Understanding NIOS Practical Files – Essential Component of Your 2026 Board Examination
Every NIOS Class 12 student enrolled in science subjects like Physics, Chemistry, Biology or practical-oriented subjects like Computer Science, Home Science, Geography, Environmental Science, Mass Communication, Painting, and Data Entry Operations must complete and submit a practical file as a mandatory internal assessment component carrying significant marks in the final grade calculation.
The practical file serves as documented evidence of your laboratory work, experiments performed, observations recorded, and conclusions drawn throughout the academic session. NIOS evaluators assess these files based on specific criteria, including neatness, accuracy, proper formatting, completeness of observations, correctness of calculations, quality of diagrams, and adherence to the prescribed experiment list.
Since 2010, Unnati Education has been helping NIOS students across Delhi, Mumbai, Bangalore, Hyderabad, Chennai, Kolkata, Jaipur, Lucknow, Patna, Chandigarh, and internationally in the UAE, Saudi Arabia, Oman, Qatar, Kuwait, Nepal, and Bhutan prepare perfect practical files that consistently earn full marks in practical examinations.
