To enhance academic relevance and ensure students are better aligned with evolving educational standards, the Council for the Indian School Certificate Examinations (CISCE) has officially rolled out a revised syllabus for several key subjects for ISC Classes 11 and 12. This announcement will impact students beginning the academic year 2024-25 and those appearing for the ISC 2025 board examinations.
Revised Curriculum to Take Effect from 2024-25
The updated syllabus will be implemented for Class 11 students in the academic session 2024-25, while Class 12 students appearing for the ISC 2025 board exams will also study under the new structure. The changes are part of CISCE’s ongoing efforts to modernize the curriculum and better equip students with knowledge and skills that meet current academic and industry standards.

The syllabus changes span across a wide array of disciplines. For Class 11, the revised curriculum will apply to:

Schools Urged to Disseminate Information
In a formal circular, the CISCE instructed the heads of all ISC-affiliated schools to share this crucial information with students, teachers, parents, and guardians as soon as possible. The council emphasized that early awareness and preparation will be essential in helping students transition smoothly to the new syllabus structure and perform confidently in their examinations.
Why This Matters
This curriculum revision follows the successful completion of the 2025 board examinations — with ICSE (Class 10) exams held from February 18 to March 27 and ISC (Class 12) exams from February 13 to April 5. By realigning syllabi, CISCE aims to ensure that its educational offerings remain dynamic, comprehensive, and in tune with the latest developments in various academic fields.
