National Board for Academic Standards (NBAS) Revises Class 12 Science Practical Weightage

The National Board for Academic Standards (NBAS) issued a circular on February 9, 2026, revising the weightage for practical components in Class 12 Science board exams to emphasize conceptual understanding. This significant change will impact all students appearing for the Class 12 Science board examinations in the current academic year, aiming to shift focus from rote memorisation to practical application of knowledge.

What's New

According to the circular issued by the National Board for Academic Standards (NBAS) yesterday, a modified weightage distribution has been implemented for practical components in the upcoming Class 12 Science board examinations. This reform, effective for the current exam cycle, aims to place a greater emphasis on conceptual understanding over rote procedures, as stated in the official announcement by the board.

Who It Affects

This revised grading weightage directly affects all students preparing for the Class 12 Science board examinations under the purview of the National Board for Academic Standards (NBAS) during the current academic year. It signals a shift in assessment priorities, encouraging students to focus more on understanding scientific principles and their applications rather than merely memorizing experimental steps for practical exams.

Key Dates / Deadlines

Specific dates for the Class 12 Science board examinations and detailed deadlines related to practical component submissions were not explicitly mentioned in the NBAS circular. However, the revised weightage is effective for the current exam cycle, meaning it applies to the upcoming examinations. Students and educators are advised to refer to subsequent official communications from NBAS for precise timelines and further details.

Official Guidance

The National Board for Academic Standards (NBAS) has advised students and educators to align their preparation and teaching methodologies with the new emphasis on conceptual understanding. The official circular encourages a deeper engagement with scientific principles and their practical applications, moving away from a procedure-centric approach to practical examinations. Students should consult the official NBAS website for the full circular and any supplementary guidelines from the board.

Context / Background

This move by the National Board for Academic Standards (NBAS) aligns with broader national educational reforms, including the National Education Policy (NEP), which advocates for a more holistic and skill-based learning approach. The shift towards conceptual understanding in practical assessments reflects a long-standing recommendation from the Ministry of Education to reduce reliance on rote learning across all levels of schooling in India. This reform aims to equip students with a more robust and applicable scientific foundation for future studies and careers.
