology cut-offs reported are 211.53 for unreserved male, 174.66 for SC male and 145.17 for ST male. Those are historical figures from a different advertisement with different vacancy counts and should be used to gauge the level of competition, not as a target for the current cycle.
Is DSSSB PGT Biology harder to clear than other subjects?
The paper is identical in structure for every subject, so difficulty differences come from competition rather than from the question set. On the 2022 figures Biology closed around 36 marks above Economics for the unreserved male category, which reflects a high ratio of strong candidates to a very small number of posts. Against that, actual turnout for the 14 April 2026 Biology sitting was only 24.84 per cent, with 678 of 2,729 allotted candidates appearing, so the field on the day was far smaller than the registration count.
When is the DSSSB PGT Biology result expected?
No date has been announced. DSSSB is releasing this cycle's outcomes post code by post code rather than together: results for History, Physics and Hindi appeared in July 2026, Commerce and Chemistry in August and a Sanskrit code in September, while for Biology marks were released in July 2026. The full result notice for post code 828/24 will be published on dsssb.delhi.gov.in, with individual scorecards through the OARS module on dsssbonline.nic.in, followed by a call for e-dossier submission.
