If you are a student of the Bihar Board of Open Schooling and Examination (BBOSE), the BBOSE exam form 2026 is the single most important step between you and your Class 10 or Class 12 open school certificate. Without a successfully submitted examination form, you cannot get an admit card, and without an admit card, you cannot sit for the exam.

For the December 2026 session, the BBOSE examination form was open from 1 October to 20 October 2026 without a late fee, according to the latest reports. That window has just closed, but a late-fee window of Rs 300 is reported to follow in November 2026, so students who missed the first deadline still have a chance. In this guide, you will find the complete application process, eligibility rules, required documents, photo and signature specifications, fee details, common rejection reasons and answers to the questions students ask most.

Important: Dates and fees can change through official notices. Always confirm the final details on the official portal, bboseonline.bihar.gov.in, and the board website, bbose.org, before you pay anything.

What Is the BBOSE Examination Form?

BBOSE runs on a two-step system, and many students confuse the two.

  • Admission or registration form: This is the first step. You enrol with the board, choose your subjects and receive a registration number. For the December 2026 session, admission opened on 23 June 2026, closed without a late fee on 31 August 2026 after an extension, and then ran with a Rs 200 late fee from 1 to 15 September 2026.
  • Examination form: This is the second step. Once you are registered, you must fill a separate form for every session in which you wish to appear. It confirms your subjects for that session and makes you eligible for the admit card.

In short, registration makes you a BBOSE student, while the exam form makes you a candidate for a particular exam. You need both.

For reference, the previous December cycle followed a similar pattern. The Class 12 exam form closed on 10 October 2025 without a late fee, with a Rs 300 late-fee deadline of 17 October 2025. The timetable came out in mid-November, admit cards were released on 26 November, and theory exams ran from 9 to 24 December 2025.

June 2026 session (completed)

The June 2026 session has already been conducted. Practical exams began on 25 July 2026, and theory exams ran from 30 July to 10 August for Class 10 and to 14 August for Class 12. The board later moved two Class 10 papers to 11 and 12 August. Students who appeared in that session and want to improve or clear a failed subject can use the December 2026 form.

Eligibility Criteria for the BBOSE Exam Form 2026

To fill the examination form, you must satisfy the following conditions.

  1. You must already be registered with BBOSE. Only students with a valid registration number can apply for the exam.
  2. Age requirement: For Class 10 you should be over 14 years of age, and for Class 12 you should be at least 15 years of age, supported by age proof.
  3. Previous education: Candidates should have studied under the Bihar Board or another recognised board, and should hold a school leaving certificate or an original transfer certificate.
  4. Gap between Class 10 and Class 12: Reports on the form rules say that applications showing a gap of more than two years between Class 10 and Class 12 can be rejected, so keep your documents consistent.
  5. Failed students: A student who failed the earlier BBOSE Class 10 or Class 12 exam and whose five-year registration period has not expired can apply again after Aadhaar verification.

Documents Required for the BBOSE Exam Form

Keep scanned copies ready before you open the portal. A typical checklist includes:

  • Valid identity proof
  • Aadhaar card (a copy and a working Aadhaar number for verification)
  • Educational certificates and marksheets
  • Original failed marksheet of Class 10 or Class 12 (for students re-appearing)
  • Caste certificate (if applicable)
  • Recent coloured passport-size photograph
  • Scanned signature
  • Registration number and login details received during admission

The board sometimes updates its document list, so read the instruction sheet on the portal before you begin.

BBOSE Exam Form Photo and Signature Size

Uploading files in the wrong size is one of the most common reasons for delays. Follow these specifications.

DocumentMaximum sizePreferred dimensions
Passport-size photographLess than 50 KB200 x 230 pixels
SignatureLess than 50 KB140 x 60 pixels

Photo tips:

  • Use a clear, front-facing photo with a plain background.
  • Do not upload a selfie.
  • Make sure your face is fully visible and the image is not blurred.

Signature tips:

  • Sign with a dark pen on plain white paper.
  • Scan or photograph it in good light and crop closely.
  • Use the same signature you will use on exam day.

How to Fill the BBOSE Exam Form 2026 Online (Step by Step)

  1. Open the official portal

    Visit bboseonline.bihar.gov.in on a laptop or a phone with a stable internet connection. Avoid unofficial lookalike websites.

  2. Log in

    Enter your user ID and password. First-time applicants who have not created an account must register and then log in. If you have forgotten your credentials, use the recovery option on the login page.

  3. Select the examination form link

    Choose the examination form for the December 2026 session and select your class (Secondary or Senior Secondary).

  4. Verify personal details

    Check your name, father’s name, mother’s name, date of birth, category and contact details. Once the form is finally submitted, no changes can be made, so correct everything now.

  5. Confirm educational details and subjects

    Verify your previous qualification and confirm the subjects in which you will appear. Choose carefully, especially if you are re-appearing for failed papers.

  6. Upload photograph and signature

    Upload the images in the required size and format. Preview them to make sure both are clearly visible.

  7. Complete Aadhaar verification

    If you are a repeat candidate, complete the Aadhaar verification step so the system can validate your eligibility.

  8. Pay the examination fee

    Pay online through a debit card, credit card or net banking. If a late fee applies, it is added to the total. Keep the payment receipt.

  9. Final submit and download

    Click Submit. An application ID will be generated. Download the final form and take a printout. Only applications that are finally submitted are considered, so a saved draft is not enough.

BBOSE Exam Fee and Late Fee

The board charges the examination fee per subject, separately for theory and practical papers. Based on the most recent published figures for the previous cycle, the theory fee was Rs 165 per subject and the practical fee was Rs 80 per subject. For the December 2026 session, the portal shows the exact payable amount when you fill the form, so rely on that figure instead of third-party websites.

Type of feeAmount
Theory exam fee (earlier cycle, per subject)Rs 165
Practical exam fee (earlier cycle, per subject)Rs 80
Late fee (December 2026 exam form)Rs 300 (reported)
Late fee (admission, September 2026)Rs 200

Always verify the current fee on the official portal before payment.

Subject Selection Rules for Class 10 and Class 12

Subject choice decides which papers you will write.

  • You need a minimum of five subjects to qualify.
  • At least one and at most two languages from Group A (such as Hindi, English, Urdu, Sanskrit, Bhojpuri, Maithili, Bangla, Arabic and Persian) are compulsory.
  • Three or four subjects come from Group B. For Class 10 this includes Mathematics, Science and Technology, Social Science, Economics, Business Studies, Home Science, Basic Computers and others. For Class 12 it includes Physics, Chemistry, Biology, History, Geography, Mathematics, Economics, Political Science, Accountancy, Psychology, Computer Science, Sociology and more.
  • You can add extra subjects, with a maximum of seven subjects in total.

Reasons Why the BBOSE Exam Form Gets Rejected

A rejected form means lost time and, in some cases, a lost session. Avoid these mistakes:

  1. Unclear or missing photograph or signature. If your face or signature is not visible, the form can be rejected.
  2. Improper documents. Blurred scans, wrong files or documents that do not match your details can cause rejection.
  3. Eligibility gap. A gap of more than two years between Class 10 and Class 12 is flagged in reports on rejections.
  4. Wrong personal details. A mismatch in name, date of birth or parents’ names compared with your certificates creates problems later.
  5. Incomplete submission. Filling the form but not clicking the final submit button, or not paying the fee, means the application is not counted.
  6. False or duplicate information. Providing wrong details can lead to cancellation of candidature.

What to Do If You Missed the Last Date

If you could not fill the form between 1 and 20 October 2026, do not panic.

  • Check for the late-fee window. Reports indicate a Rs 300 late-fee period in November 2026. Watch bbose.org and the portal’s notice board for the exact dates.
  • Keep the extra money ready. The late fee is payable in addition to the normal exam fee.
  • Do not rely on rumours. Dates often shift. Even the admission window for this session was extended, and the portal sometimes lags behind the board’s notice. Trust the board’s own notice first.
  • If no window opens, your next opportunity is the June 2027 session.

What Happens After Submitting the Exam Form?

  1. Verification: The board checks your details, documents and payment.
  2. Admit card: After verification, the admit card is released online, usually in November for the December session. You can download it with your registration number and date of birth. Check the exam centre, shift timing and subjects carefully, and report errors immediately.
  3. Practical and theory exams: Practical exams are normally held first, followed by theory papers in two shifts. Carry your admit card and a valid photo ID on every exam day.
  4. Result: The result for the December session is generally declared a few months later, typically around March.

Smart tips for filling the BBOSE exam form

  • Start early. Portals slow down in the last two days.
  • Prepare resized photo and signature files in advance.
  • Use a personal mobile number and an email you check daily, because the board sends updates there.
  • Keep screenshots of every step, the payment receipt and the final application printout.
  • Never share your password or OTP with anyone who offers to fill the form faster.
  • Check the exam-form notice yourself instead of depending on social media forwards.
