HBBVS Eligibility Criteria 2026-27: Class 9, Medium and Fees

The Dr. Homi Bhabha Balvaidnyanik Competition (HBBVS, also called DHBBVC) is a four-stage science competition conducted by the Greater Bombay Science Teachers' Association (GBSTA), also known as the Mumbai Science Teachers' Association, since 1981. The HBBVS eligibility criteria are short, but a few details, such as medium, region and registration route, decide how and where your child competes.

This guide follows the official DHBBVC 2026-27 information circular and schedule published on msta.in. It focuses on Class 9 (Std IX) students and notes where the rules for Class 6 differ. You will find who can participate, medium and board rules, regions and centres outside Maharashtra, fees, dates, stage-wise selection rules and real-life scenarios to check where your child stands.

Who Can Participate in HBBVS

The core rule is simple: only students studying in Std 6 or Std 9 in the current academic year can take part. For the 2026-27 cycle, that means students enrolled in Std 6 or Std 9 during the 2026-27 school year. Students of Std 7, 8 or 10 cannot register, even if they are strong in science.

Std 6 and Std 9 are separate competitions with their own papers, practicals and merit lists. The table below shows how the Class 9 track differs from Class 6.

Point

Class 9 (Std IX)

Class 6 (Std VI)

Syllabus base

Science textbooks of Std 7, 8 and 9

Science textbooks of Std 4, 5 and 6

Practical round

3 experiments: one each in Physics, Chemistry and Biology, 10 marks each

5 experiments of 6 marks each

Practical date (2026-27)

24 January 2027

10 January 2027

Written test, interviews and medals

Same structure and rules for both standards

Because only two standards are eligible, a student gets one chance in Std 6 and one in Std 9. If your child is in Std 9 this year, this is the final opportunity to compete for the Balvaidnyanik title.

HBBVS Age Limit

The official circular does not prescribe a minimum or maximum age. Eligibility depends only on the standard the student is studying in. The registration form asks for the date of birth, but it is used for records, not as an age cut-off. A Std 9 student who is slightly older or younger than classmates can participate without any issue.

Medium of the Competition

The competition is held in English and Marathi. The 2026-27 circular lists Marathi, English and Semi-English as accepted mediums of study. Students from Semi-English sections must choose either English or Marathi as their medium of answering at the time of registration.

  • The medium is locked: Once selected, the medium cannot be changed for any later stage, including the practical and interview rounds.

  • The handbook follows the medium: The official handbook included in the fee is not exchanged if you later want a different medium.

  • The fee depends on the medium: Through school, English medium costs Rs. 520 and Marathi medium Rs. 420 for 2026-27.

For Semi-English students, pick the language in which your child reads and understands science terms most comfortably, since the practical and interview rounds will also follow that medium. Students from other mediums, such as Hindi, need to answer in English or Marathi, since the paper is not offered in other languages.

Boards and Merit Categories

Students from all boards can participate: Maharashtra State Board (SSC), CBSE, ICSE, IB and other state boards. The written test draws mainly on Maharashtra State Board science textbooks, along with related content from CBSE, ICSE and IB books. For Class 9, the official weightage is about 10 percent from Std 7, 20 percent from Std 8, 60 percent from Std 9 and 10 percent from general knowledge in science.

The board matters for one more reason. Selection at every stage happens separately for each region, each standard and each medium, with State Board and other boards treated as separate categories. A CBSE English-medium student in Pune, for example, is ranked against other-board English-medium students in the Pune region, not against all students in Maharashtra.

For students outside the State Board, this means reading the relevant Maharashtra State Board science chapters is worthwhile, even though they compete only with students from other boards.

Regions and Students Outside Maharashtra

GBSTA organises the competition region-wise. Your region is decided by where your school is located, and merit lists are prepared region by region.

Other than Maharashtra

Other states in India and students abroad

Students from other states and abroad

Students outside Maharashtra are eligible and fall under the "Other than Maharashtra" region. According to the 2026-27 circular, if more than 100 students are registered, a centre is provided in the home state. Otherwise, candidates select a city in Maharashtra as their centre and can give three choices.

Older pages still mention a minimum of 50 students for a centre outside Maharashtra. That figure comes from earlier cycles, so follow the latest circular. Since all four stages are offline, a student outside Maharashtra should plan for travel if selected for the later rounds. In 2025-26, the interview round was held in Mumbai.

Eligibility for Each Stage

Registering makes a student eligible for Stage 1 only. Each later stage has its own selection rule, applied separately within each region, standard, medium and board category.

Stage

Format and marks

Who moves ahead

Stage 1: Written test

100 MCQs, 100 marks, 90 minutes

Top 7.5 percent qualify for Stage 2 and get a merit certificate; others scoring above 35 marks get a passing certificate

Stage 2: Practical test

30 marks in 30 minutes; Class 9 does one experiment each in Physics, Chemistry and Biology

30 percent of Stage 1 marks plus Stage 2 marks are combined; top 10 percent qualify for Stages 3 and 4

Stage 3: General interview

30 marks, 5 to 7 minutes

How medals are decided

The final score is out of 120: Stage 1 marks converted to 30, plus up to 30 each from Stages 2, 3 and 4. A student selected for Stages 3 and 4 who completes both is assured of a medal.

Medal

Who gets it

Award (2026-27)

Since only the top 7.5 percent clear Stage 1, the written test is the real filter. For details on marks and timing.
