NIOS Evaluation System & Certification Criteria 2026 – Complete Guide

The National Institute of Open Schooling (NIOS) is known for its flexible learning and learner-centric approach. Unlike traditional boards (CBSE, ICSE, or State Boards), NIOS has a unique evaluation system and certification criteria that makes it easier for students, working professionals, and differently-abled learners to complete their education.

In this guide, we explain the NIOS evaluation process, pass criteria, weightage system, and certification rules for Class 10 (Secondary) and Class 12 (Senior Secondary) learners in 2026.

1. Components of NIOS Evaluation System

The NIOS evaluation is based on two major components:

1. Theory Examination – Written exams conducted for each subject.

2. Practical Examination – For subjects with lab/practical requirements.

Both components are compulsory (if applicable) and carry separate marks.

2. Weightage of Marks in NIOS

• Theory Paper: 80–90% marks depending on subject.

• Practical Exam: 10–20% marks for science, computer, home science, etc.

• Internal Assessment: NIOS uses Tutor Marked Assignments (TMA) which carry 20% weightage in most subjects.

👉 Example: In Class 12 Physics (100 marks):

• Theory Exam: 70 marks

• Practical Exam: 20 marks

• Assignment (TMA): 10 marks

3. Passing Criteria in NIOS 2025-26

To get a passing certificate, students must meet the following criteria:

• Minimum 33% marks in each subject (separately in theory + practical).

• Aggregate 33% overall across all subjects chosen.

• Must pass in at least 5 subjects (including 1 language) for a valid certificate.

👉 Example: If you have 6 subjects and fail in 1 subject, but pass 5 others, you will still get a certificate.

4. Improvement of Performance

NIOS offers flexibility for improvement:

• Students can re-appear in failed subjects in the next Public Exam or ODES.

• Even if you pass, you may reappear for improvement of marks.

• The best score is retained in your final marksheet.

5. On-Demand Examination & Evaluation

Under the On-Demand Examination System (ODES):

• Results are declared within 45 days of the exam.

• Same evaluation and pass criteria apply.

• Marksheets and certificates are issued just like Public Exams.

6. Grading System in NIOS 2026

NIOS uses a grading system to represent marks:

• A – Excellent (80% & above)

• B – Very Good (60–79%)

• C – Good (45–59%)

• D – Average (33–44%)

• E – Unsuccessful (Below 33%)

👉 Example: If you score 72% in English, your grade will be B (Very Good).

7. Certification Rules in NIOS

For Secondary (Class 10):

• Must pass at least 5 subjects (1 language + 4 others).

• Additional subjects are optional.

For Senior Secondary (Class 12):

• Must pass at least 5 subjects (including 1 or 2 languages).

• Additional subjects can also be chosen.

Once students pass, NIOS issues the following:

1. Marksheet (with subject-wise scores)

2. Provisional Certificate (temporary proof until original arrives)

3. Migration-Cum-Transfer Certificate (for admission to higher studies)

4. Pass Certificate (final document)

8. Evaluation for Differently-Abled Learners

NIOS provides special provisions such as:

• Extra time in exams.

• Amanuensis (scribe) facility.

• Alternative subjects (like Home Science instead of Maths).

• Relaxation in practical exams if required.

9. Re-checking & Re-evaluation

• Students can apply for re-checking of answer sheets (₹300 per subject).

• Re-evaluation facility is available at Class 12 level (₹800 per subject).
