Alerts and Updates for KVS PGT Biology

Where Biology actually appears in the KVS PGT papers

Every mark of Biology in this recruitment is in Tier-2. The notification states that the expected level of knowledge for PGT posts is post-graduation level, and directs candidates to the detailed subject syllabus on the KVS and NVS websites rather than printing the Biology topic list in the notification itself.

Dates and windows

This schedule is common to every subject in the recruitment: PGT Biology, Physics, Chemistry, English, Hindi and the rest all applied in the same window and sat Tier-1 and Tier-2 on the same days. The only point at which Biology has its own calendar is the phased declaration of Tier-2 results, which has not yet reached the subject. The application window closed in three stages: 4 December 2025 as notified, extended to 11 December 2025 by the CBSE notice of 5 December, and reopened until 15 December 2025 by the CBSE notice of 13 December for candidates whom the KVS/NVS qualification mismatch had blocked, after Corrigendum-2 aligned the two sets of qualifications.

What this means for your preparation

Biology candidates most often misjudge the level of the subject paper. KVS PGTs teach Biology to classes eleven and twelve, so it is natural to prepare from the senior secondary book, but the notification states that the expected level of knowledge for PGT posts is post-graduation. The paper is written for someone who holds a Master's in Biological Science or Life Science, and the school syllabus is the floor rather than the ceiling. The second misjudgement is treating the ten descriptive questions as a bonus round.

Forty marks that cannot be guessed

The Biology Tier-2 paper is 70 questions for 100 marks in two and a half hours: 60 objective questions worth one mark each, with 0.25 deducted for a wrong answer, and 10 descriptive questions worth 40 marks between them. Because Tier-2 supplies 85 per cent of the final merit, the descriptive section alone accounts for roughly 34 per cent of a candidate's selection score, more than double the whole interview. Biology lends itself to descriptive answering better than most subjects: labelled diagrams, pathway sequences, comparative tables and experimental reasoning all score quickly on paper. Candidates who have drilled only multiple-choice questions arrive without any practice at writing a structured 400-word answer under time pressure, and lose marks in the highest-value part of the paper.

The graduation clause decides who can apply

For Biology the notification asks for a Master's in Biological Science or Life Science, or in any specialisation of the concerned subject, but attaches a condition: the candidate must have studied the concerned subject at graduation level. This is the clause that disqualifies people every cycle. A Master's in Microbiology, Biotechnology, Zoology or Botany can satisfy the specialisation limb, but only if Biology or the relevant subject appears in the graduation record. Fifty per cent marks are required in the Master's and separately in the B.Ed., and proficiency to teach in both Hindi and English medium is required. Check the graduation transcript, not just the postgraduate degree, before assuming eligibility.

Biology's competitive position against Physics and Chemistry

Biology has 127 KVS posts against 213 for Physics and 204 for Chemistry, with a further 161 Biology posts on the NVS side under the same notification. Biology also draws from a much larger pool of postgraduates, because Life Science, Zoology, Botany, Microbiology and allied Master's degrees all feed into the one subject, whereas Physics draws mainly from Physics. Fewer posts and a broader eligible pool is the combination that pushes a cut-off up, so Biology candidates should not calibrate expectations against the science subjects with bigger vacancy counts. The 1:10 Tier-1 screen and the 1:3 interview shortlist are applied post-wise, so both ratios bite harder where posts are fewer.

Where the syllabus actually comes from

Notification 01/2025 does not print the Biology topic list. It sets the level as post-graduation and directs candidates to the detailed syllabus published on the KVS and NVS websites. That matters because coaching summaries of the KVS PGT Biology syllabus circulate widely and do not agree with each other, and because the notification's own scheme of examination is the only part of the documentation that is beyond dispute. Work from the official detailed syllabus for topic coverage, and from the scheme of examination for structure. Where the two are silent, the senior secondary Biology curriculum indicates what the job requires, but it does not indicate the depth the paper tests.

What Biology candidates should be doing now

The Biology Tier-2 result has not been declared. CBSE has released Computer Science and Chemistry results on 17 and 21 August 2026 respectively and says the rest are coming in phases, with interview call letters appearing in candidate logins once the schedule is settled with KVS or NVS. There is no public list, so the only reliable check is the candidate login on the application portal. Candidates who sat the Biology paper should keep their login credentials and registration number accessible, keep an eye on the CBSE and KVS notice pages for the next phase press note, and use the interval to prepare for a 15 per cent interview weightage that will be applied to a 1:3 shortlist.

Common questions

How many KVS PGT Biology vacancies are there?

Recruitment Notification 01/2025 advertises 127 PGT Biology posts on the Kendriya Vidyalaya Sangathan side, comprising 53 unreserved, 12 EWS, 34 OBC (non-creamy layer), 19 SC and 9 ST. The same notification carries 161 PGT Biology posts for the Navodaya Vidyalaya Samiti, so the combined Biology total across the two organisations is 288. A revised KVS figure of 146 Biology posts against a revised PGT total of 1,606 has been reported by examination sites but is not in the notification PDF.

What is the KVS PGT Biology exam pattern?

Biology appears only in Tier-2. That paper has 60 objective questions worth 60 marks, with 0.25 marks deducted for a wrong answer, and 10 descriptive questions worth 40 marks, over two hours and thirty minutes, part on OMR and part on paper. Tier-1, sat by every PGT candidate on 10 January 2026, contains no Biology at all: it is 100 questions for 300 marks covering reasoning, numeric ability, computer literacy, general knowledge and two language competency tests, and it only screens candidates at 1:10.

What is the level of the KVS PGT Biology syllabus?

Post-graduation level. Recruitment Notification 01/2025 states that the expected knowledge of candidates for PGT posts is of post-graduation level, and it directs candidates to the detailed subject syllabus published on the KVS and NVS websites rather than printing the Biology topic list itself. This means the senior secondary Biology curriculum, which is what a KVS PGT teaches, is the minimum rather than the target. Coaching summaries of the Biology syllabus vary, so the official detailed syllabus should be the reference point.

Can I apply for KVS PGT Biology with an MSc in Zoology, Botany or Microbiology?

Potentially yes, but with a condition. The notification asks for a Master's degree in Biological Science or Life Science, or in any specialisation of the concerned subject, provided the candidate studied the concerned subject at graduation level. A Master's in Zoology, Botany, Microbiology or a similar specialisation can satisfy the first limb, but the graduation record must carry the concerned subject. Fifty per cent marks are needed in the Master's and separately in the B.Ed., which must be from an NCTE-recognised institution, and age must not exceed 40 years.

When will the KVS PGT Biology Tier-2 result be declared?

No date has been announced. As of 22 September 2026 CBSE had declared Tier-2 results for PGT Computer Science on 17 August 2026 and PGT Chemistry on 21 August 2026, and its press notes state that the results for the remaining posts are being finalised and will be released in phases. Results and shortlisting status appear in the individual candidate login on the application portal rather than as a public list, and interview call letters follow once the schedule is settled with KVS or NVS.

How much does the Biology paper count towards final selection?

A great deal. The merit list is prepared by giving 85 per cent weightage to the Tier-2 score and 15 per cent to the interview, and the Tier-1 mark is not carried forward at all. Since the Tier-2 Biology paper is the only subject assessment in the recruitment, effectively 85 per cent of a candidate's selection score comes from those 70 questions. Within that, the 40 descriptive marks translate to roughly 34 per cent of the final score, which is why written practice matters more than most Biology candidates assume.
